Does the chicken pox vaccine confer lifelong immunity?

Does the chicken pox vaccine confer lifelong immunity?

Possibly: Introduced in the late 70's in japan, the current CP vaccine was not adopted in the us until the 90's. There are good data that one dose removes the risk of death with cp, but likely only 85% get protective immunity from 1 dose, with that improving to >95% after 2 doses given at least a month apart. Time will tell if future boosters are needed but with 30+ years of worldwide data it looks good. ...Read more

They just help carry the pneumococcal proteins into the appropriate cells to create the immune response for the pneumococcal bacteria. ...Read more

Varicella vaccination - is it recommended for adults?

Varicella vaccine: Yes. There is a sure way of determining one's immunity level - a varicella titer done by a blood test. Adults need 2 doses, given one month apart. I often recommend non-immune parents to get the vaccine simultaneously when their one-year-old gets it or better still, at least a month or two before their child turns one. In addition, other non-immune family members should also be vaccinated. ...Read more

Your doctor can check titers to see if you are one of these people. ...Read more
