YANKTON, S.D.(WNAX)- There are some debates, mostly online, about the benefits of natural immunity to Covid-19 as opposed to vaccine immunity.

Liz Healy, infection control specialist at Avera Sacred Heart Hospital in Yankton, says natural immunity has a broad definition.

Healy says those that have had Covid-19 may not be as protected from another round as they believe.

Healy says Covid-19 is different than other diseases.

Healy says the science points to the effectiveness of vaccination over any natural immunity.
