The companies studied a 10 microgram vaccine dose in children 5 to 11, a third of the dose used for adults, to minimize side effects and because it still prompts a strong immune response.
The Food and Drug Administration also gave an OK to boosters that differ from the vaccine originally used to immunize people against COVID-19. A mix-and-match approach could ease the booster rollout.
A panel of experts voted to recommend that the Food and Drug Administration authorize a booster dose of the Johnson & Johnson COVID vaccine at least two months after the first shot.

Many transplant centers require people with alcohol-related liver disease to remain sober for half a year, before becoming eligible for the waiting list for a liver. But this thinking may be changing.
Scientists have created detailed maps of the brain area that controls movement in mice, monkeys and people. The maps could help explain human ailments like Alzheimer's and Lou Gehrig's disease.
Fatal drug overdoses, including from meth, have soared. California is preparing to roll out a controversial but proven treatment that involves paying stimulant users small sums of money not to use.
In a first, doctors injected the gene-editing tool CRISPR directly into cells in patients' eyes. The experiment helped these vision-impaired patients see shapes and colors again.
The pop star was forced into psychiatric care — and compelled to pay for it. That could happen to anyone during an episode of serious mental illness, adding a financial threat to the health woes.
Intensive rehabilitative therapy that starts two to three months after a stroke may be key to helping the injured brain rewire, a new study suggests. That's later than covered by many insurance plans.
Scientists are still studying whether the deworming medicine could have any effect on COVID-19. But the frenzy over the drug has far more to do with politics than science. Here's how that happened.
The visual problem is usually treated in kids by temporarily covering the other eye with a patch. But that doesn't always work. Research now shows crucial brain rewiring can happen in adulthood, too.
The rate of new cases of COVID-19 among babies and children under 4 years old in the U.S. recently surpassed the rate of new cases among adults older than 65. Here's how to protect newborns.
