Dr. Fauci: ‘We Very Well May Need to Get Booster Shots’ After A Year or So to Maintain Covid Immunity


Dr. Anthony Fauci told MSNBC’s Mehdi Hasan that booster shots for the Covid-19 vaccine very well may be needed after about a year or so to maintain immunity against the virus.

Pfizer, the manufacturer of one of the three vaccines currently approved by the FDA for emergency use authorization (EUA) in the U.S., announced last week that testing had shown their vaccine to be effective for at least six months, said Hasan, asking Fauci what he expected would be needed regarding vaccine boosters.

“We need to be careful about that six month number,” said Fauci, noting that that time period was how long they had been able to study so far. “We know for sure it’s effective for six months and highly likely that it will be effective for considerably longer period of time,” he explained.

To know the real answer regarding the duration of immunity, said Fauci, it would be necessary to continue to study people in the months to come, regarding both their level of antibodies and if and when there were any new infections.

“So the good news is that it’s at least six months,” added Fauci. “Hopefully a lot more. But in direct answer to your question, if it turns out a year or a year and a half, we very well may need to get booster shots to keep up the level of protection.”
