I can't seem to find the answer to this. How long is the Tdap immunization good for adults? I had one either right before or after DD1, and remember not needing it when DS was born... But I can't remember if it's good for 3,5,6, or 10 years. Anyone know? TIA!
Re: Tdap for mom how long is it good?
Good to know, thanks!
A few months back there was something on the news about studies of the vaccine and how long this "newer" version of the whooping cough vaccine lasts ... something about the way they grow the vaccine or the strain they use.
this. ask them to run titers on your blood and see if its still in your system.
