How Long Does Protection from the COVID Vaccine Last?
The protection provided by the COVID Vaccine is strong initially, but it can decrease over time, particularly against infection. Studies have shown that immunity from the COVID vaccine may start to wane after 6 months, especially against variants like Delta and Omicron. However, the protection against severe illness, hospitalization, and death remains robust for a longer period. As immunity naturally decreases, the likelihood of breakthrough infections increases, but these cases tend to be less severe compared to unvaccinated individuals.
To maintain optimal Protection, booster doses are recommended for eligible individuals. Booster shots have been shown to restore and enhance the immune response, increasing protection against new variants and reinforcing the effectiveness of the initial vaccination. The timing for booster doses varies based on the type of vaccine received and individual risk factors, so it is essential to follow current guidance from health authorities to ensure ongoing protection.
