question: Hello doctor, My twin daughters, age is 17years. One of them got the first blister of chicken pox and totally she got 30-40 blisters a few on back, hands, scalp, chest and 4-5 blisters on forehead. Now since yesterday, they have formed a scab. Second twin got the first blister on the chest five days later, and the second blister after that, a total of two blisters and till now no scab is formed. They both got vaccination when they were small. My question is whether the second twin who got only two blisters, has she got enough antibodies of chicken pox so that she is safe not to get it again in the near future?
