re: Johnson & Johnson 1 shot vaccine shows 66% efficacy, 85% v severe disease

I know it will take awhile to study but I am very interested to see what happens when vaccines are given to people who already have some natural immunity due to a previous infection.

Those individuals have a stronger immune response to the vaccine according to the personnel who have me my Covid-19 shot yesterday. Since the immune system is already primed it acts much like how others respond to the 2and dose.

The amateur scientist in me thinks it would boost efficiency but this area certainly isn't in my wheelhouse.

Regular exposure is what keeps the immune system primed to respond. So getting it, then getting the vaccine isn't hurting anyone.
