rotavirus vaccine has been offered as a new free vaccine by the Goverment of Ontario since Auguest 2011.
it provides protection for young babies from getting the rotavirus infection which causes severe vomitting, diahherea and dehydration. the best time to give is at age of 2 months and 4 months. the lastest age to receive the first oral dose is at the age of 20 wks and complete the second dose at 24 wks.
many physicans run out of the vaccine, that's why your doctor may suggest you to purchase it on your own if you really want to give your baby the vaccine.
since this is the a fairly new immunization schedule, your baby's immunization record(the yellow sheet) does not have it.
