Danger: Children in Brazil get polio because they don’t get the vaccine

10 years in the past, Zé Gotinha acquired a robust ally to maintain polio away from Brazilian youngsters: the inactivated vaccine in opposition to poliomyelitis, whose intramuscular injection is taken into account simpler and safer than the well-known drops that eradicate the illness in Brazil and lots of elements of the world. . Nevertheless, the decades-old anniversary of this vaccine in the National Immunization Program (PNI) in August of this yr is being remembered with concern by researchers and well being authorities: whereas the illness has re-emerged in some elements of the world, the vaccine protection in opposition to polio in Brazil has elevated from the purpose of defending 95% of youngsters. far-off

The inactivated polio vaccine was launched in 2012 with two doses, however was expanded to a few doses in 2016. PNI recommends that they be administered at 2, 4 and 6 months of age, which gives immunity that’s solely strengthened at 15 months. and 4 years, with oral vaccine drops.

According to the National Immunization Program Information System (SI-PNI), the predicted dose of inactivated polio vaccine final reached the goal in 2015, when there was 98.29% protection of youngsters born that yr.

After 2016, protection fell beneath 90%, reaching 84.19% in 2019. In 2020, the Covid-19 pandemic affected the protection of a number of vaccines and this immunizer reached solely 76.15% of youngsters. In 2021, which may nonetheless publish information in the system, the proportion was beneath 70% for the first time, with 69.9%.

If the nation’s proportion signifies a scenario the place three out of 10 youngsters will not be vaccinated, the scenario could also be worse in regional readings. In the south the proportion is 79%, in the north 61%. According to the information panel, the worst performing state is Amapa, with solely 44% of youngsters vaccinated.

Agence Brasil contacted the Ministry of Health for touch upon the decline in polio vaccination protection and methods to reverse it, however there was no response at the time of scripting this report. In a place on the identical situation launched in February, the ministry stated it conducts communication actions all through the yr, not simply throughout vaccination campaigns, to strengthen info on the security and efficacy of vaccines as a public well being measure.

Polio free space

Brazil has not detected a case of poliomyelitis since 1989, and in 1994, it acquired certification from the Pan American Health Organization (PAHO) as an space free of untamed poliovirus circulation in the complete Americas.

According to the World Health Organization, the international victory over illness via vaccination has lowered the variety of instances worldwide from 350,000 in 1988 to 350,000 in 2018. Wild poliovirus at present is endemic solely in restricted areas of Central Asia, whereas in 1988 there was a world well being disaster in 125 endemic international locations.

the threat

As vaccine protection has declined in the Americas, the Pan American Health Organization (PAHO) has listed Brazil and 7 different Latin American international locations as high-risk areas for the illness to return. The warning comes in a yr when Malawi(, Africa , once more reported a case of untamed poliovirus, and New York City, USA, reported a case of poliomyelitis with paralysis in an grownup who had not traveled overseas.


Infectologist Luisa Helena Faleiros Arlant factors out that poliovirus an infection is usually asymptomatic, however it may be extreme and trigger irreversible and deadly paralysis, since in addition to the limbs, polio may paralyze the muscle mass answerable for respiratory. In this case, the affected person’s survival might rely upon the use of respirators.

“There is just one solution to stop polio, and that’s via vaccination. But with so few vaccinations, there are extra vulnerable individuals. If now we have about 3 million dwell births a yr, and if our vaccination charge is 60%, now we have about 40% of the 3 million are unvaccinated,” warned the physician, who’s the president of the Polio Technical Chamber of the Ministry of Health and a member of the Brazilian Society of Immunization (SBIM).

Infectologists famous that three doses of intramuscular vaccine shield youngsters in opposition to three serotypes of poliovirus, whereas the drops immunize in opposition to two of them. Parents who missed the second of this vaccine or delayed any of the three doses, specialists advise that they instantly return to the put up the place the vaccination schedule was interrupted.

“If a toddler has had one vaccination and does not get one other dose for 3 years, they need to get a second dose and, two months later, a 3rd dose. No one begins the routine once more, they need to proceed the place they left off. And Continue with intramuscular vaccine”stated the physician.


Luisa Helena Faleiros believes that the causes for declining vaccine protection are multifaceted. They vary from coaching major well being unit employees in order that vaccination alternatives will not be missed and speaking about vaccination every time households go to the put up for the dwelling situations of youngsters answerable for vaccination.

“Places should open, in specific, from 7 a.m. to 7 p.m., because at present you rely upon work like by no means earlier than, and to lose a day of labor at present is to lose a plate of meals on the desk. You can’t demand that employees cease incomes. Should. Money to help a household with the fundamentals to go to a well being heart. Still go there to search out out the vaccine has run out or the vaccine hasn’t arrived and have to return again the subsequent day”.

A researcher at the Immunobiological Institute of Technology (Bio-Manguinhos/Fiocruz) since 1970, Akira Homma participated in the improvement of a vaccine in opposition to poliomyelitis in Brazil, which was decisive for the eradication of the illness. Current vaccine protection is alarming even in a rustic that’s self-sufficient in intramuscular vaccine manufacturing in a partnership between Fiocruz and pharmaceutical firm Sanofi.

“When we used the attenuated virus vaccine to eradicate polio in the Nineteen Eighties, there was a nationwide vaccination day involving the complete Brazilian group and volunteers at hundreds of well being posts, vaccinating 18 million youngsters below the age of 5 in two or three days. was performed“, he remembers. “I don’t know if we’ll ever get that dynamic once more, because the moments are totally different, the priorities are totally different, however now we have to discover a message, because the message that is being despatched isn’t reaching the individuals, it isn’t. Reaching the inhabitants.”

According to scientists, the eradication of polio brought on the inhabitants to lose worry and curiosity in the illness, which had already been a supply of dread for households round the world all through the twentieth century.

“Populations at present assume that they are already protected, however they will not be”, He stated, who recommends that yet one more dose of inactivated vaccine in opposition to poliomyelitis be included in the immunization schedule for kids and that an epidemiological investigation be performed to learn how the immunity of adults receiving solely the oral vaccine is.
