That's what they say it is intended to do now. That was not what they were saying initially. Remember they were supposed to by 95% effective, they could stop transmission, etc. When all of those lies where debunked, they changed their tune and now they claim they will make the virus less severe and prevent long covid. But again, I've not seen a lot of data to substantiate those claims either.
I believe the way the covid vaccine was handled, will damage the CDC's credibility for years and put doubt in peoples minds about all vaccines going forward. Our Son was asked by a doctor if he wanted our grandchild to get his vaccines! I'm sorry but there have always been a small percentage of anti vaccers, but I've never had a Dr. ask if we wanted to give a baby their vaccines. That tells you what his patients are saying to him.......
