Dear Dr. Bob,
We just went to a new pediatrician today and she advised giving the polio vaccine to my 18 month old at this visit do to the fact that we bring him to pools to swim. She said that polio could be passed through the water if someone was 'shedding' after a visit to a country with active polio cases. I am concerned about this and had never heard of this before. How likely is this? I would have thought that all of the chlorine and other chemicals in pools would kill bacteria/viruses?
We did get the vaccine at this visit and the varicella vaccine too but didn't get DTAP at this time. Until now, we have been following your alternative schedule. Should I make a special visit back for DTAP or just get it with the flu vaccine in Oct or at the 2 year visit in Nov (when he would have had the polio vaccine that he got today)?
FYI-my son actually had a **likely*** case of whooping cough last summer (about 8 months old) despite being immunized. I say likely because the culture was negative but he had all of the symptoms. The health dept and our pediatrician both diagnosed whooping cough and said that the culture wasn't reliable after about 3 weeks-which it was.
Thank you for reading,
