I got the chicken pox vaccine but still got chicken pox, why?
Before 1995, chicken pox was a routine part of growing up. But in that year, scientists introduced a vaccine in the United States. A vaccine is a mixture, usually a liquid, which contains small amounts of a virus or bacterium. Vaccines help prevent dangerous and infectious diseases. The single-shot chicken pox vaccine has shown to prevent the disease in 80 to 85 percent of the children who receive it, according to Science News. Unfortunately, you must have been in the 15-20% of the people where the vaccine did not do it's job.
In 2006, people were advised to start getting two doses of the vaccine to keep chicken pox at bay. This recommendation was made by the Centers for Disease Control and Prevention and the American Academy of Pediatrics.
