Coronavirus Update: Omicron-targeting COVID boosters expected this week, but experts are worried there may be low uptake


The Food and Drug Administration is expected to authorize new COVID-19 booster shots this week that target the latest versions of the omicron variant but will do so without data from a study showing the shots were safe and worked in humans.

Clearance of the doses, without data from human testing known as clinical trials, is similar to the approach the FDA takes with flu shots, which are updated annually to keep up with mutating flu viruses, as the Wall Street Journal reported.

“Real-world evidence from the current mRNA COVID-19 vaccines, which have been administered to millions of individuals, show us that the vaccines are safe,” FDA Commissioner Robert Califf said in a recent tweet.

Perhaps the bigger challenge once the boosters are available will be uptake, given that Congress has not agreed to release the billions of dollars needed to pay for distribution and rollout at vaccine sites, as the New York Times reported.

The federal government ran out of money this spring to reimburse shots given to uninsured people. At the same time, local health officials have reduced their outreach to unvaccinated people and most of the country is behaving as if the pandemic is over. Local authorities are also being distracted by the effort needed to contain a monkeypox outbreak and new cases of polio.

The overall COVID vaccine program has more or less stalled for the past several months with numbers provided by the Centers for Disease Control and Prevention barely budging from week to week.

U.S. known cases of COVID are continuing to ease, although the true tally is likely higher given how many people are testing at home, with data not being collected.

The daily average for new cases stood at 88,391 on Sunday, according to a New York Times tracker, down 14% from two weeks ago. The daily average for hospitalizations was down 10% at 38,252, while the daily average for deaths is down 2% to 478.

While those numbers are well below the peaks seen in late 2021 and early 2022, it still means the country is suffering 9/11 level casualities every six days or so.

Meanwhile, time is running out for Americans to get their allotment of free COVID-19 tests from the government.

The program is set to be suspended Sept. 2 — which is this Friday — or even sooner, if supplies run out, according to a message on the COVID test website.

Every U.S. household is eligible for eight free rapid antigen tests per order, for a total of 16 free tests. The program started in January, offering four tests per household, then later expanded in March and May.

Anyone who has not used their allotment can still order them in the coming days by signing up online at, or by calling 1-800-232-0233. The tests are free, and there are no shipping costs.
