Influenza, caused by a virus, primarily affects the respiratory system. Influenza is also known as the flu, seasonal flu or respiratory flu.
While the flu vaccine will not protect against all cases of influenza, it does provide significant protection. Each year, the flu vaccine is designed to provide immunization against the three main strains of flu researchers predict will be prevalent that year. Even if an individual contracts a different form of the flu, the flu vaccine is likely to provide some protection.
Although gastrointestinal illness with vomiting and diarrhea is often referred to as “stomach flu,” this type of illness is not true influenza or “flu.” The flu vaccine does not provide protection against this type of gastrointestinal illness.
During the 2014-2015 influenza season, the vaccine available in the U.S. will again provide immunization for the following strains of influenza viruses:
- an A/California/7/2009 (H1N1)pdm09-like virus
- an A/Texas/50/2012 (H3N2)-like virus
- a B/Massachusetts/2/2012-like virus.
Some of the 2014-2015 flu vaccines, know as quadrivalent vaccine, will also protect against an additional B virus called B/Brisbane/60/2008-like virus.
Vaccination for influena is available in injectable and intranasal forms. The intranasal form is not generally recommended for individuals with neuromuscular disease, however.
In 2010, the Centers for Disease Control and Prevention (CDC) changed their recommendations regarding who should receive the flu vaccine. The CDC now recommends that everyone over the age of six months receive the flu vaccine.
Individuals with neuromuscular disease are considered to be at risk for serious complications from influenza. According to the MDA, however, individuals with certain types of neuromuscular disease should not receive the flu vaccination: It is important to check with your physician before receiving the flu vaccination. In addition, those taking immune-suppressing drugs (i.e., corticosteroids) may not be able to be vaccinated for the flu and should check with their physician before being vaccinated.
The CDC considers the flu vaccine to be one of the most important preventative measures against the flu. The CDC also recommends preventative measures such as frequent hand washing, covering a cough, limiting contact with others if you are ill sick and with others who are sick, and avoiding touching your eyes, nose, and mouth.
According to the CDC, if you do contract influenza, a visit early to your physician may result in an antiviral medication being prescribed by your physician. These antiviral medications can help shorten the duration of illness and decrease severity.
