New research published by the New England Journal of Medicine suggests people who are vaccinated but get infected with COVID-19 are less likely to pass the virus along to others.The study found that vaccinated people who got infected, cleared the virus out of their bodies in about five and half days, while it took unvaccinated people nearly eight days. "Our vaccines are highly effective,” said internal medicine physician Dr. Aftab Khan.Khan says that's because the antibodies from the vaccines fight the virus off."When you're vaccinated, obviously, when the virus attacks you, you attack back with multiple antibodies. If you're unvaccinated, you're going to carry this virus for a long period of time. Especially people who are immunocompromised. They will carry this virus not for seven days or 10 days, they will carry this virus for months,” Khan said. Along with getting rid of the virus faster, he says the vaccines are better protecting people from the new omicron variant and boosters are significantly increasing effectiveness."With the booster shot, I think the effectiveness can go up to 95 percent for any variant existing at this time,” Khan said.However, the more the virus spreads, the more chances it has to mutate. And if more mutations are created, Khan says it is possible we reach a point where new vaccines would have to be developed.Khan says monoclonal antibody treatments can also reduce the amount of time the virus stays in your body.He says the treatments are being underutilized and recommends them for those who are immunocompromised.
