Flu, caused by influenza viruses, is a serious disease that can lead to lengthy periods of illness, hospitalization, and even death. Complications of flu can include bacterial pneumonia, ear infections, sinus infections, and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes. Last year it is estimated there were 70,000 flu-related deaths. Your best defense against influenza is to get an annual flu vaccine approved by the FDA. Because last year’s strain will be different from this year’s strain, it is important to schedule your vaccination each year.
Five facts about flu vaccines.
- The flu shot stays effective for up to eight months. It takes about two weeks after vaccination for your body to develop antibodies that give you protection.
- Flu viruses typically spread in fall and winter, with peak activity between December and February. Getting your vaccination in October or November ensures coverage through the hard-hit months.
- Almost everyone six months of age or older benefits from the flu vaccine.
- Flu shots are divided into two camps: trivalent flu shots target three flu strains. Quadrivalent flu shots target four strains of the flu. Most flu vaccines in the US are quadrivalent.
- Vaccines are available in egg-free variations and in nasal form through Flu Mist, a mist sprayed up your nose. The nasal spray is widely used in children and not recommended for people over 65 years of age.
Flu vaccinations have been shown to reduce the severity of illness in people who get vaccinated but still get sick. Getting yourself vaccinated may also protect people around you, including those most vulnerable to serious flu illness, like babies, older people, and people with life-altering illnesses.
Schedule your flu vaccine today and check with your healthcare provider to determine which flu vaccine is best for you based on your age, health status, and other factors.
