True to a degree, we and they ( doctors) are realizing the vaccine dose not stop you
from getting or transmitting covid, this is more like a treatment than a vaccine.
It does lessen the affects and greatly lowers the odds of death or hospital stays, but does not guarantee
that either.
True Vaccines stop disease, what we are getting slows it down and is not permanent.
they are learning every day and in big picture still early days as far as viruses go.
New variant seems to married with cold sypmtons, which makes it far more contagious
but far less nasty in its affects. Also new variant seems to build natural immunity
once you have had, better than vaccines.
But again early days and only more time, testing and science will teach us.
They are many believe to many shots could lower the ability to gain natural
immunity if you get covid, so tough decisions and still much to learn.
this is ever changing and ever evolving, many things could change yet,
long way to go IMO.
