ST. LOUIS, Mo. (KMOX) – Four works better than three. That’s the bottom line of new flu vaccine research out of St. Louis University.
Traditionally, the flu vaccine contains three weaken strains of influenza — two of influenza A and one of influenza B. But St. Louis University infectious diseases specialist Robert Belshe says they tested and found by including another B virus to the vaccine, protection is even better.
“This is an updated version of flu mist — the nasal spray flu vaccine that is very very effect in preventing flu particularly in children.” said Belshe. “Also its probably better for adults. Young adults get influenza B when their children get sick.”
Belshe hopes this will lead to fewer cases of influenza in vaccinated people.
The FDA has already approved this vaccine. It should be available by fall of 2013.
