Operation Warp Speed, a federal effort supporting COVID-19 vaccine development, helped get multiple vaccines authorized for use in less than a year.

The FDA on Tuesday authorized a second booster dose of COVID-19 vaccine for people aged 50 years or older and certain immunocompromised patients, citing evidence that it improves protection against severe disease.

New COVID-19 guidance released by the CDC on Friday indicates that most Americans now live in areas where they can go maskless.

The interval between the first and second doses of the Pfizer-BioNTech and Moderna COVID-19 vaccines can be up to 8 weeks for certain people, the CDC said in updated interim guidance.

Prior SARS-CoV-2 infection protects against symptomatic reinfection with SARS-CoV-2 variants, including omicron, national data from Qatar showed.

Omicron has taxed the country’s health care system, causing more COVID-19 cases, ED visits and hospitalizations than any other variant during the pandemic, according to newly published data.

Six COVID-19 vaccines increased protection when given as booster shots 10 to 12 weeks after a two-dose primary series of the Pfizer-BioNTech vaccine, according to results from a randomized controlled trial published in The Lancet.

In this episode, Joel M. Gelfand, MD, MSCE, and Leonard H. Calabrese, DO, are joined by Carlos del Rio, MD, as they discuss the use of booster shots in the general population and in patients with underlying autoimmunity.
