Back-to-school will be the deadliest test of childhood disease prevention in a generation

As measles cases hit a 35-year high and vaccination rates plummet, America’s children are walking into a viral war zone—and the medical establishment is sounding the alarm.

The yellow school buses are about to start rolling again. The backpacks are being packed. Parents are getting lunchboxes ready. And millions of germs are waiting to feast on the unprotected throats and lungs of American children returning to classrooms with the lowest vaccination rates in decades.

This is not hyperbole. It is a public health crisis the administration of President Donald Trump is making.

With the United States recording 2,371 measles cases through July 30 — already surpassing all of 2025’s total and reaching the highest level in 35 years — public health experts warn this back-to-school season could become the greatest test of childhood disease prevention in a generation.

Michigan health officials reported the first two U.S. fatalities from the ongoing outbreak of Trump’s explosive diarrhea-causing foodborne illness cyclosporiasis, which began earlier this year.

The CDC, the Food and Drug Administration (FDA), and public health authorities are investigating a 98-case Salmonella outbreak in 17 states, which has led to 26 hospitalizations.

The Perfect Storm

Declining vaccination rates among school-aged children have created a tinderbox. Among kindergartners, the measles, mumps and rubella vaccination rate has fallen from 95.2% during the 2019-20 school year to 92.5% during the 2024-25 school year, leaving an estimated 286,000 kindergartners without protection against measles, mumps and rubella.

“Measles, which can cause serious health issues or even death, can spread quickly in schools and as a consequence lead to lost instructional time,” health experts warn.

But measles is only part of the threat. Whooping cough. Mumps. Polio. Influenza. COVID-19. Respiratory syncytial virus. All remain capable of exploiting immunity gaps created by declining vaccination rates.

The Trump administration’s deep cuts to domestic and global health funding, along with scaled-back vaccine recommendations and unfilled leadership roles at major agencies like the CDC and NIH, have sparked serious worries among public health experts about climbing infection rates and weakened disease tracking.

More than half of the CDC’s 23 centers, institutes, and offices plus roughly half of the 27 separate institutes that make up the NIH are missing permanent directors and are being run by temporary acting heads.

Trump administration officials are celebrating the rollback of various scientific research grants and tracking systems, which critics argue weaken the nation’s defense against preventable diseases.

State legislators were flooded with more than 400 vaccine-related measures from August 2025 to July 2026, including 209 proposals aimed at weakening vaccination rules or eroding public trust in vaccines.

The proposals hit every part of the vaccination system, including school and daycare requirements, legal protections for unvaccinated people, mRNA and COVID-19 vaccines, and messaging that casts vaccines as dangerous. Only nine of the anti-science bills became law, and no state eliminated its core childhood immunization requirements, though Arizona and New Hampshire came close.

The Medical Community Responds

The American Medical Association has been unequivocal.

In a strongly worded statement, AMA President Dr. Bobby Mukkamala said: “There is no credible scientific evidence to support changing the current childhood vaccine schedule. That schedule is built on decades of rigorous research and real-world data.”

“Altering it without clear, evidence-based justification risks continued confusion for parents and patients, undermining trust in vaccines, and ultimately lowering vaccination rates. That would put more children and communities at risk of preventable illness,” Mukkamala said.

At the same time, political opposition to vaccine requirements continues.

In Florida, State Surgeon General Dr. Joseph Ladapo has called vaccine mandates “wrong” and “immoral,” saying: “What you put into your body is because of your relationship with your body and your God. I don’t have that right. Government does not have that right.”

Florida’s effort to eliminate vaccine requirements — which would make it the first state to remove mandates for vaccines against polio, measles, diphtheria, tetanus, pertussis and hepatitis B — has stalled but not ended.

The AMA has condemned the proposal as an “unprecedented rollback” that would “undermine decades of public health progress and place children and communities at increased risk for diseases such as measles, mumps, polio, and chickenpox, resulting in serious illness, disability, and even death.”

“For a president who upholds ‘Make America Healthy Again‘ as a load-bearing narrative pillar, Donald Trump has gone to remarkable lengths to make the US a breeding ground for a widening range of viruses, bacterium, and parasites — and no, we’re not talking about his cabinet,” writes Joe Wilkins. “Early into his second tenure as commander-in-chief, Trump and his cronies set to rapidly dismantling offices doing critical work on public health.”

The Kennedy Factor

Health and Human Services Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic with no medical or science degree, has removed the COVID-19 vaccine from the Centers for Disease Control and Prevention’s immunization schedule for healthy children and pregnant people.

