September 13, 2012 Young kids who get all their whooping cough shots on time could become susceptible to the disease again when they're between 8 and 11. Researchers say the immune protection conferred by the current vaccine loses its punch.
September 11, 2012 The federal health law makes it easier for most people with private insurance to get recommended vaccines without a copay. But the changes don't apply to people covered by Medicare.
September 10, 2012 In a study with about 4,000 Thai schoolchildren, a vaccine for dengue fever works well against some strains of the dengue virus. But the overall level of protection was lower than hoped for. The results suggest that a vaccine for dengue fever can be developed eventually.
September 4, 2012 The results comes from Zanzibar, an island state of Kenya, where half the people in six rural and urban areas received two doses of oral cholera vaccine. The vaccinations led to fewer bacteria circulating, lowering the infection risks even for those who weren't vaccinated.
August 17, 2012 After a successful project to vaccinate Haitians against cholera, the World Health Organization is calling for the establishment of a global stockpile of the vaccine to respond to outbreaks like the one that struck Haiti.
August 3, 2012 A study from Australia finds that the current vaccine for whooping cough wanes more quickly than expected, which may be helping to fuel the epidemic that's been plaguing the West Coast of the U.S.
August 1, 2012 Challenging the view that rabies is always fatal, scientists have discoverd a group of Peruvians who show signs of surviving rabies from vampire bats, despite never being vaccinated for the virus. The findings suggest that some people may become resistant to rabies after they're exposed to it over time.
July 17, 2012 Almost 90 percent of the target population – half in Port-au-Prince and the other half in a remote rural area – got fully protected against cholera. The results defy the forecasts of skeptics who said in advance of the campaign that it would be lucky to protect 60 percent of the target populations.
July 9, 2012 A protein in silk could help stabilize vaccines and medicines. Researchers at Tufts University have found a little bit of the protein can help preserve heat-sensitive medicines that usually require refrigeration.
June 11, 2012 Some 338 people have been infected with whooping cough in Oregon this year. But that's just a small fraction of the number of cases the state of Washington is reporting. Health experts say the booster shot is not 100 percent effective at preventing the disease, but people who have it are far less likely to get sick.
May 25, 2012 Jet injectors have been delivering drugs and vaccines without needles since the Star Trek era, but never caught on widely in real-world medicine. A device developed at MIT promises to change that, with computer-controlled precision and an injection as inconspicuous as a mosquito's jab.
May 10, 2012 KUOWAbout 1 in 5 infants who get whooping cough will get pneumonia, and in some cases die. In Washington state, where confirmed cases are 10 times as high as they were last year, officials hope federal investigators will help them trace the source of the current outbreak.

April 17, 2012 Health and Human Services Secretary Kathleen Sebelius is expected to show her support for two big vaccination initiatives in Haiti, including one against cholera. Previously, U.S. health officials were cool to the cholera pilot project .
April 13, 2012 Cholera was introduced into Haiti 18 months ago. So far, more than a half-million people have gotten sick and 7,000 have died. Public health authorities say the disease will linger for a long time because Haiti has the worst sanitation in the Western Hemisphere.
