The flu evolves quickly. In one year, 99 percent of the flu strains have become resistant to Tamiflu, an antiviral drug.
Suck to be the company that invented that medicine.
Impressive that something that's not even really alive can evolve and adapt that quickly. I guess one year is 100 generations for a virus, but still. There's a reason you have to get a new flu vaccine every year - your immunization is for the old strains that no longer exist.
Really, it's a wonder that we managed to conquer measles, polio, smallpox and others! Why haven't they mutated to escape those vaccines? Particularly given how ridiculously contagious measles is.
