The problem for RFK is that this is almost certain to be a losing proposition, politically. Trump knows this. Running on an anti-vaxx message in a country where something like 85% of the adult population has been vaccinated isn’t going to be a successful strategy.

Bottome line, do not get more Covid jabs, use good nutrition information to enhance your immune system and protect from serious illness.
