After school Thursday, 12-year-old Abhinav pushed up his T-shirt sleeve and looked down as a needle pierced his left shoulder.
The Ohio boy is one of the first children allowed to receive a vaccine designed to protect against COVID-19. His father, Sharat, also joined the trial. After months of testing its COVID-19 candidate vaccine in adults, Pfizer recently lowered the age of participation to 16, aiming to include at least 3,000 older teens. On Thursday, Cincinnati Children’s Hospital inaugurated an even younger group, vaccinating its first two middle schoolers. Pfizer is the only one of the leading drug companies to allow minors into a vaccine trial.
Some pediatric vaccine experts say drugmakers and federal regulators should wait until the vaccines have been proven safe and effective in adults before moving to children. “If I were part of the FDA I would certainly want to be very convinced about the safety of a vaccine before I approved its use in children,” Dr. Cody Meissner a pediatric infectious disease expert at Tufts Children’s Hospital said Thursday at a public meeting of an advisory panel to the U.S. Food and Drug Administration. “The pattern of disease is very different in children, and lumping them in with adults would cause me some discomfort.” But Dr. Barbara Pahud, director of research in the infectious diseases department at Children’s Mercy Hospital in Kansas City, Missouri, said it’s immoral not to get kids into trials as soon as possible.
“We should not allow children to die,” she said. “That’s our job as pediatricians to make noise and make sure people are noticing.”
Although most children recover well from COVID-19, they can pass the virus to their parents, teachers and grandparents, so it’s important to get them vaccinated, said Dr. Robert Frenck Jr., director of the Vaccine Research Center at Cincinnati Children’s Hospital Medical Center. Last week, Frenck dosed his first minor with the Pfizer vaccine, and Thursday marked the first younger volunteer.
At least 500,000 American children have contracted COVID-19 this year, Frenck said, and probably a lot more. “We’re not necessarily identifying all the times when the younger ones are transmitting to parents and grandparents,” he said.
Less than 1% of those children ended up hospitalized, Meissner said, so any vaccine given to children has to meet a high bar for safety to outweigh any risks. “I worry that the vaccines … in genetically predisposed children may elicit a very troublesome reaction,” said Meissner, a member of the FDA advisory panel that met for eight hours Thursday to discuss COVID-19 vaccine development.
But Pahud noted more than 100 children – many who were previously healthy – have died from COVID-19. That’s nearly as many as died in the last year from the flu, which saw a particularly deadly year. Others have developed a dangerous immune overreaction.
