The 2022 Grammy Awards have been postponed due to the surge in COVID-19 cases linked to the omicron variant.

"After careful consideration and analysis with city and state officials, health and safety experts, the artist community and our many partners, thx have postponed the 64th Annual GRAMMY Awards Show," CBS and the Recording Academy said in a joint statement.

The statement continued, "The health and safety of those in our music community, the live audience, and the hundreds of people who work tirelessly to produce our show remains our top priority.  Given the uncertainty surrounding the Omicron variant, holding the show on January 31 simply contains too many risks."

A future date for the Grammys has yet to be announced.

This is the second year in a row that the Grammys has been postponed. Last year, the show was held in March after its original date was canceled in January.

The number of COVID-19 vaccinations in the U.S. has declined over the last three weeks despite the surging number of cases due to the omicron variant.

In the past, surges have driven Americans to get vaccinated. However, data from the Centers for Disease Control and Prevention shows the average number of total doses administered has fallen 42% since Dec. 14.

An average of 304,000 Americans are currently receiving their first dose every day and 165,000 are reaching "full vaccination" status.

This is a drop from three weeks prior, when 455,000 were getting their first dose every day and 402,000 were reaching "full vaccination" status.

Additionally, the average number of people receiving booster shots every day has declined to 623,000 from more than one million.

A total of 67.4 million eligible Americans -- aged five and older -- remain completely unvaccinated.
