Fighting the flu this year just became tougher. One of the most common go-to medicines for thousands suffering from the flu is not as effective this year.
Tamiflu is designed as a quick-fix for the flu and last year did it's job in nearly every case. But this year, it's not nearly as effective... Ninety-nine percent of people infected with the flu tested positive for a Tamiflu resistant strain. If doctor's suspect that strain, the next best option is a medicine called Relenza, but it is more expensive and harder to take. It's a powder that must be inhaled and can even cause lung spasms, and it's not safe for people of all ages.
