Researchers working at the Duke University Medical Center report on a breakthrough in UTI vaccine development in the March 1, 2021, issue of the Proceedings of the National Academy of Sciences.
Chengdu-based Sichuan Clover Biopharmaceuticals Inc., known for its Trimer-Tag technology, raised $230 million in a series C financing round. The proceeds will, most notably, help it advance its COVID-19 vaccine candidate, S-Trimer (SCB-2019), to a global phase II/III trial by June. Following its $43 million series B round in December 2019, Clover said on Tuesday, Feb. 23, that it raised more than $400 million in the last 12 months. The company uses its Trimer-Tag technology platform to produce covalently-trimerized fusion proteins to develop protein-based vaccines and biologic cancer therapies.
HONG KONG – China is steadily greenlighting more COVID-19 vaccines and drugs to go deeper into the clinic, giving the country a growing arsenal against the disease. To date, China’s National Medical Products Administration (NMPA) has approved a handful of drugs and 16 domestically developed COVID-19 vaccine candidates for trials, up from 11 in September 2020.
COVID-19 vaccine developers should begin testing their vaccines against emerging variants now and assessing booster regimens, the FDA said in an update to its October guidance on emergency use authorizations (EUAs) for the vaccines.
PERTH, Australia – Australia’s Therapeutic Goods Administration (TGA) has granted provisional approval to Astrazeneca Pty Ltd. for its COVID-19 vaccine, a recombinant adenovirus vaccine, making it the second COVID-19 vaccine to receive regulatory approval in Australia, following the Jan. 26 provisional approval for Pfizer Australia Pty Ltd.’s COVID-19 vaccine, branded Comirnaty.
LONDON – A follow-up study of participants in the phase II/III U.K. trial of Astrazeneca plc’s COVID-19 vaccine has shown it remains effective against the new B.1.1.7 variant of SARS-CoV-2.
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.
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.”
NEW DELHI – India is taking a multipronged approach to developing and distributing vaccines against COVID-19, with at least 10 different products under development, domestically or through collaborations with foreign developers. Vaccinations are likely to begin early next year but, with a population of around 1.2 billion, it is unlikely India will be able to vaccinate everybody it needs to before the end of 2022.
Following a recent string of emergency use authorizations (EUA) for their jointly developed COVID-19 vaccine, BNT-162b2, Pfizer Inc. and Biontech SE said Dec. 14 that results from an ongoing German trial have helped illustrate "the multiple arms of the immune system that are activated" by the product to fight SARS-CoV-2. Separately, Moderna Inc. raised to 200 million the number of doses of its COVID-19 vaccine candidate it will supply to the U.S. government.
