Mar 29, 2013 — A government study of the medical records of 1,000 kids found no correlation between the number of vaccines a child received and his or her risk of autism spectrum disorder. Experts hope the finding will allay some parents who worry that many vaccines on one day or in the first two years of life may lead to autism.
Mar 4, 2013 — More than 90 clinical trials have tested therapeutic vaccines in cancer patients, but the results have been a mixed bag. A recent study in mice suggests that changing a traditional ingredient in the vaccines could make a big difference.

Dec 17, 2012 — The preservative thimerosal keeps vaccines from going bad in places where there is no refrigeration. Anti-vaccine activists say it should be banned because it contains mercury, but public health officials insist it's safe.
Dec 12, 2012 — A roundup of the medical evidence by a group of independent researchers suggest that giving babies sugar water before injections can help comfort them. But the latest analysis is less enthusiastic about the approach than a previous review.
