What Is A Flu Vaccine?
Influenza (flu) vaccines (often called “flu shots”) are vaccines that protect against the four influenza viruses. The research indicates that these viruses are commonly spread during winter season. Most flu vaccines are “flu shots” given with a needle, usually in the arm. However, there is also a nasal spray flu vaccine.


How Does Flu Spread?
It mostly spreads through droplets in the air when people with flu cough, sneeze, or talk. It can spread from up to six feet away. Although it isn't as common, the flu can also spread from surfaces. If you touch something the virus is on and then touch your nose, mouth, or eyes, it may enter your body.
