Back in July of 2010, “Good Morning America” aired this segment, speculating about the possibility of a comprehensive vaccine that would prevent infection by every strain of flu. If a virus can be said to have an ass, this hypothetical shot would stop messing around kicking each one individually, and instead kick every flu’s ass all at once.

Now, researchers at Oxford University have successfully tested just such a vaccine. According to The Guardian newspaper, “[t]he treatment – using a new technique and tested for the first time on humans infected with flu – targets a different part of the flu virus to traditional vaccines, meaning it does not need expensive reformulation every year to match the most prevalent virus that is circulating the world.”

The shot won’t be in use for a few more years. Like all vaccines, it has to undergo lots of rigorous safety testing before it’s approved for sale. But this effectiveness test is an important step toward a day when one shot might protect you from more than just whatever bug the epidemiologists predict will be going around this season.
