Moderna announced Thursday that it is in the process of developing a new vaccine that combines a booster dose of its COVID-19 vaccine with a seasonal flu vaccine.

Why it matters: "We believe this is just the beginning of a new age of information-based medicines," CEO Stéphane Bancel said in the press release, which also gave a slew of updates on projects the company is pursuing.

Driving the news: “Today we are announcing the first step in our novel respiratory vaccine program with the development of a single dose vaccine that combines a booster against COVID-19 and a booster against flu," Bancel said.

  • The company has several flu shot candidates in development and the booster shot would combine the version furthest along in development with its already existing COVID-19 vaccine, per Reuters.
  • Moderna also said it is developing a vaccine for respiratory syncytial virus (RSV) and provided updates regarding its general COVID-19 booster shot trials.
  • Moderna's shares jumped more than 5% following the announcement, CNBC reported.

Of note: Novavax announced Wednesday that it is also developing a combination COVID-19 and flu shot, and that it has initiated a clinical trial of the potential new shot.

The new Omicron COVID-19 variant will "inevitably" be found in America, health officials say. Cases have already been reported in several countries in the days since it was identified.

Why it matters: National health experts say it’s not time to worry, but it is time to get vaccinated if you’re not already, or get a booster shot.

Biden: Fight against Omicron won't include "shutdowns or lockdowns"

President Biden on Monday said that the new coronavirus variant, Omicron, is "a cause for concern, not a cause for panic."

Driving the news: Biden said later this week the administration will be releasing a strategy on how "we're going to fight COVID this winter. Not with shutdowns or lockdowns, but with more widespread vaccinations, boosters, testing and more."

Federal court blocks Biden's vaccine mandate for health workers in 10 states

A federal court in Missouri has blocked the Biden administration from enforcing a coronavirus vaccine mandate for health care workers at federally funded facilities in 10 states.

Why it matters: Monday's decision is the first victory for opponents of the rule, which requires health care workers to get vaccinated by Jan. 4, 2022. The case is one of four lawsuits challenging the Centers for Medicare & Medicaid Services' (CMS) rule and argues that the mandate will exacerbate staffing shortages.
