Plus: Pfizer did not know whether Covid vaccine stopped transmission before rollout.
Someone on Twitter was telling me exactly that. Vaccine safe and effective and we all know that they have not tested the effect of how well it cut down transmission so everyone was told to wear mask.
Duh dude, if that were true, then why take the jab? It's like telling someone here is a mushroom, but we don't know how it will react to you. No wonder those zombies all wear masks even with injection.
