In a bid to build public confidence and demonstrate its transparency in determinations about potential COVID-19 vaccines, the FDA will convene its Vaccine Advisory Committee for a virtual meeting Oct. 22 to discuss the general development of the vaccines for the U.S. market.

With COVID-19, questions about how infections cause lasting immunity, or don’t, and how you know and what it all means for vaccines have become a matter of public focus. But some immunologists have been pondering those questions for years. “The immune system has a very good memory,” Bali Pulendran told BioWorld. “Clearly, some viruses and some pathogens can enter the body and stimulate the immune system, and the immune system can remember that encounter for decades.”

Advanced talks between the European Commission and Curevac AG have positioned the company to potentially supply up to 405 million doses of its investigational mRNA-based COVID-19 vaccine to the bloc. News of the progress, following similar EU-level talks with an alliance of Sanofi SA and Glaxosmithkline plc, Johnson & Johnson and Astrazeneca plc, sent Curevac's recently-listed U.S. shares (NASDAQ:CVAC) climbing 16% to $66 on Aug. 20.

Avoiding the political overtones that seem to be more viral than COVID-19 these days, Anand Shah, deputy commissioner for medical and scientific affairs at the FDA, stressed that even though the agency is making decisions in real time in response to the urgency of the pandemic in the U.S., its decisions are being driven by scientific integrity, regulatory independence and the FDA’s historic commitment to ensuring the safety and efficacy of the products it regulates.

PERTH, Australia – As Victoria suffers through a second COVID-19 wave, bringing the death toll to 430 for Australia, Prime Minister Scott Morrison said that Australians could be among the first in the world to receive a COVID-19 vaccine through an agreement with Astrazeneca plc. Under the deal, every Australian would be able to receive AZD-1222, which is being developed with the University of Oxford.

Chinese state-backed vaccine developer China National Biotec Group (CNBG), of Beijing, published an interim analysis of randomized phase I/II trials of its inactivated SARS-CoV-2 vaccine candidate in the Journal of the American Medical Association last week.

Reports out of Russia that the country approved a COVID-19 vaccine came with more questions than answers, as some in the rest of the world fretted over the apparently paltry degree of testing. Though the product has not completed phase III trials – human research thus far has involved only two groups of volunteers of 38 people each – Russia President Vladimir Putin is said to have declared Gam-COVID-Vac adequately studied.

With strong results in hand from the phase I stage of its phase I/II study testing a would-be COVID-19 subunit vaccine, Novavax Inc.’s president of R&D, Gregory Glenn, said “it’s possible we could go down in the dose” as work proceeds and get similar efficacy.

Universities in China’s Greater Bay Area have developed a recombinant receptor-binding domain (RBD) protein vaccine candidate that has shown promise against COVID-19, researchers said Monday at a press conference in Hong Kong. The vaccine can induce neutralizing activity after seven days with one dose, but more animal studies are now underway to test its durability.
