vaccines against influenza

Influenza vaccines protect people by stimulating the immune system to recognize and fight the flu virus. Each year, scientists predict which flu strains will be most common and include them in the vaccine. When vaccinated, your body creates antibodies that provide immunity, reducing the risk of illness or lessening severity if you do get sick. The flu vaccine is typically given as a shot and is recommended annually because flu viruses change regularly. Getting vaccinated not only helps protect yourself but also reduces the spread of the virus to others, especially those who are more vulnerable.
