The thing is, the 'science' keeps changing. At first the 'science' told us it wasn't communicable from animals to humans. Then that distance would be the answer. Then masks. Then if you got the vax, no mask. Then masks again. Now the vax needs a booster....already. No problem with science, but none of this seems very conclusive.
This has always bothered me. The vax is supposed to lessen the symptoms but does not prevent becoming positive. You can just as easily be positive and spread it to others even if you have the vaccine. You might stay out of the hospital, but stats show that the vast majority of people with symptoms have at least one and most have 2 co-morbidities....so overall health is apparently a big factor in how serious symptoms are whether someone is vaxed or not.
I'm not anti-vax, but the whole, "I got it to protect my friends and family" is quite the reach.
