- On Health Watch tonight, people who have been infected with the coronavirus may continue to make antibodies to the virus for the most of their lives. Dr. Mallika Marshall joins us now. And Dr. This comes from a new study that was published in Nature. What about people though who are vaccinated? Do they get the same thing?

MALLIKA MARSHALL: Yeah, they probably do as well, but they may be more vulnerable to variants. These were researchers at Wash U in St. Louis that looked at 77 people who had recovered from mostly mild COVID-19. And they identified these antibody producing cells that are living in the bone marrow that can continue to produce antibodies for years. They also found that there's early evidence that vaccination can trigger the production of those same cells. But like I said, there is concern that the emerging variants might blunt some of that response. So booster shots will likely be necessary for most of us but people who've had COVID and have been vaccinated probably enjoy longer lasting protection.
