Pfizer announced on Tuesday that its Covid pill was found to stave off severe disease in a key clinical trial and that it is likely to work against the highly mutated Omicron variant of the virus. The results underscore the promise of the treatment, which health officials and doctors are counting on, to ease the burden on hospitals as the United States braces for a mounting fourth wave of the pandemic.

If the Food and Drug Administration authorizes the drug, which could happen within days, then patients might begin receiving it by the end of the year. Although supply will be limited at first, public health experts are hopeful that the pills might curb the worst outcomes from the disease, no matter the variant.

Public health authorities in Denmark and Norway on Monday released grim projections for the coming wave of the Omicron coronavirus variant, predicting that it will dominate both countries in a matter of days. Although scientists don’t yet know how often the variant causes severe disease, they say its rapid rate of spread will lead to an explosion of cases and could potentially increase pressure on hospitals, even if it proves to be mild.

The reports follow similarly worrisome findings from England released over the weekend, although researchers caution that the trend could change as the variant comes into clearer view. It’s not yet certain how often Omicron infections will send people to the hospital, or how many hospitalized patients are likely to die. And while Omicron can partly evade immune defenses, researchers have yet to determine how well vaccinations and previous infections will protect people against severe disease.

A report out of South Africa offered a first glimpse at how vaccinated people might fare against the fast-spreading Omicron variant of the coronavirus.

Laboratory experiments found that Omicron seems to dull the power of the Pfizer-BioNTech vaccine, but also hinted that people who have received a booster shot might be better protected.

As the world worries that the Omicron coronavirus variant may cause a surge of cases and weaken vaccines, drug developers have some encouraging news: Two new Covid-19 pills are coming soon, and are expected to work against all versions of the virus.

The Food and Drug Administration is expected to soon authorize a pill made by Merck and Ridgeback Biotherapeutics, called molnupiravir, which reduces the risk of hospitalization and death from Covid-19 by 30 percent if taken within five days of the onset of symptoms.
