ABSTRACT

Background: Due to Covid-19, the lockdown was imposed throughout the nation on 24 march 2020 and Covid-19 is not over yet, cases are still coming. Food insecurity was already a problem but it became even more challenging during the pandemic. Especially rural older adult people have had to deal with the problem of food and health-related issues due to the pandemic. Objective: This study aimed to assess food consumption behavior and lifestyle changes among rural older adults before and during the Covid-19 pandemic. Material and Methods: A retrospective cross-sectional study has been done; a multistage random sampling technique was used to select the participants. 450 participants were taken aged 60 and above for final analysis. The survey was conducted in the rural areas of the Varanasi District, Uttar Pradesh through personal interviews. The McNemar and Wilcoxon sign rank tests were used to examine differences before and during the Covid-19 pandemic, adopting the statistical significance of p< 0·05. Results: Mean age of participants were found 66.72 years. 66.0% of people faced a shortage of food. 40.9% of people reported that they had reduced their food intake and 39.6% reported that the reduction in food intake was due to the rise in the price of edible items. 27.6% of participants reported a reduction in body weight. There was a significant percentage decrease in consumption of milk products, pulse, and green vegetables(p<0.001), a percentage decrease in initiating and maintaining sleep (p<0.001), and worse health conditions (p<0.001). Conclusions: Food consumption behavior and lifestyles have changed significantly during the Covid-19 pandemic among rural older adults. Although some lifestyles haven’t changed significantly, the quantity of food and health conditions were compromised.

ABSTRACT

PurposeAmid the COVID-19 contamination, people are bound to use contactless FinTech payment services. Because of restrictions on physical movement and avoidance of touching physical money, people willingly choose mobile payment, resulting in enormous growth in FinTech payment service industries. Because of this, this study aims to examine the effect of factors affecting Gen X and Millennials users to use FinTech payment services.Design/methodology/approachThe authors used 328 responses collected through convenience sampling of Indian users aged between 26 and 57 years in the Delhi-NCR region who are users of FinTech payment services.FindingsThe authors' findings verified that in India, perceived COVID-19 risk, perceived severity for COVID, individual mobility, subjective norms, perceived ease of use and perceived usefulness have statistically significant impacts on FinTech payment services during the COVID-19 pandemic. Structural equation modelling was used to study the proposed research model. Overall, the model predicted 76.9 % of the variation in intention to use FinTech payment services by the abovesaid variables by Indian users during a pandemic.Practical implicationsThis study will provide valuable insight to all FinTech service providers and stakeholders in planning and designing the concerned policy. It will be able to draw the attention of users more.Originality/valueThis research added a valuable theory to the existing technology adoption model (TAM) theory. It demonstrated the utility of the above variables in adopting and using FinTech payment services, which will help service providers to develop future strategies because of the COVID-19 pandemic.

ABSTRACT

INTRODUCTION: Various vaccines for protection against COVID-19 were provided emergency approval in late 2020 to early 2021. There is a scarcity of long-term safety data for many of these. OBJECTIVE: The main aim of this study is to provide the one-year safety results of the ChAdOx1-nCoV-19/AZD1222 vaccine and determine the risk factors of adverse events of special interest (AESIs) and persistent AESIs. METHODS: This was a prospective observational study conducted from February 2021 to April 2022 in a tertiary hospital in North India and its two associated centers. Health care workers, other frontline workers, and the elderly vaccinated with the ChAdOx1-nCoV-19 vaccine constituted the study population. Individuals were contacted telephonically at pre-decided intervals for one year and health issues of significant concern were recorded. Atypical adverse events developing after a booster dose of the COVID-19 vaccine were assessed. Regression analysis was conducted to determine risk factors of AESI occurrence and determinants of AESIs persisting for at least one month at the time of final telephonic contact. RESULTS: Of 1650 individuals enrolled, 1520 could be assessed at one-year post-vaccination. COVID-19 occurred in 44.1% of participants. Dengue occurred in 8% of participants. The majority of the AESIs belonged to the MedDRA® SOC of musculoskeletal disorders (3.7% of 1520). Arthropathy (knee joint involvement) was the most common individual AESI (1.7%). Endocrinal disorders such as thyroid abnormalities and metabolic disorders such as newly diagnosed diabetes developed in 0.4% and 0.3% of individuals, respectively. Regression analysis showed females, individuals with a pre-vaccination history of COVID-19, diabetes, hypothyroidism, and arthropathy had 1.78-, 1.55-, 1.82-, 2.47- and 3.9-times higher odds of AESI development. Females and individuals with hypothyroidism were at 1.66- and 2.23-times higher risk of persistent AESIs. Individuals receiving the vaccine after COVID-19 were at 2.85- and 1.94 times higher risk of persistent AESIs compared, respectively, to individuals with no history of COVID-19 and individuals developing COVID-19 after the vaccine. Among participants receiving a booster dose of the COVID-19 vaccine (n = 185), 9.7% developed atypical adverse events of which urticaria and new-onset arthropathy were common. CONCLUSION: Nearly half of the ChAdOx1-nCoV-19 vaccine recipients developed COVID-19 over one year. Vigilance is warranted for AESIs such as musculoskeletal disorders. Females, individuals with hypothyroidism, diabetes, and pre-vaccination history of COVID-19 are at higher risk of adverse events. Vaccines received after natural SARS-CoV-2 infection may increase the risk of persistence of adverse events. Sex and endocrinal differences and timing of the COVID-19 vaccine with respect to natural infection should be explored as determinants of AESIs in the future. Pathogenetic mechanisms of vaccine-related adverse events should be investigated along with comparisons with an unvaccinated arm to delineate the overall safety profile of COVID-19 vaccines.

