Heres what to know about the risk of developing herpes zoster. Further analyses are needed to confirm this risk. Several studies have suggested a link between COVID-19 vaccines and the herpes zoster virusthe virus that causes shingles. Mild and infrequent HZ reactions may occur shortly after mRNA COVID-19 vaccination, at higher frequency than reported with influenza vaccination, especially in patients over 40 years old. Furthermore, we found a reduced risk of reporting HZ among under 40-year-old persons compared to older persons (reporting odds ratio 0.39, 95% CI 0.36–0.41). When compared to influenza vaccines, mRNA COVID-19 vaccines were associated with a significantly higher reporting of HZ (reporting odds ratio 1.9, 95% CI 1.8–2.1). To 30 June 2021, of 716 928 reports with mRNA COVID-19 vaccines, we found 7728 HZ cases. We performed disproportionality analyses (case/non-case statistical approach) to assess the relative risk of HZ reporting in mRNA COVID-19 vaccine recipients compared to influenza vaccine recipients and according to patient age. A shot of COVID-19 vaccine may cause herpes zoster in some recipients Researchers in Israel found six cases of shingles in patients who received a COVID-19 vaccine shot Herpes zoster is. We used the worldwide pharmacovigilance database VigiBase to describe HZ cases following mRNA COVID-19 vaccination. While the COVID-19 pandemic has led to an unprecedented race to develop a vaccine to protect against the. Several cases of herpes zoster (HZ) following mRNA COVID-19 vaccination (BNT162b2 and mRNA-1273) have been reported, and the first epidemiological evidence suggests an increased risk.

Antiviral treatments can reduce outbreaks of genital herpes, but they aren't a cure.
