The emerging COVID-19 variants are sparking more questions about our ability to protect against them, including whether existing coronavirus immunity works against them and how herd immunity could be diminished by mild or asymptomatic cases.
These are all questions that researchers are still gathering data on, but there are some directions in which initial studies are pointing.
While vaccine developers are looking into how much their vaccines protect against the known variants, existing immunity from prior infections is another important piece in the herd immunity puzzle.
So, how does having had the virus protect you from catching its variants in the future?
