The CDC released two studies on Thursday that showed the vaccine’s safety for ages 5-11 and highlighted the importance of immunizing children against the coronavirus to prevent serious illness. and hospitalized.
In one study, researchers found that children who received the Pfizer vaccine rarely had serious problems.
In another study, researchers looked at hundreds of children hospitalized since the summer and found that virtually all children with severe COVID-19 infections were not fully vaccinated.
“This study demonstrates that unvaccinated children hospitalized for COVID-19 can become seriously ill and reinforces the importance of immunizing all eligible children to protect themselves and their who are not yet eligible to be vaccinated,” the authors of the second study wrote.
According to The New York Times, nearly 9 million doses of the Pfizer vaccine have been given to ages 5-11 in the United States to date. In mid-December, or about 6 weeks after the age group became eligible for the October vaccination, the CDC said it had received very few reports of serious problems.
CDC researchers evaluated reports received from physicians and the public, including survey responses from parents and guardians of approximately 43,000 children ages 5-11. Many children reported non-serious events such as injection site pain, fatigue or headache, especially after the second dose.
Of the more than 4,100 adverse event reports received in November and December, 100 reported serious events, the most common of which were fever or vomiting.
The CDC has received 11 confirmed reports of myocarditis, or myocarditis, noted as a rare vaccine side effect in boys and men aged 12-29 years. Among them, 7 children have recovered and 4 children are still recovering at the time of reporting.
The CDC had received reports of 2 deaths – 5- and 6-year-old girls – with chronic illnesses and “in ill health” prior to the injection. The agency says there is no data to suggest a “causal link between mortality and vaccination.”
The CDC also received several reports that children 5-11 years of age received higher doses of the vaccines intended for older children and adults. Most reports say that the children did not have any problems after taking the incorrect dose.
In a separate study of childhood hospital admissions, CDC researchers looked at more than 700 children under age 18 who were hospitalized for COVID-19 in July and August at six children’s hospitals in Arkansas. , Florida, Illinois, Louisiana, Texas and Washington, DC
The researchers found that only one out of 272 vaccine-eligible patients between the ages of 12 and 17 were fully immunized, and 12 were partially vaccinated.
In addition, about two-thirds of hospitalized children between the ages of 12 and 17 have underlying medical conditions, the most common of which is obesity. About a third of children under the age of 5 are infected with the virus more than once.
Overall, the CDC researchers found, about 30% of children require treatment in intensive care units and 15% require invasive ventilation. Nearly 3% have childhood multisystem inflammatory syndrome, or MIS-C, which is a rare but serious inflammatory condition associated with COVID-19.
Of all children hospitalized with COVID-19, about 1.5% die.
“Few vaccine-eligible patients hospitalized with COVID-19 have been vaccinated, highlighting the importance of immunization for those aged 5 years and other prevention strategies to protect children and adolescents recovering from COVID-19, especially those with underlying medical conditions,” the study authors wrote.

The New York Times: “Covid vaccines rarely lead to problems in younger children, according to two CDC reports.”
