How does the vaccine trigger an immune response?

In response to the introduction of inactivated (killed) and purified particles of the virus of coronavirus infections in the body, the immune system is stimulated and specific antibodies are produced.
And when the pathogenic virus of coronavirus infections enters the body, the antibodies developed in advance after vaccination attach to the viral proteins and block them. In this state, the virus can not harm the body.
Vaccination of a large number of people contributes to the creation of collective immunity. The more people who are vaccinated, the less likely they are to encounter the disease.
To stabilize and prevent the further spread of coronavirus infections, vaccination among the population should be maintained at a level of at least 60%.
