That, is an opinion that has no basis either way in fact. If it were true, then no vaccine in the history of man or animal would have worked.
An effective vaccine will protect a person who receives it by lowering their chances of getting COVID-19 if they encounter the coronavirus. Widespread vaccination for the coronavirus means that the virus will not infect as many people. This will limit spread through communities.
Now that COVID-19 vaccines are authorized, here are the facts you need now.

Don't worry Jeanne. There already have been tens of thousands of Americans that willingly stepped forward and became those Phase 3 test Guinea pigs for you and, another 2 million plus since that, are quite happy to make sure it is safe for you to take.
As of July 30, 138,600 Americans had already stepped forward to be part of the testing (Moderna and Pfizer) and before the 2 currently used vaccines began being administered this month, & that number had increased by 60,000 in the J&J (Jansen) phase 3 trials.
Novavax is currently in Phase 3 trials with another 30,000 "guinea pigs' so you and others can feel more at ease.
America has always had a rather small % (approx 1%) that willingly stepped up for the rest of the country. 2020 is no exception.
"Nobody knows if the "immunity/antibodies" from the vaccine will be stronger or last longer than the "immunity/antibodies" one develops from contracting the virus."
One thing almost everyone (except a few way-out-there conspiracy theorists)
do know. The odds of either of the 2 current vaccines killing 346,500+ Americans is so low that it isn't even considered possible. That is how many have died chasing in-the-wild "herd immunity".
