Are covid jabs useless?

Maybe it's more about your DDs immune system than the vaccinations? Millions of us have had the vaccinations and avoided either Covid completely or had very mild doses of it. I had but had no symptoms, my DS has had it four times each time with less severe symptoms. We all have very different immune systems so react differently to the infection and the immunisation.

Well, death rates are nothing like they were, so I suppose you have to trust that things could be a lot worse for your daughter in law if she wasnt vaccinated.
