BACKGROUND: The Oxford-AstraZeneca vaccine (Covishield) was the first to be introduced in Bangladesh to fight the ongoing global COVID-19 pandemic. As this vaccine had shown some side-effects in its clinical trial, we aimed to conduct a study assessing short-term adverse events following immunization (AEFIs) in Bangladesh. METHOD: A cross-sectional study was conducted on social and electronic media platforms by delivering an online questionnaire among people who had taken at least one dose of the COVID-19 vaccine. The collected data were then analysed to evaluate various parameters related to the AEFIs of the respondents. RESULTS: A total of 626 responses were collected. Of these, 623 were selected based on complete answers and used for the analysis. Most of the respondents were between 30-60 years of age, and 40.4% were female. We found that a total of 8.5% of the total respondents had been infected with the SARS-CoV-2 virus. Our survey revealed that out of 623 volunteers, 317 reported various side-effects after taking the vaccine, which is about 50.88% of the total participants. The majority of participants (37.07%, 231/623) reported swelling and pain at the injection site and fever (25.84%, 162/623); these were some of the common localized and generalized symptoms after the COVID-19 vaccine administration. CONCLUSION: The side-effects reported after receiving the Oxford-AstraZeneca vaccine (Covishield) are similar to those reported in clinical trials, demonstrating that the vaccines have a safe therapeutic window. Moreover, further research is needed to determine the efficacy of existing vaccines in preventing SARS-CoV-2 infections or after-infection hospitalization.

The pandemic, well-known as COVID-19, has been caused by the coronavirus SARS-CoV-2 and it has distinct characteristics from other coronavirus-related epidemics. This pandemic has been ravaging the whole world for more than a year now, and no drugs or vaccines have been found to eliminate this virus from the infected people effectively; only physical measures like social distancing, hand washing and face-mask wearing have been taken to reduce its spread and very recently Veklury (remdesivir) has been permitted by the USFDA to manage the critical patients. This disease can be asymptomatic, but when it is symptomatic, it presents with respiratory problems and cold- or flu-like symptoms, which can be diagnosed with a chest CT and confirmed with RT-PCR tests. In this review, the taxonomy and structure of SARS-CoV-2 and history, transmission, epidemiology, pathology, clinical features and impacts of the COVID-19 have been discussed. A summary of possible drug targets, attempted physical and chemical measures, as well as vaccine candidates, has also been provided. How this coronavirus is different from other coronaviruses, the obstacles in managing this disease and the possibility of a second wave have also been reviewed. This review represents a wide range of information regarding COVID-19 and intends to be used as a comprehensive overview in this regard.

At the end of 2019, a novel coronavirus (CoV) was found at the seafood market of Hubei province in Wuhan, China, and this virus was officially named coronavirus diseases 2019 (COVID-19) by World Health Organization (WHO). COVID-19 is mainly characterized by severe acute respiratory syndrome coronavirus-2 (SARS-CoV2) and creates public health concerns as well as significant threats to the economy around the world. Unfortunately, the pathogenesis of COVID-19 is unclear and there is no effective treatment of this newly life-threatening and devastating virus. Therefore, it is crucial to search for alternative methods that alleviate or inhibit the spread of COVID-19. In this review, we try to find out the etiology, epidemiology, symptoms as well as transmissions of this novel virus. We also summarize therapeutic interventions and suggest antiviral treatments, immune-enhancing candidates, general supplements, and CoV specific treatments that control replication and reproduction of SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV).
