Abstract

Objective: to understand the frequency and type of adverse reactions developed by the population vaccinated in the community setting.
Method: a prospective observational quantitative study. The participants were those patients vaccinated at the Doctor Mendiguchia Carriche Primary Care Centre in Leganés (Madrid) during the vaccination period between May and September 2021.
The adverse reactions self-reported within the seven days after each dose of ComirnatyTM-Pfizer-BioNTech and the single dose of J&J® Janssen were analysed in the study.
Those reactions described as more frequent in the product specifications were collected, as well as unusual adverse reactions which patients associated with vaccination. Sociodemographic variables and past history of COVID-19 were also attached.
Results: the study included 821 patients; 687 of them received their first Pfizer dose, 457 received a second dose, and 100 received a single dose of J&J® Janssen. 88.5% of patients vaccinated with ComirnatyTM-Pfizer-BioNTech and 69.2% of patients vaccinated with J&J® Janssen presented some adverse reaction. There was a higher number of adverse reactions reported per patient after the second dose of ComirnatyTM-Pfizer-BioNTech. There was a relationship between the development of adverse reactions and age and gender. The percentages of unusual adverse reactions that patients associated with vaccination were also included.
Conclusion: the analysis of results provided important information about the frequency of adverse reactions in the different age groups, the different types of vaccines, and between those with or without a past history of COVID-19 The adverse reactions reported were numerous, but not severe.
