One cloud over vaccinations is the poor results in immunocompromised people. A lot of these people are not making antibodies in response to the vaccine. A number of breakthrough cases have occurred in this group. As we know, chronically infected people can have mutating virus that can produce viable variants, as occurred in Britain.
Some people in the long COVID support groups that were negative for antibodies after infection are finding they are still negative after completing the vaccines and waiting several weeks before being tested. They may not be protected from reinfection.
It does appear that some people fight the virus with T cells and never develop antibodies. A lot of unknowns still.
Just the presence of such folks in our society argues - once again - for the REST of us being vaccinated. Think of the life we might save beyond our own. End of sermon, so YMMV.
