Pfizer says its COVID-19 vaccine works in children ages 5 to 11

WASHINGTON (AP/WWLP) – Pfizer said Monday its COVID-19 vaccine works for children ages 5 to 11 and that it will seek U.S. authorization for this age group soon — a key step toward beginning vaccinations for youngsters.

The vaccine made by Pfizer and its German partner BioNTech already is available for anyone 12 and older. But with kids now back in school and the extra-contagious delta variant causing a huge jump in pediatric infections, many parents are anxiously awaiting vaccinations for their younger children. According to the American Academy of Pediatrics, about 29% of current COVID cases in the U.S. are among children.

22News spoke with local elementary school parents Monday morning to hear their thoughts. “That would be good. It can protect all the kids. Because we have a big family so we need the shot right now,” Leriam Pelaz told 22News. She has four children but only one has been eligible for the COVID-19 vaccine. “My oldest she already had the shot and she’s great right now.”

For elementary school-aged kids, Pfizer tested a much lower dose — a third of the amount that’s in each shot given now. Yet after their second dose, children ages 5 to 11 developed coronavirus-fighting antibody levels just as strong as teenagers and young adults, Dr. Bill Gruber, a Pfizer senior vice president, told The Associated Press.

“It’s not necessarily the most vulnerable groups but those are our kids, those are our babies, you want to keep them protected at any cost,” elementary school mother, Destiny Hurt told 22News. “I’m looking forward to it, hopefully the trials go smooth and we see some results sooner than later,” she continued.

The kid dosage also proved safe, with similar or fewer temporary side effects — such as sore arms, fever or achiness — that teens experience, he said.

“I think we really hit the sweet spot,” said Gruber, who’s also a pediatrician.

Gruber said the companies aim to apply to the Food and Drug Administration by the end of the month for emergency use in this age group, followed shortly afterward with applications to European and British regulators.

Earlier this month, FDA chief Dr. Peter Marks told the AP that once Pfizer turns over its study results, his agency would evaluate the data “hopefully in a matter of weeks” to decide if the shots are safe and effective enough for younger kids.

Many Western countries so far have vaccinated no younger than age 12, awaiting evidence of what’s the right dose and that it works safely in smaller tots. But Cuba last week began immunizing children as young as 2 with its homegrown vaccines and Chinese regulators have cleared two of its brands down to age 3.

While kids are at lower risk of severe illness or death than older people, more than 5 million children in the U.S. have tested positive for COVID-19 since the pandemic began and at least 460 have died, according to the American Academy of Pediatrics. Cases in children have risen dramatically as the delta variant swept through the country.

“I feel a great sense of urgency” in making the vaccine available to children under 12, Gruber said. “There’s pent-up demand for parents to be able to have their children returned to a normal life.”

A Kaiser Family Foundation poll found that 27%of parents with children five to 11 would vaccinate their children immediately once available. 33% said they would wait and see and 26% said they would never vaccinated their children. The other 11 percent say they would do it if required.

“I think its great. I think it’s about time. I would in a heartbeat,” Hurt said about vaccinating her child.

In New Jersey, 10-year-old Maya Huber asked why she couldn’t get vaccinated like her parents and both teen brothers have. Her mother, Dr. Nisha Gandhi, a critical care physician at Englewood Hospital, enrolled Maya in the Pfizer study at Rutgers University. But the family hasn’t eased up on their masking and other virus precautions until they learn if Maya received the real vaccine or a dummy shot.

Once she knows she’s protected, Maya’s first goal: “a huge sleepover with all my friends.”

Maya said it was exciting to be part of the study even though she was “super scared” about getting jabbed. But “after you get it, at least you feel like happy that you did it and relieved that it didn’t hurt,” she told the AP.

Pfizer said it studied the lower dose in 2,268 kindergartners and elementary school-aged kids. The FDA required what is called an immune “bridging” study: evidence that the younger children developed antibody levels already proven to be protective in teens and adults. That’s what Pfizer reported Monday in a press release, not a scientific publication. The study still is ongoing, and there haven’t yet been enough COVID-19 cases to compare rates between the vaccinated and those given a placebo — something that might offer additional evidence.

The study isn’t large enough to detect any extremely rare side effects, such as the heart inflammation that sometimes occurs after the second dose, mostly in young men. The FDA’s Marks said the pediatric studies should be large enough to rule out any higher risk to young children. Pfizer’s Gruber said once the vaccine is authorized for younger children, they’ll be carefully monitored for rare risks just like everyone else.

A second U.S. vaccine maker, Moderna, also is studying its shots in elementary school-aged children. Pfizer and Moderna are studying even younger tots as well, down to 6-month-olds. Results are expected later in the year.
