High level of efficacy and safety of antiviral vaccines and unsubstantiated critique

: To counterbalance the unsubstantial declarations of some vaccinologists that vaccines and vaccination are not only useless, but also injurious to the health, this work represents the evidence that vaccines and vaccination not only reduce the morbidity of viral infection, but also allow some viral diseases to be eradicated and eliminated. The work also adduces the data about reducing economic impact of viral infections with the help of vaccination, as well as the data, which clearly show that serious reactions to vaccination are thousands of times less frequent than reactions and complications caused by infectious diseases.