ABSTRACT

There have been reports of neurodegenerative diseases including Parkinsonism, Alzheimer's disease and Creutzfeldt Jakob disease following COVID-19. The exact pathogenesis of these has not been elucidated yet though authors have proposed the possibility of the hyper-inflammatory state of COVID-19 acting as a trigger through cytokine-induced inflammatory response of brain microglia and astrocytes, as well as damage resulting from the central nervous system hypoxia of severe COVID-19, or even the direct pathogenetic actions of SARS-CoV-2 on the brain. There have also been reports of worsening of Parkinsonian symptoms, new onset movement disorders and even rapidly progressive dementia following COVID-19 vaccination using different vaccine types. The occurrence of protein-aggregation mediated neurodegenerative syndromes following both COVID-19 and vaccination led us to explore the common thread of the Spike (S) protein as a potential mediator. In the current study, we investigated the interactions of S protein of SARS-CoV-2 with α-synuclein.

ABSTRACT

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) caused global pandemic and drastically affected the humankind. Mitochondrial mutations have been found to be associated with several respiratory diseases. Missense mutation and pathogenic mitochondrial variants might unveil the potential involvement of the mitochondrial genome in coronavirus disease 2019 (COVID-19) pathogenesis. The present study aims to elucidate the role of mitochondrial DNA (mtDNA) mutations, mitochondrial haplogroup, and energy metabolism in disease severity. The study was performed on 58 subjects comprising COVID-19-positive (n = 42) and negative (n = 16) individuals. COVID-19-positive subjects were further categorized into severe deceased (SD), severe recovered (SR), moderate (Mo), and mild (Mi) patients, while COVID-19-negative subjects were healthy control (HC) for the study. High throughput next-generation sequencing was done to investigate mtDNA mutations and haplogroups. The computational approach was applied to study the effect of mtDNA mutations on protein secondary structure. Real time polymerase chain reaction was used for mtDNA copy number determination and mitochondrial function parameters were also analyzed. We found 15 mtDNA mutations in MT-ND5, MT-ND4, MT-ND2, and MT-COI genes uniquely associated with COVID-19 severity affecting the secondary structure of proteins in COVID-19-positive subjects. Haplogroup analysis suggests that mtDNA haplogroups M3d1a and W3a1b might be potentially associated with COVID-19 pathophysiology. The mitochondrial function parameters were significantly altered in severe patients (SD and SR; p < 0.05). No significant relationship was found between mtDNA mutations and oxidative stress markers (p > 0.05). The study highlights the importance of mitochondrial reprogramming in COVID-19 patients and may provide a feasible approach toward finding a path for therapeutic interventions to COVID-19 disease.

