Dr. Elizabeth Hudson, regional head of infectious diseases at Kaiser Permanente, joined Eyewitness News to talk about the vaccine and answered a question from a viewer who wanted to know if seniors who were vaccinated in February will need a shot. reinforcement in the fall.
Dr. Hudson said that even though we only have six months of data on vaccines, as it is the time we use them, it’s hard to say.
“But day by day, we know more and more, and it looks like the response and protection of these vaccines against COVID will be lasting,” he said. “I think at least a year and probably more, but with all the COVID, time will tell.”
New research published in the New England Journal of Medicine this week suggests that protection against the Modern vaccine lasts at least six months. This report echoes what Pfizer said a week earlier about its vaccine, which works similarly.
Both reports were based on follow-up tests on dozens of people who received the shots during studies that led to the use of the vaccines. These studies were done before new variants or versions of the coronavirus appeared and began to spread.
