The immunopreventable diseases answer for half of all the deaths in countries with smaller development index: 90% of these deaths attributed to diarrheic diseases, breathing diseases, AIDS, tuberculosis, malaria and measles13-16, and many of them could be preventable through the vaccines. Based on the data collected in this research, still today citizens get sick and are hospitalized by immunopreventable diseases. As we observed in in this study, there were 457,479 hospitalizations in the period from 2008 to 2018, in Brazil with a budget impact of R$389,243,264.85. According to the Ministry of Health data (https://saude.gov.br/noticias/agencia-saude/45877-secretary-national-of-surveillance-in-greet-speech-on-supply-and-budget-for-vaccine-haul-of-investment-for-to-area), the budget destined to PNI corresponds to 53% of the general budget of the Health Surveillance Secretariat. This budget destined for purchase vaccines and inputs related to immunization totalized R$ 45.3 billion, according to the Annual Budget Bill (PLOA) of 2020. Considering the total budget of SUS (R$147,43 billion for the health care in 2019, according to data of the Brazilian Office of Comptroller General(CGU) (http://www.portaltransparencia.gov.br/funcoes/10-saude?ano=2019), the expenses with immunopreventable disease hospitalizations are inside the total of R$114.18 billion of expenses executed for the area of the health (for hospital and outpatient care). In this context, analysing the direct costs with hospitalizations related to the immunopreventable diseases in SUS, it was observed the reflex of the actions of the public politics of health indirectly, mainly in the country, independent of the regional differences that knowingly exist. If was observed the total expenses here lifted, it is possible saving more than R$389 million avoiding diseases that can be forewarned for measures effective and thoroughly accessible for every Brazilian population = the vaccines.
Another observed interesting data is the fact that the hospitalizations for the immunopreventable disease didn't decline in uniform way in the different country’s areas, and some illness until presented growing tendencies (as mumps, for instance). This situation should be analysed with very carefully, because it raises the existence of regional differences among health care quality, services structures installed, social inequalities that impact in the population’s health, and differences in the regional public politics of facing each immunopreventable disease (despite the national politics of prevention, promotion, diagnosis and treatment of each illness) 17-24.
Nowadays, the financial resources are being destined to the hospitalizations of Immunopreventable diseases can be forewarned with effective measures as the vaccines, if the population was appropriately vaccinated, these resources could be used for other situations, so many needs of public health. This manuscript brings an opportunity for improvement that is the importance of employing awareness public and private campaigns for the importance of increase the vaccination coverage in all geographic areas (table 1), regarding the regional differences (differences in vaccination’s culture, health services access, health budget, health services territorial distribution, and many differences in the population reality that differ between the Brazilian geographic area).
All studies based on public secondary databases have the limitation, already known, of underreporting and underreporting of the analysed system itself, because these are dependent on the databases being fed by the employees responsible for the system. In the case of the SUS, these data are feeders in a decentralized manner and regionalized by States and Municipalities. However, despite the notorious underutilization of the system, these are the official data that are used for the development of public health policies in Brazil.
