The theme of our research is the importance of vaccination which, due to the large number of people who do not get vaccinated and do not recognize the importance of this act, has generated worldwide outbreaks of diseases that had already been eradicated. Our goal is to minimize the number of people who do not get vaccinated in Brazil, through the development of an application that will make the population aware of the importance of vaccination, in addition to making people aware of the importance of vaccination and creating a platform that facilitates access to information, always stimulating society's interest in public health, also including a news feed and a virtual booklet, which will bring an immunization control in the country. The application will be easy to use for all ages, will provide content for both the elderly and teenagers, informing, for example, the importance of the vaccine against HPV, bringing risks, consequences, treatment, transmission, prevention, among others. The methodology used was bibliographical, through the reading of articles, websites and periodicals. In addition, questionnaires were applied that led to the confirmation of some of our hypotheses, such as that people stop being vaccinated due to fake news, lack of information, lack of interest and fear. The beginning of several news related to vaccination and measles epidemic cases, which occurred recently in our country, corroborate the development of this research, since the intention is to inform about the purpose and importance of vaccination. Our experience in the Startup Teens project, which aims to encourage young people to create and develop entrepreneurial ideas, positively contributed to a better organization of our group and work.
