An observational study explored adverse events after vaccination. Participants were invited to complete an electronic survey, capturing self-reported COVID-19 symptoms, PCR/antibody results, and Adverse Events (AEs) following first dose of BNT162b2/Pfizer vaccine. Understanding AEs associated with SARS-CoV-2 vaccination has public health implications, especially with regard to vaccine hesitancy.
Prior to COVID-19 infection but not ongoing, Long-COVID symptoms were associated with an increase in the risk of self-reported adverse events following BNT162b2/Pfizer vaccination. COVID-19 illness-vaccination interval did not significantly influence AEs. In a survey-based observational study, healthcare workers in the United Kingdom reported AEs experienced after their first dose of BNT162b2/Pfizer vaccine. Duration since COVID-19 infection did not affect severity of AEs.
Even in the best-case scenario, vaccines are not a perfect science, there are many times where vaccines are not as effective as hoped and where adverse events are reported. That said, the COVID-19 vaccine has, and continues to save lives. If you haven’t already been vaccinated, consider getting the shot. If you know others who are hesitant, encourage them. Let’s see this pandemic come to an end once and for all! Stay well, mask up indoors and stay tuned!
