WASHINGTON (BLOOMBERG) - The US government anticipates that it will stop purchasing and providing Covid-19 shots as soon as January due to a lack of funds, leaving Americans to obtain vaccines through insurers or pay for them out-of-pocket.

US health officials convened a meeting of more than 100 representatives from drugmakers, state and local health departments, health providers and insurers on Tuesday (Aug 30) to discuss the government's plans to transition sales of Covid-19 vaccines and therapeutics to the commercial market, according to Dawn O'Connell, who heads the Health and Human Services Department's Administration for Strategic Preparedness and Response.

Since the pandemic began, the US government and pharmaceutical companies have discussed shifting away from federal procurement of Covid-19 shots and drugs to commercial sales, just as seasonal flu shots are currently distributed.

The long-awaited shift could mean Americans may soon face costs for Covid-19 shots from Pfizer and Moderna, among other products.

"We have always intended to transition this work to the commercial market and have been planning for that transition for some time now," O'Connell wrote on Tuesday in a blog post. "Unfortunately, the timeline to make the transition has accelerated over the past six months without additional funds from Congress to support this work."

It's been 530 days since the US government received new funding for the Covid-19 response, O'Connell said.

The US also expects to stop paying for Covid-19 treatments such as Pfizer's Paxlovid in mid-2023 as supply runs out, she said.

Talks stalled

Bipartisan talks regarding new Covid-19 funds have remained stalled for months. House Democrats blocked US$15 billion (S$21 billion) in new pandemic funds over concerns it would come from state aid.

Later, Senate Republicans refused to support a US$10 billion package, citing objections to the Biden administration's immigration policies.

Funding is urgently needed for next-generation Covid-19 shots, therapies and tests, O'Connell said.

The US has bought 171 million doses of modified Covid-19 vaccines tailored to better protect against Omicron and its sub-variants. Those booster shots are expected to be cleared for use later this week and offered to people for free, as they have been throughout the pandemic.

Though the supply won't be enough to give shots to every adult, it could meet early demand. Pfizer and Moderna didn't immediately respond to request for comment.

The vaccine makers have charged the US government between US$15 and US$30 per dose, depending on the size of the supply agreement.

O'Connell said additional Covid-19 funding would "allow for an orderly wind down of the federal government's procurement and distribution programmes".

The US has already begun to transition certain Covid-19 products to the commercial market due to a lack of funds.

Earlier in August, Eli Lilly & Co. announced that it would sell its Covid-19 antibody treatment directly to health providers, states and territories in a bid to keep the drug available as US government funding and purchases dried up. The product's list price was US$2,100 per dose, the drugmaker said then.

Other Covid treatments will soon be sold commercially, according to the post.

The US expects to run out of AstraZeneca's Evusheld as soon as early 2023, followed by Merck & Co.'s Lagevrio in the first or second quarter of next year, O'Connell said.
