“What Immunity to COVID-19 Really Means”
- see https://www.scientificamerican.com/article/what-immunity-to-covid-19-really-means/
I’ve been telling folks for a while that coronaviruses have a sketchy record of conferring long term immunity, and that betting major public health policies on “herd immunity” or a non-existent vaccine is a gamble that we could lose. We really need this bug to produce at least 2 years of immunity, but I can’t begin to put odds on the likelihood of that. We just don’t know.
If there is no immunity, maybe this is the catalyst to finally get people to take their diet, health and fitness more seriously. It’s just so much easier to get a vaccine and stuff ourselves with carbs...
