How do COVID-19 vaccines work?

Vaccines help people develop immunity to an epidemic or other germ. A vaccine introduces a less harmful a part of that germ — or something created to seem or behave love it — into a person’s body. The body’s system develops antibodies that fight that specific germ and keep the person from getting sick from it. Later, if the person encounters that germ again, their system can “recognize” it
and “remember” the way to fight it off.

How will a vaccine prevent COVID-19?


The coronavirus that causes COVID-19 has spikes of protein on each viral particle. These spikes help the viruses attach to cells and cause disease. a number of the coronavirus vaccines in development are designed to assist the body “recognize” these spike proteins and fight the coronavirus that has them.
An effective vaccine will protect someone who receives it by lowering the prospect of getting COVID-19 if the person encounters the coronavirus. More important is whether or not the vaccine prevents serious illness, hospitalization and death. At this point , all three vaccines are highly efficacious at preventing serious illness, hospitalization and death from COVID-19. Widespread
vaccination means the coronavirus won’t infect as many of us . this may limit spread through communities and can restrict the virus’s opportunity to still mutate into new variants.
