Data from two Novavax Inc. clinical trials show its COVID-19 vaccine had 100% protection against severe disease, including hospitalization and death, paving the way for an emergency use authorization submission in the U.S. Mild and moderate COVID-19 was dramatically reduced in both studies, according to the data, and some efficacy was confirmed in variant strains.

What started with Austrian regulators suspending use of one batch of Astrazeneca plc’s COVID-19 vaccine has expanded into precautionary holds in Denmark and other EU countries as PRAC, the EMA’s safety committee, investigates whether blood clots, which have resulted in at least two deaths in Europe, are connected to the vaccine.

Positive COVID-19 efficacy numbers from Vir Biotechnology Inc. and Glaxosmithkline plc (GSK) has prompted them to immediately seek an emergency use authorization (EUA) with the FDA and similar authorizations in other countries for their monoclonal antibody, VIR-7831. Meanwhile, the phase III Remdacta study of Actemra/RoActemra (tocilizumab) plus Veklury (remdesivir) vs. placebo plus Veklury, from Roche Holding AG and Gilead Sciences Inc., missed its primary endpoint in treating hospitalized patients with severe COVID-19 pneumonia receiving standard of care.

As the World Trade Organization (WTO) debate intensified this week over a demand to waive patent protections for COVID-19 vaccines and therapies, the group’s new director-general, Ngozi Okonjo-Iweala, urged members to “walk and chew gum” at the same time by working with “companies to open up and license more viable manufacturing sites now in emerging markets and developing countries. We must get them to work with us on know-how and technology transfer now.”

KARACHI, Pakistan – Trypanophobia is a debilitating extreme fear of needles and syringes that prevents both children and adults from receiving sometimes life-saving medical care. The condition can lead patients to resist or deny simple procedures like an intravenous drip or even essential vaccinations. The condition has taken on an added significance in the fight against COVID-19 because of its impact on vaccination campaigns.

Shares of Paris-based Abivax SA (Paris:ABVX) fell 25.4% to €21 (US$25.07) on March 8 after the company said it would halt a phase IIb/III trial of its lead candidate, ABX-464, in high-risk COVID-19 patients for lack of efficacy. The decision was based on a data safety monitoring board analysis that Abivax said revealed a "lower than expected rate (10.1%) of progression to severe disease or death with no difference between ABX-464 and placebo groups," each of which also received standard-of-care therapy.

CAJICA, Colombia – Cuba’s Center for the State Control of Drugs, Equipment and Medical Devices gave the green light March 3 for phase III trials of a domestically developed COVID-19 vaccine candidate, even though very little peer-reviewed information has been published about it.

LONDON – The SARS-CoV-2 variant of concern that caused a wave of infection in Manaus, Brazil, in December and January has been found to be both more transmissible and to evade immunity conferred by prior natural infection with the virus. A combined Brazil/U.K. genome sequencing and epidemiological study found the variant, called P.1., is between 1.4 and 2.2 times more transmissible than earlier lineages, and can evade 25% to 61% of the protective immunity elicited by previous infection.
