HEYA!!!
HERE IS YOUR ANSWER,
> Vaccines teach the immune system by mimicking a natural infection.
> For example, the yellow fever vaccine contains a weakened form of the virus that doesn’t cause disease or reproduce very well.
> Human macrophages can’t tell that the vaccine viruses are weakened, so they engulf the viruses as if they were dangerous.
HOPE IT HELPS YOU,
THANK YOU.☺️☺️