ABSTRACT

Covid 19 pandemic has severe implications on health and life of people. Asia being the most populous region has higher fatalities burden. Health infrastructure, stringent preventive measures by the government and public participation through adhering to social distancing have influence to check on fatalities' burden. The level of Social capital as well as voters' participation in a particular country can have influence on containment of COVID cases and fatalities. In this context, the main objectives of this study are to analyse pattern and trend of death burden for 45 Asian countries and impact of stringency measures by government, and voters' turnout ratio on death burden. However, for regression analysis only 32 countries are taken into account considering the availability of data for all variables. Multiple linear regression analysis is employed in a cross-sectional framework and Ordinary least square estimation technique with heteroscedastic adjusted standard errors have been used for estimation of coefficients. The results show that southern Asia contributes the highest share of fatality cases in total fatality cases of Asia with 71.43% share. It also has the highest share of confirmed cases in total confirmed cases of Asia with 71.72%. However, when we take the population into account, Western Asia leads in the share of confirmed COVID-19 cases and its associated fatality cases per million populations in Asia as compared to other Asian regions. The factors like health infrastructure and voters' turnover ratio are found to be significant and potential in reducing the new deaths per million populations. Though the coefficient of Stringency index has been negative and it did not emerge to be significant in Asian countries. The COVID related fatalities in Asian region are urban centric and urbanization proxy is found to be positive and significant. Diabetes prevalence rate has some heterogeneous result and in the present study its coefficient is not in the hypothesized direction. . The Countries should ramp up health infrastructure and necessary preparedness to deal with the subsequent waves and COVID related fatalities. Importance need to be given people's participation and their shared responsibilities in dealing with COVID cases and checking on fatalities. The realisation of social responsibility among the masses can lead to community participation and adhering to the protocols imposed by the government and helps in checking on spread of virus and associated death.

ABSTRACT

Interface mimicry, achieved by recognition of host-pathogen interactions, is the basis by which pathogen proteins can hijack the host machinery. The envelope (E) protein of SARS-CoV-2 is reported to mimic the histones at the BRD4 surface via establishing the structural mimicry; however, the underlying mechanism of E protein mimicking the histones is still elusive. To explore the mimics at dynamic and structural residual network level an extensive docking, and MD simulations were carried out in a comparative manner between complexes of H3-, H4-, E-, and apo-BRD4. We identified that E peptide is able to attain an 'interaction network mimicry', as its acetylated lysine (Kac) achieves orientation and residual fingerprint similar to histones, including water-mediated interactions for both the Kac positions. We identified Y59 of E, playing an anchor role to escort lysine positioning inside the binding site. Furthermore, the binding site analysis confirms that E peptide needs a higher volume, similar to the H4-BRD4 where both the lysine's (Kac5 and Kac8) can accommodate nicely, however, the position of Kac8 is mimicked by two additional water molecules other than four water-mediated bridging's, strengthening the possibility that E peptide could hijack host BRD4 surface. These molecular insights seem pivotal for mechanistic understanding and BRD4-specific therapeutic intervention. KEY POINTSMolecular mimicry is reported in hijacking and then outcompeting the host counterparts so that pathogens can rewire their cellular function by overcoming the host defense mechanism.The molecular recognition process is the basis of molecular mimicry. The E peptide of SARS-CoV-2 is reported to mimic host histone at the BRD4 surface by utilizing its C-terminally placed acetylated lysine (Kac63) to mimic the N-terminally placed acetylated lysine Kac5GGKac8 histone (H4) by interaction network mimicry identified through microsecond molecular dynamics (MD) simulations and post-processing extensive analysis.There are two steps to mimic: firstly, tyrosine residues help E to anchor at the BRD4 surface to position Kac and increase the volume of the pocket. Secondary, after positioning of Kac, a common durable interaction network N140:Kac5; Kac5:W1; W1:Y97; W1:W2; W2:W3; W3:W4; W4:P82 is established between Kac5, with key residues P82, Y97, N140, and four water molecules through water mediate bridge. Furthermore, the second acetylated lysine Kac8 position and its interaction as polar contact with Kac5 were also mimicked by E peptide through interaction network P82:W5; W5:Kac63; W5:W6; W6:Kac63.The binding event at BRD4/BD1 seems an induced-fit mechanism as a bigger binding site volume was identified at H4-BRD4 on which E peptide attains its better stability than H3-BRD4.We identified the tyrosine residue Y59 of E that acts like an anchor on the BRD4 surface to position Kac inside the pocket and attain the interaction network by using aromatic residues of the BRD4 surface.Communicated by Ramaswamy H.

