: Yes, there are four main types of flu shots available:

1; The traditional flu shot that is injected into the muscle. It contains flu-particles but will not give you the flu.

2; The high-dose shot that is the same as the shot above but contains a higher dose

3; The intradermal flu shot that contains the same vaccine as the others but can be injected just skin deep and can be used on people age 18 to 64.

4; The nasal spray vaccine that can be used on people age 2 to 49. It contains a live, weakened flu virus.
