Scientific advisers to the Centers for Disease Control and Prevention unanimously decided the benefits outweigh the risks for children Covid Vaccines for Very Young Children under 5 despite some reservations about thin data on efficacy, and the agency’s director signed off on the shots.
The Centers for Disease Control and Prevention on Saturday recommended Covid vaccines for children as young as 6 months, who were among the last Americans to qualify for the shots. Parents should be able to start getting young children immunized as soon as Tuesday. Federal regulators now have authorized the Moderna vaccine for children ages 6 months through 5 years, and the Pfizer-BioNTech vaccine for children ages 6 months through 4 years. (Pfizer-BioNTech’s vaccine has been available to children ages 5 and older since November.)
All children 6 months and older, including those who have already been infected with the coronavirus, should get a Covid vaccine, Dr. Rochelle P. Walensky, the C.D.C.’s director, said in a statement. “Together, with science leading the charge, we have taken another important step forward in our nation’s fight against Covid-19,” she said. “We know millions of parents and caregivers are eager to get their young children vaccinated, and with today’s decision, they can.” Following meetings on Friday and Saturday, the agency’s scientific advisers strongly backed the vaccines, despite reservations about the paucity of data, especially regarding the efficacy of the Pfizer-BioNTech vaccine.
The C.D.C. panel heard evidence supporting the effectiveness of the Covid Vaccines Young Children , but repeatedly pressed Pfizer on its estimates and noted that three doses of that vaccine would be needed, compared with two doses of the Moderna vaccine. Both vaccines are safe, and both produced antibody levels similar to those seen in young adults. But the C.D.C. advisers wrestled with the difficulty of recommending two very different vaccines for the same population.
“The implementation of these two rollouts is going to be incredibly challenging,” said Katelyn Jetelina, a public health expert and author of the widely read newsletter “Your Local Epidemiologist.” “There’s going to have to be a lot of proactive communication about the difference between the two and the implications of taking one over the other,” she said. In its clinical trials, Moderna found that two shots of its vaccine, each with one-fourth of the adult dose, produced antibody levels that were at least as high as those seen in young adults.
The company estimated the vaccine’s efficacy against symptomatic infection at about 51 percent among children ages 6 to 24 months, and 37 percent among children ages 2 through 5. The side effects were minor, although about one in five children experienced fevers. Efficacy against severe disease and death is assumed to be higher, similar to the effects seen in adults. Based on those data, the F.D.A. authorized two shots of the Moderna vaccine, spaced four weeks apart.
The vaccine has an overall efficacy of 80 percent in children under 5, Pfizer’s scientists claimed on Friday. But that calculation was based on just three children in the vaccine group and seven who received a placebo, making it an unreliable metric, the C.D.C.’s advisers noted. “We should just assume we don’t have efficacy data,” said Dr. Sarah Long, an infectious diseases expert at Drexel University College of Medicine. But Dr. Long said she was “comfortable enough” with other data supporting the vaccine’s potency. Three doses of the Pfizer vaccine produced antibody levels comparable to those seen in young adults, suggesting that it is likely to be just as effective.
The Pfizer vaccine was authorized for children 5 to 11 in November, but fewer than 30 percent in that age group have received two shots. In surveys conducted by the C.D.C., about half of parents said in February that they would vaccinate their children, but by May, only one-third of parents said they intended to do so. The advisers debated whether vaccination enhances protection against severe disease in children who have already been infected. There is little information available from children aged 5 to 11, because of the poor uptake of vaccines in that age group.
