Combined with an earlier malaria vaccine and insect-control tools such as pesticides, experts are hopeful we can regain the ground we've lost to malaria over the last eight years.

* Old polio vaccines can mutate into a dangerous version of the disease — but a new ‘super-engineered’ vaccine is much safer

Existing polio vaccines have nearly eradicated the disease; today the virus is endemic in just two countries, Afghanistan and Pakistan. However, one of the lingering problems is that the oral polio vaccine can, on rare occasions, mutate and allow vaccinated individuals to spread polio to their unvaccinated neighbors. Scientists may have devised a permanent solution to this alarming side effect by engineering a polio vaccine that cannot mutate. The enhanced immunization is undergoing clinical trials to en...
