Immunization is one of the most effective ways to protect yourself and your community from various diseases
National Vaccination Day, celebrated on October 17, reinforces the importance of vaccines for individual and collective health, highlighting their essential role in the prevention, control and even eradication of various diseases. The date serves as a reminder that immunization is one of the most effective ways to protect oneself and the community, preventing epidemics and reducing the circulation of viruses and bacteria.
Keeping your vaccination program up to date is an attitude of responsibility towards your own health and the well-being of everyone. However, data from the 2025 VacinaBR Yearbook, prepared by the Instituto Questão de Ciência (IQC), shows that vaccines requiring multiple doses, such as the triple viral vaccine, have high escape rates between the first and second applications, exceeding 50% in some states.
