You are being pedantic......I think you know that you get injected with a liquid that's been made from a chemical formula - I hope that clears things up for you and you can enjoy the rest of your afternoon.
Good.
Now that we’ve established that, maybe we can go onto concepts like:
‘Randomised control trials’
‘Protective effect’
‘Odds ratio’
‘Number needed to treat’
And other such things that an entire sector of human endeavour uses to test vaccines?
