ROCHESTER, N.Y. (WHEC) — As more people get vaccinated for COVID-19, many are wondering how long protection against the virus lasts.
Dr. David Topham is an expert on immunology and infectious diseases at the University of Rochester Medical Center.
He says while it's still too soon to know how long a vaccine will last with certainty, scientists can make an educated guess.
Topham says all signs point to protection for potentially two to three years or longer, and boosters would likely target specific variants.
This takes into account that the Pfizer and Moderna shots are more than 90% effective six months after the second dose.
