Experts Warn That Reduction in Childhood Vaccination in the U.S. May Increase Epidemiological Risk and Favor Infectious Diseases.

In recent days, a decision made in the United States has reignited the global debate on childhood vaccination, public health, and epidemiological risk.

The U.S. government announced the withdrawal of six vaccines from the recommended vaccination schedule for children.

The measure, announced this week, worries doctors and experts, including in Brazil, as it may increase the circulation of infectious diseases in an increasingly interconnected world.

Childhood Vaccination and the Change in the U.S. Vaccination Schedule

The decision came from the Centers for Disease Control and Prevention (CDC), the agency responsible for public health guidelines in the United States.

In practice, this shifts responsibility to parents. Furthermore, the U.S. does not have a universal public system like Brazil’s SUS.

Therefore, many families will have to pay for the vaccines, which are costly, potentially reducing adherence to childhood vaccination even further.

Public Health Under Pressure and Lack of Scientific Evidence

One of the most critical points, according to Andréa Jácomo, is the lack of scientific basis for the withdrawal of the vaccines. “This time, there are no studies justifying the withdrawal,” she stated.

Historically, global public health has advanced with broad vaccination strategies.

One example cited by the specialist is the eradication of polio, which began in the 1980s with the famous “drops,” an oral vaccine with attenuated virus. This model saved millions of lives around the world.

Infectious Diseases: Proven Impacts of Vaccination

Among the withdrawn vaccines, the one against hepatitis B is considered one of the most sensitive.

The disease can be transmitted from mother to baby during childbirth.

After the introduction of the vaccine, there was an 89% reduction in cases in just one year, a result that no single medication can achieve.

Another example is the immunization against bronchiolitis caused by respiratory syncytial virus.

Rotavirus and Avoidable Costs for Health Systems

The withdrawal of the rotavirus vaccine is also concerning.

Even being a wealthy country, these hospitalizations generate high costs.

In Brazil, the experience has been positive.

In 2006, the introduction of the vaccine in the public system significantly reduced hospitalizations and deaths from childhood diarrhea, reinforcing the importance of childhood vaccination as a public health policy.

Meningitis, Measles, and Global Epidemiological Risk

The meningococcal vaccine is also at the center of the debate.

Brazil has recorded an increase in cases, even in the Federal District.

In 2025, the country reported over nine thousand cases of meningitis and more than a thousand deaths.

“The scenario changed completely after the vaccine was incorporated in 2010,” recalled Andréa Jácomo. Still, she warns that copying foreign models can be dangerous.

In the U.S., for example, measles has become a concern again, with more than two thousand cases and three deaths in the last season.

In Brazil, previous outbreaks have shown that a drop in vaccination coverage has direct effects. In 2018, the Northern region reported over nine thousand cases and 12 deaths, mainly among unvaccinated children.

Alert from Medical Entities and the Need for Vigilance

Thus, the decision by the U.S. was classified as dangerous and unnecessary by the American Academy of Pediatrics. In Brazil, the Brazilian Society of Pediatrics and the Brazilian Society of Immunization also expressed concern.

According to specialists, the epidemiological risk increases as the circulation of people intensifies.

In a globalized world, the message is clear: protecting childhood vaccination is protecting the public health of all.

Alert from Medical Entities and the Need for Vigilance

Scientists enter a narrow, flooded cave 500 meters deep and find giant dinosaur footprints on the ceiling measuring up to 1.25 meters, preserved in such a rare way that a new type of trace had to be created.

A giant half-ton ring fell in Kenya from space, and more than a year later, scientists still do not know where it came from.

In Botswana, a salt flat of up to 16,000 km² that was once an African megalake spends months as an absolute white desert, but during the rainy season it transforms into a shallow sea that reappears from nowhere and can be seen from space in the middle of southern Africa.

Seen from space, an image taken by an astronaut shows an unlikely oasis in the Saudi Arabian desert, protected by a terrain that slows the advance of sand, surrounded by green circles, remnants of an extinct lake and nearly 10,000 years of preserved history.

Map reveals how the Earth may look in 250 million years: continents will reunite in the Last Pangaea, 92% of the planet could become uninhabitable for mammals, and Spain appears among the rare possible exceptions.

About 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland, with houses forming a continuous row and narrow agricultural strips emerging behind them, creating one of the most unusual rural patterns in Europe.

With 1,000 buses sent abroad, the Brazilian manufacturer consolidates the strength of national technology and takes on a leading role in public transportation across all of Latin America.

Lula’s government will reduce Brazilian families’ debts with discounts of up to 90%; minister reveals when Lula will announce the program.

The secret of the paçoca that millions consume is not in the sugar; it starts with the selection of the peanuts, goes through machines that analyze each grain, and eliminates any health risks.

Invasive tree from China becomes a pest in Brazil: species up to 15 meters tall already occupies 20 hectares, over 700 trees removed in SP, and the risk of a “disastrous effect” mobilizes Ibama with drones and urgent action.

It seemed like just a mansion swallowed by weeds, but it hid a surreal collection with a dusty Ferrari F355, crowded garages, old tractors, abandoned boats, and dozens of cars rotting in silence.
