Higher antibody titer levels were found in participants receiving two doses of Moderna Inc.’s COVID-19 vaccine compared to those receiving the Pfizer Inc.-Biontech SE vaccine, according to a research letter published in JAMA.
A closely watched phase IIb test of JNJ-9220, an investigational HIV vaccine regimen developed by Johnson & Johnson's Janssen Vaccines & Prevention BV, has been stopped because the regimen provided insufficient protection against HIV infection. Though safe, the candidate's efficacy was just 25.2%, according to statisticians who analyzed data from the study, called Imbokodo. Further analysis of the study will continue, and the study was deemed to have provided sufficient data for further immunological correlates research, according to J&J.
The CDC’s Advisory Committee on Immunization Practices (ACIP) heard a safety update on COVID-19 vaccines, took up the matter of booster shots, and voted on whether to recommend the vaccine from Pfizer Inc. and Biontech SE for people 16 and older, now that it’s fully licensed. Under an emergency use authorization, the vaccine can be given to people 12-15 years old.
With the Americas having the dubious distinction of the most COVID-19 cases in the world, the Pan American Health Organization (PAHO) is answering that “wake-up call” with plans to develop a collaborative platform to develop mRNA vaccine production in Latin America and the Caribbean.
Johnson & Johnson has announced new data supporting use of its COVID-19 vaccine as a booster shot, after separate trial data from the U.K. showed effects of several vaccines waned after six months.
Suzhou Abogen Biosciences Co. Ltd.’s $700 million series C fundraising provides tailwinds for the development of its messenger ribonucleic acid (mRNA) platform. The company plans to accelerate its COVID-19 mRNA vaccine clinical trial, develop other vaccine candidates and oncology programs.
Cadila Healthcare Ltd. (also known as Zydus Cadila) has received emergency use authorization (EUA) in India for Zycov-D, making it the world’s first plasmid DNA vaccine for COVID-19. Besides the adult population, the Drug Controller General of India’s nod has also given the South Asian country its first COVID-19 vaccine for adolescents ages 12 to 18.
As many lower and middle-income countries continue to scramble for COVID-19 vaccine doses, which are largely being manufactured in Europe and the U.S., their own regulatory rules may be getting in the way in some instances.
As talk increases of third doses of COVID-19 vaccine, a game-changing option is delivering them intranasally instead of intramuscularly. “It’s all about nasal carriage. It’s a better way to not carry the virus and not make others sick,” Bluewillow Biologics Inc. CEO Chad Costley told BioWorld. “The most important thing is that it’s safe.”
The quiet cancellation of an Aug. 24 meeting in which the U.S. CDC’s Advisory Committee on Immunization Practices (ACIP) was supposed to discuss COVID-19 vaccine boosters is raising more questions about whether the Biden administration got ahead of the data with its Aug. 18 announcement that it planned to roll out mRNA booster shots to adults beginning next month.
