Hi, we have given the 2.5month time vaccination to my son at the government hospital on Tuesday and he had fever and pain but that is gone now. But I can see that he is not taking proper feeding which he used to take before that. The first day he used to have a vomiting sensation as well and vomited once. The first month vaccine we had given and private hospital, so it there any change because of that??? And when can I expect that he will start taking food feeding again??
