LONDON – Initial results from the U.K. randomized trial assessing mixed COVID-19 vaccine schedules show there is a significant increase in systemic side effects with one dose of Astrazeneca plc’s and one of Pfizer Inc./Biontech SE’s vaccines (in either order), compared to receiving two doses of the same vaccine.

It came as no surprise May 12 that the CDC’s Advisory Committee on Immunization Practices (ACIP) voted 14-0, with one recusal, to recommend the use of Pfizer Inc.-Biontech SE’s COVID-19 vaccine, Comirnaty (tozinameran), in 12- to 15-year-olds following the FDA’s decision earlier this week to expand the vaccine’s emergency use authorization (EUA) to that age group.

A cautious optimism pervaded the March 11 Senate Health, Education, Labor and Pensions (HELP) Committee update on COVID-19, with witnesses and lawmakers alike welcoming the continuing decline of infections, hospitalizations and deaths in the U.S.

As expected, the FDA has expanded emergency use authorization (EUA) for Pfizer Inc. and Biontech SE’s COVID-19 vaccine, Comirnaty (tozinameran), to include adolescents 12 through 15 years of age, marking what Acting FDA Commissioner Janet Woodcock called "a significant step in the fight against the COVID-19 pandemic."

Novavax Inc. backed off its guidance of submitting an EUA for its COVID-19 vaccine in June, pushing the anticipated date to this fall. “We expect to complete regulatory filings in the third quarter,” Stan Erck, Novavax’s president and CEO, told investors on a May 10 conference call. “We hope to have market authorizations in multiple countries in the third quarter, as early in the quarter as possible.”

Amid what Moderna Inc. called "overwhelming" demand from global governments for mRNA vaccines and boosters with efficacy against SARS-CoV-2 variants of concern, the company said both its authorized vaccine, mRNA-1273, and a strain-matched candidate, mRNA-1273.351, increased neutralizing titers against the variants.

The Biden administration’s May 5 about-face on the proposed TRIPS waiver of intellectual property (IP) protections for COVID-19-related medical products is not playing well with U.S. industry, EU trading partners and others concerned about the long-term unintended consequences.

Once again, the World Trade Organization (WTO) postponed a decision on a temporary intellectual property (IP) waiver for COVID-19 vaccines and other related medical products.

Dangerous blood clots and thrombocytopenia, rare simultaneous side effects seen with two adenoviral vector vaccines from Astrazeneca plc and Johnson & Johnson, as well as a worldwide spike in COVID-19 cases and deaths, primarily in India, has set the stage for what could soon become the next big vaccine option, a protein subunit candidate from Gaithersburg, Md.-based Novavax Inc.
