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.
LONDON – The U.K has started the world’s first trial alternating an adenoviral vectored COVID-19 vaccine with one that delivers the virus spike protein instructions encoded in messenger RNA. The heterologous prime boost trial will recruit 820 participants into an eight-arm study comparing different combinations of the Astrazeneca plc/Oxford University and Pfizer Inc./Biontech SE vaccines, administered in a different order and at different intervals.
While the Biden administration’s America Rescue Plan began its journey through Congress Feb. 3 as the next U.S. effort to address the COVID-19 pandemic, lawmakers came together to identify steps to improve vaccine distribution and curb ongoing supply shortages.
Vaxart Inc. investors who stuck by company shares Feb. 3 had to swallow a bitter pill – watching shares of the oral vaccine developer (NASDAQ:VXRT) fall 57.8% to $9.85. Driving the trade in part was news that, during a phase I trial, neutralizing antibodies to SARS-CoV-2 were not detected in most of the five subjects given two doses of VXA-CoV2-1, its oral recombinant protein vaccine for the potential prevention of SARS-CoV-2 infection. Furthermore, the company concluded it was "unable to evaluate" a study of the candidate organized by Operation Warp Speed.
Pfizer Inc. reported solid earnings for 2020 and said it expects even bigger things this year as the company projects approximately $15 billion in earnings from the COVID-19 vaccine it co-developed with Biontech SE.
CAJICA, Colombia - Colombia approved two different phase II/III trials for COVID-19 vaccine candidates over the last week, advancing one candidate developed by Germany’s Curevac AG and another by China’s Clover Biopharmaceuticals Inc.
LONDON – Two new U.K. studies point to long-term persistence of COVID-19 antibodies after both natural infection and vaccination, conferring protection against subsequent infection for at least three months.
As solid efficacy data are reported for at least four more front-runner vaccines, and while biopharma companies join arms with combination antibodies, SARS-CoV-2 variants continue to spread and countries are racing to vaccinate. None of the research is slowing, and governments are determined to make sure another COVID-19 pandemic never again takes the world by surprise. Global deaths are up to 2.2 million, with 102.9 million confirmed cases, according to the World Health Organization. At least 865 therapeutics and vaccines to fight the virus have entered development in the last year.
LONDON –The Russian COVID-19 vaccine Sputnik V now has validation from the Western science establishment, after The Lancet published full interim results of the phase III trial on Feb 2. The peer-reviewed paper confirms the 91%-plus efficacy that the vaccine’s developer, Gamaleya National Center of Epidemiology and Microbiology, claimed in its own announcement of the results in December.
DUBLIN – Amid a bitter dispute between the European Commission (EC) and Astrazeneca plc over supplies of the latter’s SARS-CoV-2 vaccine, the EC’s drug regulator, the EMA, recommended approval of the product in question, COVID-19 Vaccine Astrazeneca (formerly AZD-1222).
