ABSTRACT
Background: Older patients with cancer are at a higher risk of invasive infections. Vaccination is an effective approach to decrease the mortality and morbidity associated with infections. Objective(s): Our primary objective was to evaluate the proportion of older patients with cancer who had received routine vaccinations against pneumococcal, influenza, and coronavirus disease 2019 (COVID-19). Our secondary objective was to identify the factors associated with vaccine uptake such as age, sex, education, marital status, comorbidities, and place of residence. Material(s) and Method(s): This cross-sectional observational study was conducted in the geriatric oncology outpatient clinic of the Department of Medical Oncology at the Tata Memorial Hospital, a tertiary care cancer hospital in Mumbai, India, from February 2020 to January 2023. We included all patients aged >=60 years who were evaluated in the geriatric oncology clinic during the study period and for whom the immunization details were available. The uptake of COVID-19 vaccine was calculated from March 2021 onwards, which was when the COVID-19 vaccine became available to patients aged >=60 years in India. Result(s): We enrolled 1762 patients;1342 (76.2%) were male. The mean age was 68.4 (SD, 5.8) years;795 (45%) patients were from the west zone of India. Only 12 (0.68%) patients had received the pneumococcal vaccine, and 13 (0.7%) had received the influenza vaccine. At least one dose of the COVID-19 vaccine had been taken by 1302 of 1562 patients (83.3%). On univariate logistic regression, education, marital status, geographic zone of residence, and primary tumor site were correlated with the uptake of COVID-19 vaccine. Factors associated with a greater COVID-19 vaccine uptake included education (up to Std 10 and higher vs. less than Std 10: Odds Ratio [OR], 1.46;95% confidence interval [CI], 1.07-1.99;P = 0.018, and illiterate vs. less than Std 10: OR, 0.70;95% CI, 0.50-0.99;P = 0.041), marital status (unmarried vs. married: OR, 0.27;95% CI, 0.08-1.08;P = 0.046, and widow/widower vs. married: OR, 0.67;95% CI, 0.48-0.94;P = 0.017), lung and gastrointestinal vs. head-and-neck primary tumors (lung cancer vs. head-and-neck cancer: OR, 1.60;95% CI, 1.02-2.47;P = 0.038, and gastrointestinal vs.head-and-neck cancer: OR, 2.18;95% CI, 1.37-3.42;P < 0.001), and place of residence (west zone vs. central India: OR, 0.34;95% CI, 0.13-0.75;P = 0.015). Conclusion(s): Fewer than 1 in 100 older Indian patients with cancer receive routine immunization with influenza and pneumococcal vaccines. Hearteningly, the uptake of COVID-19 vaccination in older Indian patients with cancer is over 80%, possibly due to the global recognition of its importance during the pandemic. Similar measures as those used to increase the uptake of COVID-19 vaccines during the pandemic may be beneficial to increase the uptake of routine vaccinations.Copyright © 2023 Cancer Research, Statistics, and Treatment.
ABSTRACT
In the context of a pandemic of a new coronavirus infection, vaccine prophylaxis within the framework of the National Calendar of Preventive Vaccinations (NCPV) is an absolute priority in the fight against infectious diseases. The lecture presents the structure and features of the NCPV, the main directions of its improvement, information on the priority infections for vaccination. The strategy of immunization throughout life, which guarantees the creation of maximum protection against infections and preservation of the optimal level of health of people without age restrictions, is considered. Information is provided on approaches to vaccination of various patient populations against new coronavirus, pertussis, pneumococcal, and rotavirus infections. The presented lecture materials can be useful both to medical students and doctors of various specialties (infectious disease specialists, pediatricians, epidemiologists, bacteriologists).Copyright © 2022 by the authors.
ABSTRACT
Objective: An increased risk of invasive pneumococcal disease (IPD) has been reported in children with asthma before the introduction of pneumococcal vaccines (PVs). However, the evidence is limited after PV entered the routine immunization schedule. We aimed to investigate whether pediatric allergists recommend additional PV (aPV) to asthmatic children and if so whether there are any asthma-specific risk factors they consider. We also wanted to determine any changes in their recommendations during the COVID-19 pandemic. Material(s) and Method(s): A questionnaire was e-mailed to all members of the Academy of Pediatric Allergy and Asthma in Turkey. The questionnaire was filled online and consisted of 14 questions. Result(s): The questionnaire was e-mailed to 220 members. The response rate was 56.3% and 60.5% of PA recommended aPV. The most frequent asthma specific factors for aPV were severe asthma (70.2%), long term oral corticosteroid use (65.3%) and frequent exacerbations / hospitalizations (62.9%). COVID-19 pandemic increased the rate of questions asked to PA about aPV for asthmatic children compared to previous periods (75.8 vs 33.9%) (p<0.001) and %27 of PA changed their recommendations in favor of aPV during pandemic. Conclusion(s): Asthmatic children is not infrequent. Severe asthma and related factors seem to be the leading reasons to recommend aPV for asthmatic children. The aPV recommendation by PA is increased during COVID-19 pandemic.Copyright © 2022 Bilimsel Tip Yayinevi. All rights reserved.
