Most frequent post-vaccination effects against SARS-COV-2 in workers of a Social Security hospital, Bellavista – 2021

Abstract

An effective measure to prevent and control infection by the new SARS-CoV-2 virus is the vaccine, and its adherence is essential. Objective: To determine the most frequent post-vaccination effects against SARS-CoV-2, in the workers of a social security hospital, Bellavista - 2021, considering the systemic and local dimensions. Material and methods: A descriptive, cross-sectional study with a non-experimental design. The non-probabilistic sample was 200 people. An instrument was used for data collection, the digital data sheet prepared by the authors, according to the characteristics sheet of the Shinopharm vaccine. Results: 60.5% (121 workers) presented systemic effect and 53% (106 workers) presented local effect. The frequent systemic effect was drowsiness in 39% (78 workers) and the frequent local effect was pain in the area of application in 49% (98 workers). Likewise, an association of systemic effects with age (p≤0.01) and sex (p≤0.01) was found; and local effects with age (p=0.01). There is no evidence of
association with those infected by covid-19, systemic (p=5.31) and local (p=0.23). Conclusions: Systemic effects are more frequent than local effects. The most common systemic effect is drowsiness and the most common local effect is pain at the application site. The systemic effect is associated with age and sex. The systemic and local effect is not associated with personnel with a history of infection with COVID-19.
