A report by Centers for Disease Control and Prevention showed that this year's flu vaccine was not effective enough, because vaccine predictions failed.

Every year scientists track influenza strains and their mutation, analyze gathered data to predict which strains will be more dangerous and widespread in the coming season. Usually, scientists are giving successful results and those who are being vaccinated as directed are being from 70% to 90% protected from the disease. It is difficult to guess which strains will be more active in the coming season, because the molecular structure changes every year.
