Patient's question:
Hello: My baby is now 5 and a half months old. We have finished the three (polio drops). However, I recently learned that half an hour before taking the drops, the baby cannot be fed milk. But when my baby took the first and second drops, he was given the drops 5-10 minutes after finishing feeding. I would like to know if this affects the effectiveness of the drops, whether it is necessary to repeat the dose, and if repeating the dose will have any impact on the baby's health? I urgently need an answer. Thank you!Doctor's answer:
Do not breastfeed for 1 hour before and within 30 minutes after taking the sugar. The is a live attenuated polio vaccine, which stimulates the production of antibodies in children to resist the poliovirus. However, the efficacy of the is related to temperature, as it survives best and is most easily absorbed by the intestinal mucosa at 20-22℃. Breast milk temperature is 37℃, which can easily render the ingested live vaccine ineffective. Sugar should not be used 1 hour before breastfeeding because breast milk may contain antibodies against the virus, which can deactivate the vaccine and reduce its efficacy.
