Abstract:

Routine immunizations during pandemics can be harmed; this study estimated the influenza vaccination coverage in the elderly during the COVID-19 through the EPICOVID-19, a population study conducted in 133 citiesthe 26 Brazilian states and Federal District. We ed 25 census tracts with probability proportional to the size of the tract, 10 households by census tracts and one random person interviewed; 8,262 elderly (≥60 years old) were interviewed and asked whether they had had a flu vaccine in 2020. Vaccination coverage was 82.3% (CI95%=80.1; 84.2) with no difference by sex, age, and region; higher vaccination coverage was observed in the richest (84.7% versus 80.1% in the poorest), and among those with higher schooling (87.3% versus 83.2% less schooling); lower coverage among indigenous (56.9% versus > 80% among other ethnic groups). Positive association existed with number of comorbidities for men, but not for women. Most of those vaccinated (97.5%) received the vaccine in the public health system. The private was chosen mostly in the South region, by the rich and by those with more schooling. Vaccination coverage was seven percentage points lower than the government target (90%), and inequalities should be reverted in future campaigns.
