I think it’s like an EA that has a portfolio with two logics.
There are two entry points, and it may be possible to counter the mutation of the virus.
Perhaps even if spike protein becomes Mers virus, it may work.
When given in combination with a Pfizer vaccine, my T-type immune cells will learn three targets.
I don’t know which portfolio has the best risk-reward ratio at the moment, but think there is a way to counter the mutant virus.
