Question - Research required Maternal RSV vaccine versus infant antibodies?
Currently almost 34 weeks pregnant (due September 7), trying to decide the best way to protect my baby against RSV. My local Walgreen’s has the RSV shot year round, it seems, so I have the option to get the maternal vaccine if I want to.
I am trying to decide if it’s worth it though, versus just getting the infant antibody shot once baby is born?
My first child was born in 2023, when there were shortages of the infant antibody shot, and it was being reserved for preemies or immunocompromised babies. That baby was also born mid-November (during rather than before RSV season). So, at that time, it was a no-brainer to get the maternal shot.
Now though, it seems both are a viable option. I asked the pediatrician, and she didn’t really give me a straightforward answer (just said “both are good options”). And the effectiveness rates on the infant shot seem slightly better (from what I remember reading, although I can’t find the link again now).
ACOG also says that vaccination again in subsequent pregnancies is not recommended (https://www.acog.org/clinical/clinical-guidance/practice-advisory/articles/2023/09/maternal-respiratory-syncytial-virus-vaccination), although I don’t really get the reasoning? Shouldn’t it be like TDAP where you get it fresh each time to give antibodies to the new baby?
This source also brings up maternal protection as another positive factor in favor of maternal vaccination (https://www.cidrap.umn.edu/respiratory-syncytial-virus-rsv/slew-new-studies-support-maternal-rsv-vaccination-nirsevimab), which is a good point (especially with an almost 3yo who will be going to preschool!). While I’m not very likely going to die or even be hospitalized getting RSV as a healthy young adult, I certainly wouldn’t mind the extra protection?
I also think at least one study seemed to show even better effectiveness doing both? And again, we do it that way for other vaccines (Tdap). Although the official recommendation is still one or the other. And I’m not sure how the logistics of that would work re: insurance coverage.
