Is 4 months the magic number when all the vaccine problems suddenly appear? If I had said February 2020 for the first doses, would the question be “no children over five months old?”
There were probably a small number of women in early trials who were pregnant when they got their first dose, but certainly not enough to use as a representative data set. As with any new medicine, it will take time to get a more complete picture of every possible combination of individual situations, timings, etc. As of right now, there is no indication of any problem related to fertility, pregnancy, or child development. The only known problem is with the stabilizing agent for the lipid shell in the Moderna and Pfizer vaccines, which can very rarely cause a severe allergic reaction in sensitive individuals (about 1 in 90,000 for Pfizer and 1 in 400,000 for Moderna). This is known and documented, and it’s the reason you have to sit for 15 minutes after receiving either vaccine.
What is the stabilizing agent in the Pfizer and moderna vaccines?
No, so the oldest babies are 4 months old.
