An advisory panel to the U.S. Centers for Disease Control and Prevention (CDC) is meeting on May 19 to discuss whether to recommend COVID-19 vaccine booster shots for children ages 5 to 11, a group that is just 29% vaccinated so far.

In a peer-reviewed study published May 17 in PLOS Medicine, scientists found that mRNA-based COVID-19 vaccines were superior to adenovirus vector-based ones across major variants of the SARS-CoV-2 virus.

The United States will share technologies used to make COVID-19 vaccines through the World Health Organization and is working to expand rapid testing and antiviral treatments for hard-to-reach populations, President Joe Biden said on May 12.

Just as Emergent BioSolutions looked to be making some headway in course corrections following a production mishap that ruined millions of doses of Johnson & Johnson’s COVID-19 vaccine, new information indicates the Maryland-based company sought to hide the deficiencies from federal regulators, all while touting its manufacturing capabilities, according to a BioSpace article.

In the early days of the COVID-19 pandemic, pulmonologist Joseph Varon offered an opinion that made headlines around the world and went viral on social media. Varon was fighting two wars, he said: one against COVID and one against stupidity.

COVID-19 vaccine makers are shifting gears and planning for a smaller, more competitive booster shot market after delivering as many doses as fast as they could over the last 18 months.

Severe obesity may weaken the effectiveness of COVID-19 vaccines in those who have never been infected with the coronavirus, according to a small Turkish study. Additionally, South African researchers have found infection with the Omicron variant of the coronavirus can significantly improve the immune system’s ability to protect against other variants, but only in people who have been vaccinated.

The Janssen COVID-19 vaccine is now limited to certain individuals ages 18 and up after the U.S. Food and Drug Administration downgraded its emergency use authorization.

Two new sublineages of the Omicron coronavirus variant can dodge antibodies from earlier infection well enough to trigger a new wave, but are far less able to thrive in the blood of people vaccinated against COVID-19, South African scientists found.

COVID-19 cases and deaths are declining in the Americas, the Pan American Health Organization (PAHO) said on April 20, with infections last week having dropped 2.3 percent and deaths falling 15.2 percent from the prior week. The broad trend comes even as cases have scaled up in North America with an 11.2 percent increase last week, the organization said.