ABSTRACT

Guillain-Barré Syndrome (GBS), an autoimmune neurological disease of peripheral nerves, has been causally associated with COVID-19 vaccination in adults. However, no such report has been published so far in children. We describe a 13-year-old female child who presented to the emergency department with complaints of bilateral upper limb, lower limb and truncal weakness over 3 days following first dose of recombinant protein subunit COVID-19 vaccine (Corbevax). Clinical examination and nerve conduction studies showed pure motor axonal polyneuropathy with absent compound muscle action potential (CMAP) in all sampled nerves of upper and lower limbs which was consistent with the diagnosis of GBS after ruling out possible alternative aetiologies. A temporal association between first dose of protein subunit COVID-19 vaccine administered a day prior and symptom onset was noted. The causality assessment using the World Health Organization (WHO) tool for adverse event following immunization (AEFI) assessment indicated vaccine product-related reaction categorized as A1. The patient's clinical condition improved after seven sessions of plasmapheresis. The purpose of this report is to create awareness among health care professionals about COVID-19 vaccine-induced GBS in children as early diagnosis and management can be critical in avoiding complications and improving patient outcomes.

ABSTRACT

Background Dengue which is endemic in India and has been occurring for decades apparently witnessed a rise in disease burden in 2021 in specific regions of the nation. We aim to explore less studied risk factors of Dengue occurrence and severity in the post-COVID-19 and post-COVID-19 vaccination era. Methods This was an exploratory analysis involving participants from two prior observational studies conducted during the period of Feb 2021-April 2022 in a tertiary hospital in North India. Healthcare workers constituted the majority of study participants. Individuals were stratified into five groups based on COVID-19 infection and timing of vaccination: CovidNoVaccine (CNV), VaccineNoCOVID (VNC), CovidAfterVaccine (CAV), VaccineAfterCOVID (VAC) and NoVaccineNoCovid (NVNC) groups. The occurrence of lab-confirmed Dengue and severe forms of Dengue were the main outcomes of interest. We tried to predict determinants of Dengue occurrence and severity with a particular focus on COVID-19 history and vaccination status. Results A total of 1520 vaccinated individuals and 181 unvaccinated individuals were included. Of these 1701 participants, symptomatic Dengue occurred in 133 (7.8%) and was of 'severe' category in 42 (31.6%). Individuals with a history of COVID-19 in 2020 had 2 times higher odds of developing symptomatic Dengue. The VAC group had 3.6, 2- and 1.9 times higher odds of developing Dengue than the NVNC, VNC, and CAV groups. The severity of dengue was not affected by COVID-19 or COVID-19 vaccination. Conclusions COVID-19 may enhance the risk of developing symptomatic dengue. Future research dealing with long COVID should explore the propensity of COVID-19 victims towards symptomatic forms of other viral illnesses. Individuals receiving the COVID-19 vaccine after recovering from COVID-19 particularly seem to be at greater risk of symptomatic dengue and need long-term watchfulness. Possible mechanisms, such as antibody-mediated enhancement or T-cell dysfunction, should be investigated in COVID-19-recovered and vaccinated individuals. Further large-scale, multicentric, robust studies with a better enrolment of unvaccinated people will help understand the interplay of factors involved in COVID-19 and Dengue.

ABSTRACT

Aim: This study investigated the knowledge and attitudes towards COVID-19 in Bangladeshi adults by online and phone survey methods during the early stage of its spread. Methods: Data were collected through phone calls (April 14-23, 2020) and online survey (April 18-19, 2020) in Bangladesh. The questionnaire had 20 knowledge questions with each correct response getting one point and incorrect/don’t know response getting no point (maximum total knowledge score 20). Participants scoring >17 were categorized as having good knowledge. Results: The percentages of good knowledge holders were 57.6%, 75.1%, and 95.8% in the phone, online non-medical, and online medical participants, respectively. Most of the phone and online participants had good knowledge of the preventive practices of COVID-19. However, among the non-medical participants (both phone and online), the correct response rates were lower than 80% for the knowledge questions asking about the facts that - some patients may have no symptoms, diarrhea is a symptom of this disease and that it cannot be prevented by any currently available medication. Male gender, higher education, living in town/urban areas, good financial condition, and use of internet were positively associated with higher knowledge score among the non-medical participants. However, higher knowledge score was associated with having less confidence in the final control of COVID-19. Conclusion: Our study identified some COVID-19 information that were less known among the participants and the potential factors that were associated with having good versus poor knowledge. Besides, this study sheds light on the attitude of Bangladeshi adults towards COVID-19.

