Healthcare workers who have recovered from COVID-19, except those with Long-COVID, reported adverse reactions following their first dose of the Pfizer/BioNTech vaccine more often than those who had not been infected, according to a recent study.
Researchers in the United Kingdom surveyed more than 900 healthcare workers in three hospitals in a longitudinal observational study, and about 265 of the participants (30 with Long-COVID) were infected with the CCP virus prior to getting the Pfizer/BioNTech vaccine.
