they only get their chicken pox vaccine at the one year visit so it may not have been enough time for the vaccine to be protective. the vaccine is not 100% either. there are many skin eruptions that can look like chicken pox but are really something else. i have no way of blinding diagnosing your child over the internet so consider seeing his medical provider so he can be properly examined and professionally diagnosed. chicken pox is responsible for many "false alarms" when it turns out the skin eruption is not chicken pox at all.
i think my 1 year old son has chicken pox. is up to date on all his shots & hasnt been exposed. is that possible?
