Chickenpox Vaccine Proving Very Effective Over Time

Friday, April 5th, 2013

The varicella vaccine, which immunizes against the virus that causes chickenpox, has been found in a new study published online in the journal Pediatrics to be highly effective after one dose, and even moreso after two doses.  More from The New York Times:

Before 1995, when the varicella vaccine came into widespread use, chickenpox affected about 90 percent of the population, leading to thousands of hospitalizations and about 100 deaths a year.

“Now a very safe vaccine will totally prevent it from happening,” said the lead author, Dr. Roger Baxter, co-director of the Kaiser Permanente Vaccine Study Center in Oakland, Calif.

Between June and November 1995, researchers began studying 7,585 children vaccinated between the ages of 1 and 2. They interviewed their parents every six months, asking about the occurrence of both chickenpox and shingles, the painful rash that can occur after recovery from chickenpox. In June 2006, a second vaccine dose was recommended, and the researchers followed those cases through the end of the study in 2009.

The analysis, published online in Pediatrics, found 1,505 cases of chickenpox, all except 30 of which were mild or moderate, involving less than 300 lesions. There were no cases among children who received a second dose.

Chickenpox-Laced Lollipops Cause Stir in Tenessee

Thursday, November 10th, 2011

A Nashville, Tennessee woman has caused a stir by offering for sale spit, cotton swabs, and lollipops that were licked by her chickenpox-infected children.  The offer, which she posted on Facebook, was meant to help parents who wanted to expose their children to the varicella virus instead of giving them the vaccine against the chickenpox.

According to a report from NPR:

State health officials were horrified at the prospect, and pointed out that not only is the varicella vaccine much safer for children than getting the disease itself, but spreading the virus could pose a serious risk to children who can’t be vaccinated because they are undergoing cancer treatment or have other health problems.

Deaths caused by chickenpox have plummeted since the vaccine was introduced in 1995, according to a study published in July.

Before the vaccine was introduced, parents would sometimes expose their children to others who were sick with the disease, so the children would have a reduced risk of serious infection as adults. The idea has since been adopted by some parents leery of vaccines.

NPR reported that once the story caught the attention of health officials, the Facebook page now offers “pox parties” for local families only–no shipping of items allowed.
