May 9, 2013 — The two makers of HPV vaccines have agreed to lower the prices for their vaccines to less than $5 a shot for low-income countries. The cheaper vaccine may make it easier to vaccinate girls in places where the risk of death from cervical cancer is greatest.
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.
Feb 4, 2013 — A study in South Africa finds that an experimental vaccine against TB didn't help protect infants very much against either infection with TB or development of disease. The results were a setback, but researchers say the field remains promising.
Jan 18, 2013 — The Food and Drug Administration just approved a flu vaccine made by cells taken from the fall armyworm, an agricultural pest.

Jan 17, 2013 — Flu viruses hijack the machinery inside animal cells to replicate. The theft is a complicated process that takes time. If the virus leaves the cells too early or too late, the risk of infection falls.
Jan 16, 2013 — Parents will be reassured to hear there's no evidence linking the current timeline for vaccinations to health problems.

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.
