Summary
Herpes zoster ophthalmicus (HZO) and herpes simplex ophthalmicus (HSO) are rare following SARS-CoV-2 vaccination. While a slightly higher risk of HZO was observed with the BNT162b2 vaccine, further research is needed to understand the mechanisms.
Area of Science:
- Ophthalmology
- Vaccinology
- Infectious Diseases
Background:
- Ophthalmic complications following SARS-CoV-2 vaccination, specifically herpes simplex ophthalmicus (HSO) and herpes zoster ophthalmicus (HZO), require thorough investigation.
- Understanding the incidence and clinical presentation of HSO and HZO post-vaccination is crucial for patient safety and vaccine surveillance.
Purpose of the Study:
- To evaluate the occurrence of herpes simplex ophthalmicus (HSO) and herpes zoster ophthalmicus (HZO) after SARS-CoV-2 vaccination.
- To analyze the clinical presentations and identify potential associations between vaccine types and ophthalmic outcomes.
Main Methods:
- Retrospective analysis of 1180 cases of HZO and HSO reported to the CDC VAERS between December 2020 and July 2022.
- Inclusion of patients vaccinated with BNT162b2, mRNA-1273, or Ad26.COV2.S, with descriptive analysis and statistical tests (ANOVA, Chi-squared, Kaplan-Meier) to assess associations.
Main Results:
- A total of 1180 cases (983 HZO, 180 HSO) were reported, with most cases occurring in women and after the first vaccine dose, predominantly within two weeks post-vaccination.
- The BNT162b2 vaccine was associated with the highest number of reported HZO and HSO cases.
- A significantly shorter onset interval for HZO was observed with BNT162b2, and a higher 30-day risk of HZO was noted compared to other vaccines.
Conclusions:
- Herpes simplex ophthalmicus and herpes zoster ophthalmicus are rare adverse events following SARS-CoV-2 vaccination.
- The study suggests a potential temporal association and a slightly elevated risk of HZO with the BNT162b2 vaccine.
- Further research is warranted to elucidate the immunological mechanisms underlying these ophthalmic conditions post-vaccination.
