By Nathan Seppa, Science News Two are better than one when it comes to chicken pox vaccinations, scientists report January 5 in The Journal of Infectious Diseases. The chicken pox shot, first made available in the United States in 1995, has already proved able to prevent the disease in about 80 to 85 percent of children who get a single dose. In 2006, the Centers for Disease Control and Prevention and the American Academy of Pediatrics jointly recommended a two-shot approach, suggesting that children get the doses four to six years apart.
The new study supports this revision: Adding another shot ups disease prevention to nearly 100 percent. Pediatrician Eugene Shapiro of Yale University School of Medicine and his colleagues identified 71 children who had contracted chicken pox between 2006 and 2010, verifying the diagnoses with tests showing viral DNA in skin lesions on the kids.

Before the chickenpox vaccine began to be routinely given in 1995, chickenpox was a very common childhood illness, that even when it wasn't serious, still left children miserable for at least a week.
And unfortunately, sometimes these chickenpox infections did become serious, leading to hospitalization and even death. In the United States, before routine use of the chickenpox vaccine, 'there were an average of 4 million cases of varicella that resulted in 10,500-15,000 hospitalizations and 100-150 deaths every year,'1 many of which occurred in children. Now that Varivax is routinely used, there has been 'a substantial decrease in incidence'2 of chickenpox and its complications. Although 'varicella vaccination has been found to be highly effective in preventing disease,'3 it is not perfect. The ACIP is now recommending that children get a second dose of the chickenpox vaccine when they are four to six years old. Chickenpox (Varicella) Vaccine: Schedule and Side Effects.

Viruses that have been attenuated are less virulent than viruses that are not. Why Do People Need a Chickenpox Vaccine?
