What are influenza vaccines?

Question: 

What are influenza vaccines? 

Answer: 

Influenza vaccines protect against viruses that cause influenza, often called the flu. The vaccine does not protect against other viruses or bacteria that cause colds or stomach flu. Influenza is an infection of the upper airway caused by an influenza A or B virus. It can cause serious illness and sometimes death. Getting vaccinated is the best way to protect against influenza.