In the absence of a clear federal policy during Trump’s first term, some state governors issued lockdown orders after hospitals reported that their ICUs were overrun and they needed some help, but Kennedy made claims that constitutional rights were violated during the pandemic and that those who were critical of the COVID-19 response were censored.

On January 19, 2021, Trump awarded Dr. Anthony Fauci a Presidential Commendation recognizing his work as part of Operation Warp Speed, the federal program created to develop those COVID-19 vaccines, but MAGA Republicans are now seeking to imprison the former chief White House medical adviser.

Six major medical organizations, including the American Academy of Pediatrics and the Infectious Diseases Society of America, have filed suit, arguing the directive represents “a pressing public health emergency that demands immediate legal action.”

Kennedy also dismissed all 17 members of the CDC’s Advisory Committee on Immunization Practices and appointed eight new members, several of whom have drawn criticism for their views on vaccines.

During their first meeting, the committee questioned evidence supporting vaccine use and voted that thimerosal — a preservative repeatedly found to be safe in scientific studies — should no longer be used in influenza vaccines.

“It was clear that there was an agenda with disinformation and misinformation,” said Dr. Jason Goldman of the American College of Physicians.

What the American Academy of Pediatrics Recommends

Amid the controversy, the American Academy of Pediatrics has released its 2026 Recommended Child and Adolescent Immunization Schedule for children and adolescents through age 18.

For respiratory illnesses, the recommendations include:

Influenza

• Annual vaccination for everyone 6 months and older.
• Available as inactivated, recombinant or live attenuated (nasal spray) vaccines.
• One or two doses annually, depending on vaccination history.

COVID-19

• Routine vaccination for previously unvaccinated children ages 6 to 23 months with two doses of Moderna Spikevax administered four to eight weeks apart.
• Additional doses for children ages 2 to 18 in high-risk groups.
• A single age-appropriate dose may be offered to children ages 2 to 18 who are not in high-risk groups if parents want additional protection.
• Moderately or severely immunocompromised children may require up to four doses.

Respiratory Syncytial Virus

• One dose of the RSV monoclonal antibody nirsevimab or clesrovimab during RSV season for eligible infants and young children, depending on maternal vaccination status.
• RSV vaccine (Abrysvo) for eligible populations.

Recommended Routine Childhood Vaccinations

The AAP’s schedule also includes:

• Hepatitis B at birth.
• Rotavirus beginning at 2 months.
• DTaP at 2, 4, 6 and 15 to 18 months, with a booster at ages 4 to 6.
• Haemophilus influenzae type b at 2, 4, 6 and 12 to 15 months.
• Pneumococcal conjugate vaccine at 2, 4, 6 and 12 to 15 months.
• Inactivated polio vaccine at 2, 4, 6 to 18 months and again at ages 4 to 6.
• MMR at 12 to 15 months and ages 4 to 6.
• Varicella at 12 to 15 months and ages 4 to 6.
• Hepatitis A at 12 to 23 months.
• Tdap at ages 11 to 12.
• Human papillomavirus vaccine at ages 11 to 12.
• Meningococcal ACWY vaccine at ages 11 to 12, with a booster at age 16.
• Meningococcal B vaccine at ages 16 to 18.

The Human Cost

The debate is not simply political. It has direct consequences for children’s health.

Dr. Kym Middleton, a pediatric hospitalist at Huntsville Hospital for Women & Children, said: “Every school year, we see an increase in common childhood illnesses as kids return to the classroom. The good news is that healthy habits at home can make a big difference.”

Healthy habits, however, cannot stop a measles outbreak in an under-vaccinated school. They cannot prevent a child from contracting pertussis because of declining vaccination coverage. Nor can they protect immunocompromised children who depend on high community vaccination rates for protection.

“One of the best ways parents can help stop the spread of illness is by keeping children home when they’re sick,” Middleton said.

What Parents Can Do

The AAP and CDC recommend that parents:

• Keep children current on recommended vaccinations.
• Encourage frequent handwashing for at least 20 seconds, cover coughs and sneezes, and regularly clean backpacks and lunchboxes.
• Keep sick children home until they have been fever-free for at least 24 hours without fever-reducing medication.
• Schedule annual wellness visits to ensure children remain current on immunizations and developmental screenings.

The Bottom Line

As students return to classrooms this fall, public health officials warn that declining vaccination rates have increased the risk of outbreaks of preventable diseases.

Medical organizations continue to recommend the routine childhood immunization schedule as the safest and most effective way to protect children and communities from serious infectious diseases.

“Vaccines are one of the most effective tools in modern medicine,” the AMA said. “Decisions about their use must be guided by science, patient safety, and the expertise of unbiased physicians and public health experts — not by policy shifts that erode confidence in proven protections.”
