Worth noting for whoever, significant report out today saying what may have been known at least somewhat.
J&J lasts longer. The mRNA vax fade to nothing far too fast. J&J has lower protection on day 1, but by day about 90, it exceeds Pfizer and Moderna in protection.
This is very important for any choices to boost. The previous boost analysis did not have as many months of fading to work with.
I would say it is prudent to not add any boost at this time.
Regardless of brand.
Prior to all the boosting, J&J was pretty clear that one shot is all that was needed.
