Implications and concerns.
Stuff we knew without this study.
Nothing at all saying any variant does escape immunity conferred by vaccine or being infected.
The authors speak to only testing for antibodies to the spike protein, then they say people who actually got COVID-19 have a lot of antibodies to yhe rest of the virus length.

What I got from this.... Are new vaccines able to be made from people who were ‘vaccinated’ and got kung flu or is that for people who naturally recovered?
