A large study conducted by Pfizer and BioNTech found that the vaccine was more than 90% effective at preventing symptomatic COVID-19 infection, and more than 95% effective at preventing severe illness, hospitalization, and death, up to 6 months after the second dose.

It’s important to note that immunity can wane over time, and people may need booster doses of the vaccine to maintain protection. The Centers for Disease Control and Prevention (CDC) recommends that people who have been fully vaccinated continue to follow guidance to protect themselves and others, including wearing masks, practicing physical distancing and avoiding large gatherings.

It’s also worth noting that the protection provided by the COVID-19 vaccine is still being studied, and the duration of immunity may change as new information becomes available. The CDC, the World Health Organization (WHO) and other health authorities will continue to monitor the situation and provide updated guidance as more data become available.
