PNI: understand how one of the largest vaccination programs in the world works – A Gazeta News

One of the largest vaccination programs in the world that, in the last 49 years, has led Brazil to eliminate and control several vaccine-preventable diseases: the PNI is a heritage of all Brazilians and an international reference. The abbreviation is for the National Immunization Program, responsible for preparing Brazil’s vaccination policy, from the purchase of routine vaccines to the definition of the public that will be immunized.

The Brazilian immunization program offers, free of charge through the Unified Health System (SUS), more than 20 immunizations for various diseases, with 17 vaccines for children, seven for adolescents, five for adults and the elderly and three for pregnant women. All are part of the National Vaccination Calendar, a document that establishes the application of routine vaccines for each stage of life.

History and role of PNI

Created in 1973, the National Immunization Program – the PNI – is responsible for the National Immunization Policy that aims to reduce the transmission of vaccine-preventable diseases, the occurrence of severe cases and deaths, with the strengthening of integrated health surveillance actions for the promotion, protection and prevention in health of the Brazilian population.

The PNI is responsible for defining the country’s vaccination policy, from the acquisition of immunobiologicals to their availability in vaccination rooms, establishment of norms and guidelines on indications and recommendations for vaccination throughout Brazil.

With almost 50 years of existence and 47 different immunobiologicals offered, the PNI is one of the largest vaccination programs in the world, recognized by the Pan American Health Organization (PAHO), an arm of the World Health Organization (WHO), as a world reference.
The PNI is also responsible for defining the National Vaccination Calendar, which includes all routine vaccines. This important guideline accompanies all Brazilians from the first day of life, guiding the period and the vaccines that should be taken.

Understand the National Vaccination Operational Plan against Covid-19 (PNO)

Also under the coordination of the Health Surveillance Secretariat (SVS), is the PNO – National Plan for the Operationalization of Vaccination against Covid-19. The acronyms are similar, but the functions are different.

After the approval of the first Covid-19 vaccine by the National Health Surveillance Agency (Anvisa) for application in Brazilians, the Ministry of Health had already structured a document that would guide the vaccination campaign, with important guidelines and guidelines for states and municipalities. , ensuring that the campaign took place equally throughout the country – the PNO. This was necessary in view of the emergency caused by the virus and the short time to structure a vaccination campaign.

The PNO was built by the Ministry of Health, together with the National Council of Health Secretaries (Conass) and the National Council of Municipal Health Secretaries (Conasems) in close partnership with Scientific Societies, Class Councils and the Pan American Health Organization. (PAHO/WHO).

The PNO defines and details the operationalization of vaccination against Covid-19 in the national territory, supporting states and municipalities, as well as health professionals in the planning and operationalization of vaccination. Since the beginning of the campaign, around 520 million vaccines have been distributed to the states and the Federal District.

Covid-19 vaccine

For any vaccine to be incorporated into the National Vaccination Calendar of the PNI, a technical evaluation is necessary, considering several aspects, such as the epidemiological situation, the behavior of the disease over time and the type of vaccine. This process also goes through the analysis of the National Commission for the Incorporation of Technologies in the Unified Health System (Conitec).

It is important to clarify that the Covid-19 vaccines used in Brazil – Astrazeneca, Janssen, Pfizer and Coronavac – continue to follow the PNO guidelines and the national vaccination campaign is advancing based on the recommendations of the Ministry of Health published in the updates of the document that is being published. in the 13th edition. Therefore, immunizers against Covid-19 need to go through a series of steps before defining their inclusion in the calendar, respecting the technical process of incorporation defined by the Ministry of Health.
