Oo, normal lang yan! A few of us here had babies na nag-fever after their rota vaccine, it's one of the common side effects, usually mild at 1-2 days lang. Just monitor baby's temp at make sure siya's comfortable, hydrated, at may enough rest, pero if the fever's really high or hindi bumaba after 48 hours, or kung worried ka talaga, better to check with your pedia para peace of mind lang. Most of the time it passes quickly and it just means baby's body is responding to the vaccine.
