Scientists Learn How Your Cells Help Influenza Evolve Faster

As we head into flu season, new batches of vaccines are being produced that will hopefully protect against this year’s most common strains of the virus. Even if you got vaccinated last year, influenza mutates so quickly you need this year’s vaccine to be well-protected. Researchers have long studied the …