ABSTRACT

Vaccination for coronavirus disease 2019 (COVID-19) is a critical strategy in controlling the current pandemic of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). After widespread COVID-19 vaccine imple-mentation, isolated case reports about myocarditis as a potential adverse reaction started coming. As of November 12, 2021, Centers for Disease Control and Prevention (CDC) has reported 1793 cases of myocarditis or pericarditis among young people with age 12-29 years, most cases have been reported in the male adolescent age group after the second dose of mRNA COVID-19 vaccines. It is very important to monitor the safety standards and adverse reactions of vaccines to effectively implement the vaccination policies. The CDC and the United States Food and Drug Administration actively monitor vaccine-associated adverse reactions a well-known platform such as Vaccine Adverse Event Reporting System. CDC continues to recommend COVID-19 vaccines and booster doses for eligible individuals (age limit according to the type of vaccine) after careful consideration from risk-benefit assessment and favorable outcomes from vaccination. Mechanisms behind COVID-19 vaccine-induced myocarditis are not clear yet but several possibilities such as molecular mimicry between the spike protein of SARS-CoV-2 and self-antigens, immune response to mRNA, and activation of host immunological system, trigger of the pre-existing dysregulated immunological system have been documented in the literature. Overall, data suggests a good prognosis, especially in young patients. In this review article, we cover currently available data on COVID-19 vaccine-related myocarditis incidence, concerns, possible mechanisms of myocarditis, current treatment, and outcome trends, risk vs benefit assessment of COVID-19 vaccination in this current pandemic.

ABSTRACT

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has adversely affected humankind and caused millions of deaths globally since January 2020. Robust and quick serological tests such as antibody detection assays for SARS-CoV-2 provide relevant information and aid in the process of vaccine development and diagnostics, as well as in sero-epidemiological monitoring of antibody response to the virus. The receptor-binding domain (RBD) of spike and nucleocapsid protein are specific targets for detecting SARS-CoV-2 antibodies. Here, we present the development of a stable spike (S) and nucleocapsid (N) protein-based ELISA antibody detection test "CoroSuchak," with 99% sensitivity, 98% specificity, cost-effective, and detection in a minimum time for serodiagnosis and mass screening of the population for antibodies against SARS-CoV-2. Blood samples were analyzed from 374 SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) positive, 772 negative and asymptomatic, and 874 random groups of subjects. We found that the antibody titer was significantly higher (p < 0.0001) in infected and vaccinated group compared to the only vaccinated and only infected group. Using enzyme-linked immunosorbent assay (ELISA), we detected SARS-CoV-2 immunoglobulin G (IgG) antibodies in 118/123 (96%) infected individuals, 570/653 (87%) non-infected but vaccinated individuals, 231/237 (97%) individuals who were both infected and vaccinated, and 499/874 (57%) from randomly selected individuals from the first and second waves of the pandemic. Similarly in the third wave, 14/14 (100%) infected and 16/20 (80%) RT-PCR-negative but symptomatic subjects were detected. Thus, the highly sensitive and specific in-house developed ELISA antibody detection kit "CoroSuchak" is extremely useful to determine the seroprevalence of SARS-CoV-2 antibodies in the coronavirus-exposed population. KEY POINTS: •Indigenous kit using a combination of spike and nucleocapsid proteins and peptide sequences. •High sensitivity and specificity to detect variants. •Highly sensitive for mass screening.

ABSTRACT

The current analysis is a part of an ongoing observational study that began in February 2021 in the Sir Sunder Lal Hospital (Varanasi, Uttar Pradesh) in northern India and is expected to continue until June 2022. This analysis aimed to delineate the clinical presentation and risk factors of occurrence and severity of COVID-19 in vaccinated individuals. The study enrolled health-care workers and the elderly receiving the COVID-19 vaccine at one of three centers linked to the study hospital. The participants received the ChAdOx1 nCoV-19 (Oxford-AstraZeneca) vaccine based on the chimpanzee adenovirus platform (manufactured in India by the Serum Institute of India). The adenovirus codes for the spike (S) protein of SARS-CoV-2. Participants were contacted by phone at pre-decided intervals and questioned about the occurrence of COVID-19, clinical presentation, severity, and persistence of symptoms. A logistic regression analysis was performed to predict the risk factors of occurrence and severity of COVID-19. Of the 1,500 participants included in the analysis, 418 developed COVID-19 (27.9%). Fever was the most common symptom (72%), followed by cough (34%) and rhinitis (26%). Cardiovascular involvement was seen in more than 2% of individuals, and 11% had post-COVID-19 complaints. Regression analysis showed 1.6 times greater odds of contracting the disease in females and in those younger than 40 years, 1.4 times greater odds in individuals who were overweight, and 2.9 times greater odds in those receiving only one dose, compared with respective comparators. Individuals receiving two doses at a gap of ≤ 30 days had 6.7 times greater odds of infection than those receiving at a > 60-day interval. There was no association between COVID-19 occurrence in the vaccinees and pre-vaccination history of SARS-CoV-2 infection. Males were at a 3.6 times greater risk, and persons with preexisting lung disease-mainly asthma-had a 5.9 times greater risk of experiencing moderate to severe COVID-19 than comparators. While an extended interval between the two vaccine doses seems to be a better strategy, gender differences and an association of asthma phenotypes with COVID-19 need to be explored.

