My baby boy is 2 mnth old. He got his 1st vaccination on 18 march in both legs. Now we see that from the day he got vaccine his leg shivers 6-7 times daily for 10-20 seconds. What might be the reason.

A. the side effects of vaccination can remain for only two or three days and after that also if the problem continues it is advisable to get the child examine by the doctor and also at the same time rule out calcium deficiency which can lead to such problems
