Vaccine makers have been working on a transition to a commercial market in the U.S. by next year, as White House COVID-19 Response Team coordinator Dr. Ashish Jha said Tuesday the U.S. government will stop buying treatments, tests and vaccines by this fall.

"My hope is that in 2023, you're going to see the commercialization of almost all of these products. Some of that is actually going to begin this fall, in the days and weeks ahead. You're going to see commercialization of some of these things," Jha said at a U.S. Chamber of Commerce Foundation event.

Tests have already been available commercially at pharmacies, grocery stores and online, and treatments — those that remain effective — are pivoting to commercialization for 2023.

Of the four vaccines available in the U.S., only two have regulatory approval to go commercial: Moderna (MRNA) and Pfizer/BioNTech (PFE/BNTX).

Both companies have U.S. government orders for booster doses this fall, and are only planning to transition out after those doses have been delivered — but have not determined details such as price of doses, coverage by insurers, and details of how to transition logistics away from the government partnership.

Moderna, by comparison, said it is already working on commercialization.

"The commercial organization has already engaged with commercial payers and the channel, both channel distributors as well as key pharmacies, in anticipation of this shift. Internationally, we expect public health authorities to remain key purchasers of vaccines but we are also identifying markets where there may be a private commercial market as well," Arpa Garay, chief commercial officer, said during an earnings call this month.

Novavax (NVAX), which only just got emergency use authorization and is filing for booster approval in adults, and Johnson & Johnson (JNJ), do not have approval.

Novavax said it intends to pursue full approval by then end of 2022 and pricing will "be similar to the premium-priced influenza market in the U.S."
