The Food and Drug Administration is shelving plans to let more younger adults get second COVID-19 boosters this summer. Instead, officials are planning to speed up availability of the next generation of boosters in the fall, three administration officials confirmed to NPR.

The new strategy came after a debate within the administration about trying to balance protecting people this summer with keeping people safe next winter, when the country will probably get hit by yet another surge, according to the officials familiar with the discussion.

Some officials wanted to launch a new booster campaign this summer to encourage more people to get boosted and more boosted people to get double-boosted to protect them against the highly contagious BA.5 subvariant driving a surge this summer.

But others worried that would interfere with a booster campaign in the fall with what will hopefully be a superior booster specifically targeting BA.5.

One concern was that giving two boosters so close together could increase the risk for a rare heart inflammation called myocarditis. Another concern was that giving them so close together could blunt the protection from the second booster.
