The CDC now says healthy kids don’t need COVID shots. Is that true?

The Centers for Disease Control and Prevention will no longer advise that healthy children receive routine COVID-19 shots, a significant departure from its previous approach of suggesting annual shots for everyone age 6 months and older.

Health Secretary Robert F. Kennedy Jr. announced the change on the social platform X on Tuesday, citing a lack of data to support vaccines for healthy children. The move echoes his long-standing skepticism about the need to vaccinate children against the virus. Kennedy, who as health secretary oversees the CDC, has repeatedly said that children are at almost no risk from COVID.

It’s true that for many children, a case of COVID will be inconsequential. They might have a runny nose, a cough or other mild symptoms, if any at all, and bounce back within a few days. But some children do become seriously ill and, in rare cases, die from their infections. And data shows that more than 1 million U.S. children have developed long COVID.

That discrepancy is at the root of a continuing debate among medical researchers about just how much of a risk COVID poses to children, and whether they should receive annual vaccines against it.

Children might not benefit as much as adults would from a yearly shot because their immune systems can remember vaccinations for much longer, said Dr. Michael Mina, a former professor of epidemiology at the Harvard T.H. Chan School of Public Health who has extensively studied COVID. Another argument against annual shots is that most children in the United States now have some degree of protection from previous infections or vaccinations.

Those in favor of annual vaccines for children stress that protection from vaccines or infections wanes over time, especially as new variants emerge, so they can benefit from another dose. And emerging evidence shows that vaccination may protect against long COVID — although that is far from settled science.

“We know that COVID’s still out there. We can prevent it, and the vaccine has got no appreciable side effects,” said Dr. Chris Forrest, a professor of pediatrics at Children’s Hospital of Philadelphia. “So I think it’s a totally positive value proposition.”

This added protection may be especially important for children with underlying conditions, and for those who live with relatives who are older or at high risk of severe illness.

Ultimately, doctors said, the question comes down to how families make sense of the risk to their children. Here’s what the data shows.

How mild is COVID usually for children?

It is difficult to get good data on what share of pediatric cases are mild, but doctors say that most children develop few symptoms.

Some of the best information on children we have is from 2020, before children had built up widespread immunity from vaccination or infections. A review of studies from that year found that around 4% of children with COVID worldwide developed severe symptoms, which can include difficulty breathing, high fever and chest pain.

How likely is it that children will be hospitalized with or die from COVID?

Children who have COVID are generally at a low risk for hospitalization. About 234,000 children in the United States were hospitalized with infections between September 2020 and April 2024. Though the virus has led to milder disease over time, children and teenagers still accounted for about 4% of hospitalizations related to COVID between October 2024 and March 2025.

The risk is higher for babies younger than 6 months. From October 2022 to April 2024, young infants were more likely to be hospitalized than any other age group apart from adults 75 and older.

Pediatric COVID deaths are very rare.

Are only children with underlying health conditions falling seriously ill?

In an April appearance on Fox News, Kennedy said that some children with “very profound morbidities may have a slight risk” from COVID but that “most kids don’t.”

But CDC data from July 2023 to March 2024 found that half of children who were hospitalized because of COVID had no underlying medical conditions.

It is true that underlying health conditions like obesity, diabetes, heart disease and chronic lung diseases raise the risk of hospitalization. Children with these and other conditions will still be able to be vaccinated.

But the increase in risk isn’t small. Research has shown that young people with at least one underlying condition are 28% more likely than those with no underlying conditions to end up in critical care with COVID, and are 125% more likely to die from it. The more underlying conditions a child has, the greater the risk.

A review of data on 183 pediatric COVID deaths from 2020 to 2022 found that 32% of children who died did not have another medical condition.

Does vaccinating pregnant women protect infants?

Kennedy also announced Tuesday that the CDC will no longer recommend that healthy pregnant women be vaccinated against COVID. Pregnant women are at a far higher risk of severe disease from COVID.

Vaccinating pregnant women also reduces the risk that their infants will be hospitalized from COVID. Babies under 6 months are at higher risk of hospitalization from the disease, in part because their immune systems are so fragile, and they are not able to be vaccinated.

What about the risk of myocarditis?

Kennedy has claimed that COVID vaccines have “huge associations” with types of heart inflammation, called myocarditis or pericarditis. The shots have been linked to this issue in rare cases, particularly among adolescent boys. Most instances of myocarditis associated with vaccines have been mild. One analysis of nearly 4 million people who received booster shots found 28 instances of probable or confirmed myocarditis, all of which resolved quickly.

COVID-19 vaccines note the minor risk of heart inflammation to young men on their warning labels. Last month, the FDA told Pfizer and Moderna to broaden that warning to include boys and men between the ages 16 and 25, citing data that showed about 38 cases of heart inflammation per million doses among this age group.

Research has consistently shown that the virus itself is far more likely to cause this inflammation. One review found that the risk of myocarditis after infection was more than seven times greater than the risk after vaccination.

What’s the risk of long COVID?

Estimates of long COVID among children vary widely. But even at the lower end, studies show that around 1% of children in the United States, or roughly 1 million children, have ever had long COVID, broadly defined as symptoms that persist or emerge at least three months after an infection. These include many children who had mild or asymptomatic infections.

The condition commonly causes children to experience fatigue, dizziness, shortness of breath, and trouble concentrating and sleeping.
