These results indicate that vaccination with the flu season vaccine reduced the risk of flu-associated medical visits from flu A H3N2 viruses by one half and from flu B viruses by two-thirds for most of the population.

Overall, VE estimates suggest that the flu vaccine has moderate effectiveness for most people against the flu viruses spreading in the United States, similar to previously published reports. More information about vaccine effectiveness is available at Vaccine Effectiveness — How well does the flu vaccine work? However, VE against flu B was similar to what was seen in other age groups, while VE against flu A H3N2 viruses in people 65 and older was significantly lower than in other age groups.

CDC recognizes the need for developing better flu vaccines in the elderly. Scientists continued to work on better ways to design, conduct and evaluate non-randomized i. CDC has been working with researchers at universities and hospitals since the influenza season to estimate how well influenza vaccine works through observational studies using laboratory-confirmed influenza as the outcome.

These studies currently use laboratory-confirmed medically-attended influenza virus infections as a specific outcome. Similar studies are being done in Australia, Canada and Europe. In May and September , flu vaccine manufacturers originally projected about million doses would be available for the U. Recent updates from manufacturers to CDC indicate that more doses of flu vaccine were actually produced, totaling million doses.

Antiviral resistance means that a virus has changed in such a way that antiviral drugs have become less effective in treating or preventing illnesses caused by the virus. Samples of viruses collected from around the United States and the world are studied to determine if they are developing resistance to any of the antiviral medications currently recommended to treat influenza.

CDC routinely collects viruses through a domestic and global surveillance system to monitor for changes in influenza viruses. CDC also works with the state public health departments and World Health Organization to collect additional information on antiviral resistance in the United States and worldwide.

The information assists CDC in making informed recommendations for treatment and prevention of influenza in the United States. To receive weekly email updates about Seasonal Flu, enter your email address:.
