Do the Covid vaccines provide long-lasting protection?

Summary

The CDC now recommends a second dose of the 2024-25 Covid vaccine for high-risk groups, including those over 65 and with weakened immune systems, six months after their first dose.

Experts, such as Dr. Ashish Jha and immunologists Akiko Iwasaki and E. John Wherry, support this guidance, highlighting that while the mRNA vaccines from Pfizer and Moderna are effective, the virus’s rapid mutation and year-round presence necessitate more frequent boosters for at-risk populations.
