October 8, 2013 Bombs targeting polio vaccinators have threatened the global effort to stamp out the disease once and for all. The attacks are likely to continue, researchers warned, unless there's a change in eradication strategy toward local action.
September 30, 2013 The whooping cough vaccine isn't perfect, but public health officials suspected that something else contributed to the 2010 pertussis outbreak in California. A study finds that neighborhoods where more parents filed for vaccination exemptions for their children had higher rates of infection.
September 12, 2013 Eight outbreaks of measles have infected at least 159 people so far this year, the CDC reports. All of the outbreaks were caused by people traveling internationally and bringing the virus back to the U.S. Communities that don't vaccinate children for religious reasons were hardest hit.
August 27, 2013 Since the rollout the rotavirus vaccine for infants in 2006, the spillover benefits to children and adults who weren't immunized have been enormous. Hospitalizations due to the stomach virus have dramatically declined in those populations, too.
July 23, 2013 Physicians are partly to blame for the increasing popularity of untested treatments, says Dr. Paul Offit. Rather than pushing back against misguided patient demand, he says, doctors have "acted like waiters at a restaurant, simply asking, 'What would you like?' "
May 22, 2013 A measles epidemic in Wales that has infected more than 1,000 people is the fallout from a fraudulent paper linking the vaccine and autism published almost 15 years ago, health officials say. Many of the children and teenagers sick with measles were never vaccinated.
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.
March 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.
March 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.
February 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.
January 18, 2013 The Food and Drug Administration just approved a flu vaccine made by cells taken from the fall armyworm, an agricultural pest. The cells produce copies of a piece of the flu virus's outer coat that primes the immune system. Conventional vaccines use the whole virus and take longer to produce.
January 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.
January 16, 2013 Parents will be reassured to hear there's no evidence linking the current timeline for vaccinations to health problems. A review of all available scientific data looked at a wide range of medical conditions — including diabetes, autism and epilepsy — before declaring that there's no reason to worry.
