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

How long does the chicken pox vaccine last for children? Will a booster be needed in the future?

May need a booster: One dose of chickenpox vaccination will provide long term but probably not life long immunity. Immunity can be checked by a blood test. A booster maybe needed in the future. The effectiveness of the vaccination depends on the individual. Some people (1 in 5)will still get chickenpox despite the vaccination but they tend to get a much milder form of the disease. ...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.

How long is it supposed to it take after getting varicella vaccine to become immune to chicken pox?

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.

Does a chicken pox vaccine hurt more than a novocain (procaine) shot?

Not as bad.: 1 of the effects of lydicane is to numb the area but unfortunately there's a burning sensation as that process takes place within the nerve cells.

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

Shot reaction: A percentage of the vaccine recipients may breakout with atypical chickenpox, which is not the same as wild disease. Since the virus involved has been weakened in the lab, these kids have fewer spots and none of the dreaded complications of the wild disease. They could pass the weakened virus to others, but it would only be a free exposure varicella vaccine & unlikely to cause a clinical outbreak. ...Read more

Do they use the cell line of an aborted fetux to make chicken pox vaccine?

No: This is an old rumour, but not entirely correct. It is true that some of the early vaccines (mainly rubella) were developed using human tissue derived from a fetus not purposefully aborted for this reason at all. This occurred 30-35 years ago. The important point is that the vaccines have saved millions of lives, prevented serious infections and disability, and kept our children healthy. ...Read more
