There is probably a knee-jerk reaction in FR to jump towards covid, but this is the first 3 months of the baby’s life and it is those other illnesses that are far more dangerous in that time period then covid.
There were no covid deaths to speak of below age 65. Now infants in the first 3 months could be a difference configuration, but best not to dwell on that because this is not about covid. This is about most particularly diphtheria which is in the Tdap vax. Diphtheria destroyed entire villages of infants in England in the 1800s.
The problem is that the standard vaccination schedule for newborns does not have them protected until after 3 months.
The bottom line here is that evaluating the norms should just reject covid in the package of threats. It’s possible that her family members maybe willing to get some of those other vaccinations. But in an overall sense the correct way to handle this is simply have that child do the initial 3 months vaccination schedule and then have the family come see it
I hope the mother is planning to breastfeed exclusively for the first 3-6 months. That’s the best way to protect her baby naturally.
My daughter is having a little baby boy her first at age 37, my wife and I both got the Tdap at the local pharmacy, I didn’t even know what a Tdap was, it was no big deal to me after it was explained. The in-laws are not getting a Tdap and will wait three months to see the baby, but they live in Arizona and we live in Texas and it is only a 3 hour drive for us, shot is good for 10 years.
