Factores asociados con la aceptación de la vacuna contra SARS-CoV-2 en embarazadas peruanas, 2022

OBJECTIVE: We describe the acceptance of the SARS-CoV-2 vaccine in Peruvian pregnant women and associated factors during 2022. METHODS: Observational, analytical, cross-sectional and retrospective study with a sample of 315 pregnant women selected by simple random sampling, January to June 2022. RESULTS: The acceptance rate of the SARS-CoV-2 vaccine was 58.1%. Of the total number of immunized women, 96.2% had two doses and 3.8% had only one dose; the main reason for having only one dose was having been ill with COVID-19 and one dose was sufficient (42.8%) while the main reason for not having any dose was the fear that the vaccine would harm the baby (40.1%). Regarding associated factors dependent work obtained a Prevalence Ratio (Rp= 2.18) CI95% [1.13-4.18; p=0.019] and previous SARS-CoV-22 infection an Rp= 2.41 CI95% [1.03-5.59; p=0.040]. CONCLUSION: more than one third of pregnant women did not accept vaccination against SARS-CoV-2; factors associated with acceptance of vaccination against COVID-19 were a history of SARS-CoV-2 infection and performing dependent work.
