Adverse Effects With COVID-19 Vaccines Are Mild, Short-Lived
In a recent publication in The Lancet Infectious Diseases, researchers conducted an observational study and analyzed data reported to the Vaccine Adverse Event Reporting System and v-safe.

Waning Effectiveness After Third COVID-19 Vaccine Dose
Findings from a new study reveals that immunity against severe COVID-19 disease starts to wane 4 months after receipt of the third dose of an mRNA vaccine. Waning immunity was detected during both the Delta and Omicron variant waves in comparable fashion to how mRNA vaccine effectiveness wanes after a second dose. Learn more about what the data revealed in this study.
