Even if researchers have recently stated that the vaccine against chickenpox could diminish its occurrence in children with almost 90%, some doctors and health officials fear that many parents don’t take the disease seriously enough as to get their children vaccinated.

A study released in the journal of Pediatrics on Tuesday and made by the Centers for Disease Control and Prevention showed that vaccination against chickenpox (varicella) between 1995 and 2005 reduced the number of hospitalizations with 75% and reduced deaths by 74%. The greatest improvements were shown in young children.

The authors of the study and the article concluded that the “U.S. varicella vaccination program has dramatically reduced varicella incidence and related complications, hospitalizations and deaths."

Still, one single dose of the vaccine, which means 85%, is not enough to kill the virus in “high contact” settings, as schools or public places. The researchers advise parents to get a double-dose of the vaccine as to be sure their children don’t catch the disease.

Dr. James King, professor of pediatrics at the University of Maryland School of Medicine, stated that in his “failing memory, chickenpox was responsible for 100-200 deaths per year in the U.S.,” bearing in the mind the parents’ fear to get their kids vaccinated.

The scaly, red scabs and the itchy bumps on the skin create a great discomfort for young children. To have to stay indoors while the disease is over is really making the children suffer. But the disease doesn’t affect only the children, as also people older than 30 could get the virus inside their bodies.
