US has enough COVID-19 vaccines for boosters, kids' shots

Virus Outbreak Vaccine Supply

MADISON, Wis. (AP) — With more than 40 million doses of coronavirus vaccines available, U.S. health authorities said they're confident there will be enough for both qualified older Americans seeking booster shots and the young children for whom initial vaccines are expected to be approved in the not-too-distant future.

The spike in demand — expected following last week's federal recommendation on booster shots — would be the first significant jump in months. More than 70 million Americans remain unvaccinated despite the enticement of lottery prizes, free food or gifts and pleas from exhausted health care workers as the average number of deaths per day climbed to more than 1,900 in recent weeks.

Federal and state health authorities said current supply and steady production of more doses can easily accommodate those seeking boosters or initial vaccination, avoiding a repeat of the frustratingly slow rollout of COVID-19 vaccines across the country early this year.

“I hope that we have the level of interest in the booster ... that we need more vaccines,” Colorado Gov. Jared Polis said Tuesday. “That's simply not where we are today. We have plenty of vaccines.”

Robust supply in the U.S enabled President Joe Biden this week to promise an additional 500 million of Pfizer's COVID-19 shots to share with the world, doubling the United States' global contribution. Aid groups and health organizations have pushed the U.S. and other countries to improve vaccine access in countries where even the most vulnerable people haven't had a shot.

Among the challenges states face is not ordering too many doses and letting them go to waste. Several states with low vaccination rates, including Idaho and Kansas, have reported throwing away thousands of expired doses or are struggling to use vaccines nearing expiration this fall.

While most vaccines can stay on the shelf unopened for months, once a vial is opened the clock starts ticking. Vaccines are only usable for six to 12 hours, depending on the manufacturer, according to the U.S. Food and Drug Administration.

Moderna vaccines come in vials containing 11 to 15 doses. Pfizer vials contain up to six doses and Johnson & Johnson vials five doses.

“We are going to see more doses that go unused over time,” said Wisconsin's health secretary, Karen Timberlake. “They come in multidose files. They don’t come in nice, tidy individual single-serving packages.”
