HONG KONG – Shortly after Australia’s recent provisional approval for the mRNA-based COVID-19 vaccine Comirnaty (tozinameran), originally developed by Pfizer Inc. and Biontech SE, Hong Kong has approved it, too, for emergency use ahead of rivals developed in mainland China. It is the first vaccine to be approved in the Chinese territory, made possible through a collaboration between Biontech and Shanghai Fosun Pharmaceutical Group Co. Ltd.

PERTH, Australia – Australia’s Therapeutic Goods Administration (TGA) has granted provisional approval to Pfizer Australia Pty Ltd. for its COVID-19 vaccine, branded Comirnaty, making it the first COVID-19 vaccine to receive approval in Australia.

LONDON – There is “a realistic possibility” that infection with the B 1.1.7 variant of SARS-CoV-2 is associated with a 30% to 40% increased risk of death compared to earlier variants of the virus, according to scientists on the U.K. government’s New and Emerging Respiratory Virus Threats Advisory Group. That conclusion is based on studies by three university groups, linking community PCR testing to mortality.

LONDON – There’s mixed news about emerging variants of SARS-CoV-2, with Pfizer Inc. and Biontech SE reporting their vaccine Comirnaty maintains its protective effect against B 1.1.7, first detected in the U.K., while researchers in South Africa say virus variant 501Y.V2 is able to escape neutralization by both monoclonal antibodies and convalescent plasma from previously infected individuals.

Moncef Slaoui, chief advisor to Operation Warp Speed, the public-private partnership to hurry along a vaccine for COVID-19, cited tough going in the early days of development, as researchers met “a real challenge to engage the population.” During a panel discussion at the virtual 39th J.P. Morgan Healthcare Conference, he pointed to “a double-edged sword, to talk about what a vaccine can do, when we don’t know – and then once you know, you’re going to have to change your message.”

LONDON – Controversy has erupted over COVID-19 vaccines dosing after the U.K. said it is to prioritize giving as many people as possible a single dose of the two currently approved products, rather than two doses three or four weeks apart, as scheduled on their labels. The move prompted a sharp rebuke from FDA Commissioner Stephen Hahn and Peter Marks, director of FDA’s Center for Biologics Evaluation, who said any such change “is not rooted in the science.”

HONG KONG and BEIJING – China’s Sinovac Biotech Ltd. delayed releasing trial data from its Coronavac COVID-19 vaccine while the National Medical Products Administration (NMPA) accepted an NDA from China National Biotec Group (CNBG) for its own vaccine, BBIBP-CorV.

Hopes continue to rise as the COVID-19 vaccine beat goes on and Operation Warp Speed (OWS) lives up to its name, with Moderna Inc. netting another U.S. Department of Defense contract worth about $1.97 billion for another 100 million doses – an order that brings to about $6 billion the company’s government contracts for the product, which was granted emergency use authorization (EUA) earlier this month.

Thanks to Myovant Sciences GmbH’s potential $4.2 billion deal with Pfizer Inc. for recently approved Orgovyx (relugolix) in prostate cancer (PC), more physicians are going to be learning about [the compound] faster,” said chief commercial officer Adele Gulfo. “This is going to create huge demand.”
