چکیده

CONTEXT: India experienced pandemic phase of H1N1 in May 2009 to December 2010. Thepostpandemic phase went on from January 2011 to December 2014. As per the WHO, all countriesshould immunize their health‑care workers as a first priority to protect the essential health infrastructure.AIMS: The aim of the study is to assess the level of awareness and acceptance of influenza vaccineamong physicians and also the perception of physicians regarding H1N1 infection. This study alsoexamined time of vaccine administration in relation with efficacy concerns based on literature.SETTINGS AND DESIGN: A vaccination campaign was conducted for all health‑care workers ofSeth GSMC and KEM Hospital, Mumbai, in the month of July 2017 based on which a cross‑sectionalobservational study was conducted among the physicians of the same institute.METHODS: After ethical clearance, a prevalidated pretested survey based on a pilot survey of 20physicians was distributed among physicians, which was based on the awareness and acceptance ofH1N1 vaccination among physicians and perception of H1N1 infection. Effective sample size was 272.STATISTICAL ANALYSIS USED: Descriptive statistics and Chi‑square test were generated forthe survey responses. All the continuous variables were reported as mean, median, and range.Categorical variables were reported as tables and pie charts. P < 0.05 was taken as significant. Dataanalysis was done with SPSS version 21.RESULTS: The overall vaccine compliance was 29.8%. This study has found that area of work,deficiency in knowledge about adverse effect of vaccine, misconceptions regarding vaccine, andconcerns about efficacy and duration of vaccine are the important factors which lead to decreasedvaccine compliance. Furthermore, it is found during the study that timing of vaccination was not givendue importance as considering the epidemiological pattern.CONCLUSIONS: More emphasis should be given to education sessions and counseling of physiciansregarding H1N1 vaccination and oseltamivir therapy. At administrative level, more focus should begiven on timing of vaccination and other logistics. Vaccine campaigns should be conducted ideally1 month before expected rise in cases. Quadrivalent vaccine would be more appropriate over trivalentbased on epidemiology of infection in India.
