"Infections after vaccination are still uncommon. They're approximately 2% of people who are vaccinated," said Dr. Sabrina Assoumou, an infectious disease specialist at Boston Medical Center.
Almost as rare are people who get the virus, recover, then get it again.
A recent CDC study of COVID reinfections looked at 1,572 patients. Forty became reinfected, for a rate of 2.5%.

Can you get infected with Omicron after having a previous variant of COVID-19?
?Yes, it?s definitely possible,? says Thomas Russo, M.D., professor and chief of infectious disease at the University at Buffalo in New York.
The
CDC says that people who have been vaccinated against SARS-CoV-2, the virus that causes COVID-19, and those who have actually had the virus have a ?low risk of subsequent infection? for at least six months. Meaning, you should be protected for six months after having COVID-19. Beyond that, though, it?s hard to say.
In fact, recent research from the Imperial College London found that the risk of reinfection with Omicron is 5.4 times higher than it was with Delta, the previous dominant COVID-19 strain. Researchers specifically found that protection against reinfection by Omicron from a past COVID-19 infection could be as low as 19%.
?One of the key features of Omicron is that it?s much more resistant to immunity, whether vaccine-induced or caused by previous infection,? Dr. Russo says.

More reasons to get vaccinated even if you've had it. In fact, unless you maintain the vaccines are either completely ineffective, or actually harmful to you, you should still get them, as they'll provide some additional protection from reinfection or severe infection even if you have it, and something is better than nothing.
Given that the number of new cases in the US has been well over 500,000 PER DAY for the last 20 days, and the moving avg. has been over 800,000 cases/day more recently... that's millions of cases.
If the reinfection rate is 2.5% among the unvaccinated as the study above revealed, that's 25,000 new cases per million, at a time when hospitals are already all backed up.
