What is a flu vaccine?
“Influenza (flu) vaccines (often called “flu shots”) are vaccines that protect against the four influenza viruses that research indicates will be most common during the upcoming season. Most flu vaccines are “flu shots” given with a needle, usually in the arm, but there also is a nasal spray flu vaccine.” – CDC
How effective is the seasonal flu shot?
“Influenza (flu) vaccine effectiveness (VE) can vary. The protection provided by a flu vaccine varies from season to season. It depends in part on the age and health status of the person getting the vaccine. It also depends on the similarity or “match” between the viruses in the vaccine and those in circulation. During years when the flu vaccine match is good, it is possible to measure substantial benefits from flu vaccination in terms of preventing flu illness and complications. However, the benefits of flu vaccination will still vary, depending on characteristics of the vaccinated persno (for example, their health and age), what flu viruses are circulating that season and, potentially, which type of flu vaccine was used. More information is available at Vaccine Effectiveness – How well does the Flu Vaccine Work.” – CDC
