COVID-19 VACCINE PREVENTION
In this literature review, the features of the causative agent of a new coronavirus infection are considered. The existing COVID-19 vaccines, the stages of their development, the test results, and the expected and identified side effects of their use were studied. The pros and cons of COVID-19 vaccine prevention are presented, taking into account the analysis of economic and social effectiveness. The necessity of vaccination of the population against coronavirus infection is justified. Definitely, vaccination is necessary, since the main value is the health and life of a person, so it is necessary to take measures to preserve it. To combat the global pandemic, the most effective method of prevention is the use of vaccines, because the economic costs of mass coronavirus infections are much greater than the costs of a mass vaccination campaign of the population. The coronavirus is highly contagious, transmitted by airborne droplets, and one person can put a large number of people at risk of infection.
