Although research is being conducted on Long COVID or Long COVID-19, whose symptoms continue for weeks and months after initial infection, there are very few ongoing clinical trials on treatments.

In response to the ongoing Russian invasion of Ukraine, Pfizer will cease operations within Russia and proceeds from the company’s subsidiary in that country will be donated to provide direct humanitarian support to the people of Ukraine. Regarding COVID-19, Pfizer Chief Executive Officer Albert Bourla noted in an interview with Face the Nation that it is likely that a fourth booster shot of the company’s vaccine will be needed to fend off another surge of infections.

The U.S. Food and Drug Administration is expected to announce that the regulatory agency is authorizing the use of a booster shot for the Pfizer-BioNTech and Moderna mRNA COVID-19 vaccines in some immunocompromised patients. 

U.S. Surgeon General Vivek Murthy stood by federal guidance that those fully vaccinated against Covid-19 no longer needed to wear masks, while blaming social media companies for fueling vaccine misinformation.

Health agencies and vaccine and immunology experts have pushed back against Pfizer and BioNTech’s assertions that a Covid-19 booster shot is necessary.
