It will probably cause our resident hysterical anti-vaxxers to go into a tizzy but Moderna has in Phase 1 trial a neutralizing vaccine against RSV.
Conversely, I’ve never had the flu to my knowledge. I presume I have a natural immunity to it and have never gotten a flu shot. Nobody called me names or seemed to GAF because of it.
I also never got the mumps in the 1950s, even though my mom made me sleep in the same room as my brothers when they had it. Apparently I have a natural immunity to that as well. OTOH I’ve had bronchitis between 4-6 times in my life whereas most ppl never get it. So that’s obviously a chink in my immune system armor.
Bottom line is we’re all different and we should be left along to make healthcare choices that are right for us.
