VERIFY: Length of immunity after getting COVID-19 vaccine remains unclear

Immunity from the flu shot only lasts a year, but it lasts a lifetime for the measles. So, how long will immunity last once you get the COVID-19 vaccine?

A KING 5 viewer contacted us with the question after she received an email from the Centers for Disease Control and Prevention (CDC) that gave a clear and understandably unsatisfying response: “Both this disease and the vaccine are new. We don’t know how long protection lasts for those who are vaccinated.”

To try and get more clarity, we checked with the CDC and Dr. Alex Greninger, the assistant director of the UW Medicine Clinical Virology Laboratory.

Greninger agreed with the CDC and told KING 5, “The tough thing here is longitudinal studies take time, right? These first vaccines, this is the first time we’ve ever done RNA vaccines in people. So that makes it harder to analogize.”
