I also am not getting it, though I do find it a tricky decision and considered it. I cornered my midwife until she would tell me what she REALLY thought about it, not just the CDC recommendations, and after we talked about it we came away with: 1. I've never gotten the flu in my life - I may be less predisposed than some would be. 2. I have no history of serious respiratory illnesses, which may make me a little safer were it to happen. 3. The flu shot makes so many of her clients sick, far more clients of course than actually get the flu naturally. 4. Given all this she recommends I keep doing whatever I normally do to stay healthy.
I would be more open to getting the flu shot if I didn't have a history of autoimmune conditions, which are of course related to gut health, and there is very murky understanding of vaccines' impact on gut health. I do think being pregnant and getting the flu can end up very dangerous, which is why I'd consider getting the vaccine if my midwife had had a neutral or supportive reaction to it.
My partner wants himself and my older son to get the flu shot to protect me and the baby. I'm not certain how I feel about it, for my son especially because he also has a history of gut issues. We did, however, decide to have our son vaccinated against pertussis to protect the baby. The flu shot just seems much more like a shot in the dark to me; every year the flu is different and it's a best guess whether the strain they choose is right.
