The article I saw did NOT say that the vaccine CAUSED cancer. What it did say was that if you did have a cancer tumor or have cancer cells in your body, the vaccine might make it harder to eliminate those cancer cells.
I can not find this particular article again. I have looked at so many different ones.
“What it did say was that if you did have a cancer tumor or have cancer cells in your body, the vaccine might make it harder to eliminate those cancer cells.”
Of course that exact claim is refuted in the article. But you would have had to read more than the article title to see it.
