Vaccination is the introduction of a preparation into the human body that promotes the development of immunity to a disease. The vaccine undergoes multiple laboratory tests and is completely safe for humans.
Vaccination is the most effective method of preventing various infectious diseases. The method is recognized and widely used worldwide.
Vaccination for adults is not universal. The only exception to this rule is vaccination against tetanus and diphtheria, which is administered to the entire adult population.
In all other cases, vaccinations are given to those adults who are in certain risk groups for infection with a particular infectious disease.
Risk groups can be determined based on age criteria. For example, vaccinations against influenza and pneumococcal infection are indicated for all people over 65 years of age.
