4 Month and Hep A

Hello everyone. I am a first time mom, so I am incredibly sorry if this sounds stupid because I do not know.. but I was wondering if young babies can get hep A? I currently live in California and there has been an outbreak of hep A. We live relatively close to the cities with outbreaks and were going to visit one of these cities soon. My baby is almost 4 months old, but I read that they do not receive the vaccine until at least they are 12 months old. I am worried because I do not know what to do in this situation. Help please?
