What is an instant and clear analogy to use when any vaxxer tells you the virus ''isn't as lethal/contaminable when you got your shots and booster(s)''
By way of clearing up that even if that is indisuptable, that nobody can foresee protential l(at leas long-term) catastrophic consequences, that injecting your body with this experimental invention created under pressure, can be so much more and worse than whatever benefits are proposed. ?
I just need it to be quick and to the point
i can't go into discussion every time with these people blindly putting their trust in this highly unfamilliar situation
