<s>[INST] Hi Dr, my baby is pre mature, she was born in the 7th month. My doctor told me to get her for polio drops & BCG & hepytitus injections once she is 2 kg. Yesterday she weighted  235grms. Dr gave her polio drops & hepytitus injection. He said BCG will be given on this Tuesday. Today after both her feeds she vomited twice. plz advice is it serious & need to rush to the dr or this happens to all babies after the polio & hepytitus doses. Looking froward to hear from you. Thanks. [/INST] Thanks for asking the query,This is side effect of the vaccination given to your child.I would suggest you to take the child to child specialist so that an antiemetic can be given.Give her fluids as chances of dehydration are more.Hope you find this as helpful,Regards.. </s>
