You need a new shot every year because current flu vaccines provide limited and temporary protection. But researchers’ new strategy could mean a one-and-done influenza vaccine is on the way.
The smallpox virus appears to have been with humanity for millennia before a global vaccination drive wiped it out. Current genome research suggests how smallpox spread and where it came from.
Responsables de gastro-entérites, les norovirus sont hautement infectieux. Mais nous ne sommes pas tous égaux face à la maladie : notre vulnérabilité est notamment liée à notre groupe sanguin.
Norovirus, the winter vomiting bug, is highly infectious among people in confined places – like cruise ships. But not everyone is equally vulnerable. Your blood type may determine if you get sick.

You may think that your milk-drinking, ice cream-licking days are behind you as you battle the discomfort of lactose intolerance. But there maybe be a way to reverse the situation.
Part of the problem was a mismatch between the influenza strains circulating and the vaccine available. Here’s how annual flu shots are formulated.
