Introduction: Currently the only tool we have against COVID-19 are vaccines. In this study we will use the vaccines developed by BioNTech-Pfizer (Comirnaty) and Moderna (Spikevax), and we will carry out an analysis of the side effects they produced by them. The objective of this study is to identify new side effects caused by the aforementioned vaccines among health professionals at the Lozano Blesa University Clinical Hospital in Zaragoza vaccinated from January 16, 2021 to the present, as well as to identify those side effects not included in the leaflets.
Method: Retrospective observational study after administration of the 2nd dose of the vaccine in all health professionals. An anonymous and voluntary questionnaire was conducted asking about side effects after the first and second dose. Data analysis was carried out with the Chi-Square statistical test.
Results: The percentages were obtained: lymphadenopathy 96.4%, dysthermic sensation and chills 96.3%, fever 94.4%, headaches with 90.9%, asthenia 88%, myalgias with 74.4% of the total , others described 3.62%.
Conclusions: Those vaccinated with Moderna presented more symptoms; the necessary values were not reached to determine that there is a statistically significant association in this regard. The symptoms experienced, in a sample that can be extrapolated to the general population, correspond almost entirely to those reflected in the technical specifications of the vaccines developed. It is worth mentioning that the data collected on alterations in menstrual cycles, breastfeeding, or Priapism are symptoms that had not been initially described in the vaccine technical sheets.
