Also, vaccines are very specific to their target. If the target changes, the vaccines will lose effictiveness depending on how much the target has changed. For small changes the vaccine can still be quite effective, but for large changes the vaccine can lose much of their effectiveness or even completely. That's why flu shots are needed every year because the flu virus is continually mutating. The vaccines for Covid were created for the *original* strain of the virus ( version 1.0 if you will) and if you remember, they were EXTREMELY effective. It had almost ended the pandemic here in the US and also in Israel and other parts of the world. Masks were off and people were freely mingling without care or concern. Infection numbers had plumetted. Then the Delta variant came along later in the Spring which had sufficiently deviated from the original strain, so the vaccines could no longer target them properly. That's when a lot of the effectiveness in preventing spread was lost, but the vaccinated were still doing better than the non vaccinated while down with the virus. The argument that "we were promised Covid would go away if we got vaccinated but it's still here, therefore the vaccines are a failure" is a nice try from people who want to discredit the vaccines - but it doesn't fly. The vaccines succeeded spectacularly at what they were designed to do (target the original strain of Covid).. but then the goal posts moved and you can't blame the vaccines for not working.
I knew there would be variants and I’m sure no genius.
There will be variants of this virus, hell the original virus was a variant. And nice try but the vaccine was supposed to end the “pandemic”. That’s what was sold to the American people and it was B.S. Heck. CDC even had to redefine what a vaccine was!
Vaccine: “to prevent disease”. Originally. Now somehow it’s to lessen symptoms and prevent hospitalization.
Has there ever been an effective vaccine for a Covid virus?
Nope. And why not? Because the virus keeps mutating. But people in the government who knew(CDC and anyone with half a brain) ASSURED US THAT THIS WOULD END COVID. Full Stop. So the goal posts moved. No kidding.
I don’t blame the vaccines. I blame the virus. Which everyone with any training should have known from the start. And they did know. Which means only one thing. The American people were lied to.
