The shots have been reported to have Herpes as a side effect. Shingles is the same virus category.
A new study is getting plenty of attention after researchers linked a particular form of herpes to the COVID-19 vaccine in a handful of people.
The study, published in the journal Rheumatology, analyzed side effect data from 491 people with autoimmune inflammatory rheumatic diseases (AIIRD) who received the Pfizer-BioNTech vaccine.
The researchers found that six of the patients with AIIRD (or 1.2%) developed herpes zoster—aka shingles—within several days of receiving the vaccine. Four of the patients had rheumatoid arthritis, one had Sjogren's syndrome, and another had a connective disease. All of the patients were women, and five of the reactions happened after the first vaccine dose.
