needle vaccineAre you giving your child the chicken pox vaccine? That's the one vaccine that parents are most likely to refuse for their kids. But a new study shows that avoiding it has consequences.

The chicken pox is a relatively mild disease and parents who don't vaccinate figure that their kid will benefit from "herd immunity" if all the other kids in the class get the vaccine. But new research shows that children who don't get the vaccine are nine times as likely to get the disease as other children. The study authors say this is relevant "evidence to counter the misperception among some parents that unvaccinated children are not at risk for vaccine-preventable disease."

A new report from the Centers for Disease Control and Prevention shows that more poor kids are being vaccinated. Researchers looked at immunization data and found that in the year 2000, children living below the poverty line were far less likely to have received all of the recommended vaccines, as were those whose mothers hadn't finished high school, those with unmarried moms, and those with mothers younger than 30. Fast forward eight years and things have changed. The number of children receiving vaccines from public providers increased to 72 percent from 47 percent.

A new study shows no link between autism and MMR. The study was done comparing 96 children ages 2 to 15, who had been diagnosed with autism to children who did not have autism and were treated by the same doctor. Of the 96 children with autism, 8 had received no vaccine against measles, while about 41 percent had received the MMR shot and half had received the measles-only vaccine. Among the healthy children, 55 percent had gotten the MMR shot, while 45 percent had received the measles vaccine; only one child remained unvaccinated. The researchers aren't sure why the vaccinated children actually had a lower risk of autism.

The American Academy of Pediatrics, the Centers for Disease Control and Prevention, and the American Academy of Family Physicians just came out with its new 2010 vaccination guidelines.
