University of Texas Southwesterns scientists have created a new flu vaccine that can protect us against any kind of flu, not just one type. Unlike the current type of vaccines, this can even protect us if the virus mutates.Thats the big problem of the current vaccines: every year, medical experts guess whats going to be the dominant flu strain and create a vaccine using a weakened version of that virus. If that virus mutates, the vaccines becomes useless, which is why people get the flu even when they get vaccinated.
