It looks like COVID-19 booster shots could become widely available as soon as next month.
US health officials are now recommending booster shots eight months after your second dose of the vaccine.
Dr. Ben Neuman, a virologist at Texas A&M, compares the COVID vaccine to the polio vaccine. He says if history repeats itself, in time people could be totally vaccinated against COVID-19.
"It looks as though this thing works about as well as one of the most successful vaccines that humans have ever developed," Dr. Neuman says. "I would expect it's probably going to be real similar [to the Polio vaccine], and you're probably going to end up with maybe four doses."
In a statement, federal health officials say the Biden Administration is prepared to start offering booster shots on September 20th.
If that's the case, Dr. Neuman says you should be prepared for a big rush of people trying to get appointments, similar to earlier this year when the vaccines were first made available.
"I think the ones that are vaccinated would probably want the chance to get … stronger protection," Dr. Neuman says. "Even that 90 percent leaves 10 percent who have had the vaccine and are totally vulnerable. And that's not a good feeling."
