What does it mean to have a breakthrough infection?
- No vaccine is 100%. Some people will get breakthrough infections. However, for those who are vaccinated, those infections are mild or even without symptoms. So while the vaccine may not prevent all infections, it helps prevent you from becoming seriously ill or dying from COVID-19.
- This is similar to the influenza (flu) vaccine, which is much less effective than the COVID-19 vaccine at preventing breakthrough infections; but still protects against serious flu or death from the flu.