ABSTRACT

The purpose of the study was to have a better clarification of the popular themes studied by Indian researchers during the period 2000 to 2021. The paper helped in identifying the trends and development in research area in context to Indian Hospitality and tourism sector. The study selected a total of 1821 research papers of Indian origin from the scopus database during a span of 22 years (2000-2021). The selected publications were analyzed using different bibliometric methods of analysis using biblioshiny and VOS viewer within the scope of several parameters. The complete time period was divided into three distinct timeframes to study the research trends during the period. The maximum number of articles published in recent years, i.e. 2020, while minimum article publications in 2001. 1241 citations received in 2019 while only 110 citations received in 2005. 'Worldwide Hospitality and Tourism Themes' and 'International Journal of Contemporary Hospitality Management' were found to be the most productive journals. While ‘Singh S.’ is the most productive authors with a maximum number of articles, while 'Jauhari V' has the most number of citations for his work. Sustainability and conservation are the themes of common interest irrespective of timeframe, while the role of social media, covid 19 are recent trending topics for researchers. The study does contain certain limitations despite contributing significantly to the Hospitality and tourism literature in Indian context. The present study did not included publications other than articles like conferences proceedings, book chapters and dissertations etc. Selection of tools used and the keywords chosen for the study also limit the outcome. The findings of the analysis is helpful in better understanding the direction of research themes in the hotel and tourism industries. Evaluation of prominent authors and their work again helps on focusing the trending themes in the sector among researchers. Furthermore it helps future researchers in identifying key issues in the field of hospitality and tourism. The sample for this study, to the best of the authors' knowledge, was the most comprehensive collection of articles published in India's hospitality and tourism industries. This study adds substantially to the existing literature by highlighting current research orientations and trends in hospitality and tourism.

ABSTRACT

Background There is paucity of real-world data on COVID-19 vaccine effectiveness from cohort designs. Variable vaccine performance has been observed in test-negative case-control designs. There is also scarce real-world data of health issues in individuals receiving vaccines after prior COVID-19, and of adverse events of significant concern (AESCs) in the vaccinated. Methods: A cohort study was conducted from July 2021 to December 2021 in a tertiary hospital of North India. The primary outcome was vaccine effectiveness against COVID-19 during the second wave in India. Secondary outcomes were AESCs, and persistent health issues in those receiving COVID-19 vaccines. Regression analyses were performed to determine risk factors of COVID-19 outcomes and persistent health issues. Results: Of the 2760 health care workers included, 2544 had received COVID-19 vaccines, with COVISHIELD (rChAdOx1-nCoV-19 vaccine) received by 2476 (97.3%) and COVAXIN (inactivated SARS-CoV-2 vaccine) by 64 (2.5%). A total of 2691 HCWs were included in the vaccine effectiveness analysis, and 973 COVID-19 events were reported during the period of analysis. Maximum effectiveness of two doses of vaccine in preventing COVID-19 occurrence was 17% across three different strategies of analysis adopted for robustness of data. One-dose recipients were at 1.27-times increased risk of COVID-19. Prior SARS-CoV-2 infection was a strong independent protective factor against COVID-19 (aOR 0.66). Full vaccination reduced moderate-severe COVID-19 by 57%. Those with lung disease were at 2.54-times increased risk of moderate-severe COVID-19, independent of vaccination status. AESCs were observed in 33/2544 (1.3%) vaccinees, including one case each of myocarditis and severe hypersensitivity. Individuals with hypothyroidism were at 5-times higher risk and those receiving a vaccine after recovery from COVID-19 were at 3-times higher risk of persistent health issues. Conclusions: COVID-19 vaccination reduced COVID-19 severity but offered marginal protection against occurrence. The possible relationship of asthma and hypothyroidism with COVID-19 outcomes necessitates focused research. With independent protection of SARS-CoV-2 infection, and high-risk of persistent health issues in individuals receiving vaccine after recovery from SARS-CoV-2 infection, the recommendation of vaccinating those with prior SARS-CoV-2 infection needs reconsideration.
