U of M researchers studying long-term immunity for COVID-19

Kare11 7-21Dr. Marc Jenkins, sat down on 7/25/2021 for an extended interview with Chris Hrapsky from Kare11 news to talk about all things COVID19.

Four new studies are helping to answer just how protected people are after a coronavirus infection and how potent a vaccine can be after infection. The research shows good evidence that natural immunity lasts at least a year and could last much longer, according to experts, but it’s unclear if the protection is enough to neutralize several variants of the SARS-CoV-2 virus. Dr. Jenkins and Mr. Hrapsky sit down to discuss these findings and more.
