I never even heard of Tdap. No one gets a flu vaccine, it is clinically proven to be useless. Covid jabs were designed for alpha and delta variants which don’t exist any more. RSV is rare and usually benign.
Tdap is what they use for tetanus vaccine these days.
Tdap is Tetanus, diphtheria and pertussis.
Pertussis is whooping cough which regularly kills or brain damages young infants. It is also a long illness lasting about 10 weeks unlike the common cold (7-10 days). It can take 2-3 months for the cough to fully resolve.
It is an illness you do not want to get or give.
RSV is also very hard on babies because their airways are so small the inflammatory response can suffucate them. My youngest spent a week in ICU at 6 months with it. They didn’t have a vaccine for it back then.
If my kids and/or their spouses ask me to get a Tdap or RSV vaccine for it, I’ll be getting it the next day. If they ask me to get a covid shot or flu shot, they can fly a kite.
