About 4 years: Then a booster shot at age 4 will give lifelong protection. The shot only takes away about 80% of the chance of getting the disease, however, but it takes away all chance of dying from the disease - disease after the shot is quite mild. ...Read more

Chickenpox: Vaccine as with any other vaccines can cause redness and slight swelling at the site of shot. The first vaccine will give you 95% protection and close to 100% the second time around. Some people will come down with mild chickenpox after the shot. If not sure, please consult with your physician. ...Read more

How long has the chicken pox vaccine actually been tested?

More than 30 years: The CP vaccine we use today was developed in japan in the late 70's & reviewed by our fda for ~ 16 years before they decided the cost of general use offset the cost of deaths/hospital care & work loss in the us. It had been available for limited use thru the cdc for cancer patients during its review.It was approved in 1995 & adoped by may states thereafter. ...Read more

Lifetime: It should be life long. It produces immunity about 75% of the time after 1 shot and close to 100% after 2 shots. There are no recommendations for boosters unless blood testing shows that you are not immune, after receiving the 2 shots. ...Read more

Until no new sores.: Chicken pox, which you can still get mildly even if you've been vaccinated, is contagious until all the sores are crusted over and there are no new ones. If you see any new sores at all, it's still contagious and other people are at risk. ...Read more

4-6 weeks: Hard to be precise because the answer is based on when it was measured and no one checked day after day. At 4-6 weeks, immune response was strong. The exact % response varies by age. A second later dose raises overall response rates a small but significant degree. Two doses seem to keep kids protected for many many years; adults not as exact. http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5604a1.htm. ...Read more
