Abstract
Vaccination, or active immunization is the most effective means by which it is possible to significantly reduce the incidence of certain infectious diseases. Consistent implementation of immunization programs in the Czech Republic and many other countries around the world has shown that infections are successfully controlled by systematic vaccination.
Besides decree defined regular, special and emergency vaccination, extra vaccinations of adults and people with chronic diseases and/or immunodeficiency is becoming increasingly important. For adults there are also available vaccines to mandatory or (strongly) recommended immunization before traveling abroad.
Age, comorbid chronic diseases, lifestyle, working conditions and pregnancy play the important role in deciding. Plenty of information provided by the general practitioners are essential to improve the unsatisfactory immunization of adults against certain infectious diseases.
