Polio vaccination in Brazil remains below expectations, according to the Ministry of Health. The National Campaign for Vaccination against Poliomyelitis and Multivaccination of 2022, which aims to achieve vaccination coverage equal to or greater than 95% in the 1 to 5-year-old age group, has reached only 51% of this audience so far.

The campaign started on August 8th and was scheduled to continue until September 9th, but was extended until the 30th with the aim of increasing vaccination coverage and population adherence to vaccination.

The target group is 14.3 million children under five years of age, and children under 1 year of age must be immunized according to the vaccination status for the primary schedule. Children aged 1 to 4 years should take one dose of Oral Poliomyelitis Vaccine (OPV), provided they have already received the three doses of Inactivated Poliomyelitis Vaccine (VIP) in the basic regimen.

Brazil has not detected cases of poliomyelitis since 1989, but the decrease in vaccination rates may lead to a return of the disease. According to data from the Ministry of Health, a progressive drop in vaccination coverage has been detected since 2015, when the rates reached 98.3%. In 2021, vaccination coverage was 69.9%.

According to Mariele Morandin Lopes, immunologist at the Brazilian Association of Allergy and Immunology, the greatest risk of the population not being vaccinated is the return of some previously eradicated diseases. “We have seen a similar case with measles, which was also eradicated in Brazil, but due to low vaccination coverage we have had new cases recently”, she says. For the doctor, the various scientific studies and years of experience indicate that the benefits vastly outweigh any possible risk of the vaccine.

“The possibility of preventing a serious illness is infinitely better. The cases of children who have a contraindication to any vaccine are exceptions. Some examples are children who have a severe compromise of the immune system, with low production of antibodies”, he explains.

“In addition to protecting their children, they will be doing an act of love in indirectly protecting those children who have some immunodeficiency and have a real contraindication to vaccinate”, completes the doctor.

To try to reverse this situation, the Ministry of Health carries out an act of vaccination against polio and other diseases in Brasília, on Saturday (24) in the morning. During the event, actions to measure blood pressure, diabetes testing, integrative practices and other guidelines are planned to promote prevention and health promotion to the population.


For the multi-vaccination campaign, the vaccines available are: hepatitis A and B, penta (DTP/Hib/Hep B), 10 valent pneumococcal, VIP (Inactivated Poliomyelitis Vaccine), HRV (human rotavirus vaccine), meningococcal C (conjugate), OPV (oral polio vaccine), yellow fever, triple viral (measles, rubella, mumps), tetraviral (measles, rubella, mumps, chickenpox), DTP (triple bacterial), chickenpox and quadrivalent HPV (human papillomavirus).

The HPV, dT (double adult), yellow fever, triple viral, hepatitis B, dTpa and meningococcal ACWY (conjugated) vaccines will be available for adolescents. The Ministry of Health reinforces that all immunizers that are part of the National Immunization Program (PNI) are safe and are approved by the National Health Surveillance Agency (Anvisa).

As the vaccination campaigns coincide with the ongoing immunization against Covid-19, the ministry recommends that coronavirus vaccines can be administered simultaneously or with any interval with the others on the national calendar, in the population from 3 years old. deity.

The increase in vaccination coverage aims to increase protection against vaccine-preventable diseases, preventing outbreaks and hospitalizations, sequelae, rehabilitation treatments and deaths.
