A member asked:

Is it possible for a toddler to get whooping cough if he's been immunized?

A doctor has provided 1 answer

It's rare-: But not impossible. The vaccine is 96-99 % effective, but that still means 1 or 2 in 100 may not build up good antibody levels. If there is concern he has pertussis, cultures can be done. If the concern is did he build up immunity, then a blood test can be done to see if he is indeed immune. That test is not cheap, but if significant concern, then is warranted.
