More than 21 months since the SARS-CoV-2 virus was first identified in Wuhan, China, the questions just keep coming, and the longer they go unanswered, the more divisive the opinions become. Controversies over the efficacy of current vaccines, over whether boosters are necessary for the general population, over the safety of COVID-19 vaccines for young children, over how to distribute the shrinking supply of highly effective monoclonal antibodies, and over how the virus originated in the first place – all of these looming questions have created a firestorm of uncertainty that will not stop burning.
When the SARS-CoV-2 virus first emerged in the U.S., the knee-jerk reaction by biopharma researchers was to make the best vaccines and therapeutics possible and to do so quickly. Since then, the number of those that have entered development has reached 1,001, more than for any other viral infection aside from HIV.
Horseshoe or Rhinopolus bats in Laos carry coronavirus species with a near-identical receptor binding domain to SARS-CoV-2, according to a paper posted on the preprint server Research Square by investigators from the Pasteur Institutes of Paris and Laos.
Autumn's arrival in the Northern Hemisphere on Sept. 22 swept in significant news of progress for the global fight against COVID-19. A protein-based COVID-19 vaccine candidate from Clover Biopharmaceuticals Ltd. and Dynavax Technologies Corp. appeared wholly effective in preventing severe disease and hospitalization, sending Dynavax shares (NASDAQ:DVAX) climbing 26.5% to close at $18.79 on Sept. 22. In another study of Gilead Sciences Inc.'s Veklury (remdesivir), the drug significantly reduced hospitalization in high-risk patients with COVID-19. Meanwhile, governments and companies continued to expand efforts to supply new vaccines and therapeutics against the disease even as efforts continued far and wide to evaluate the efficacy of new and emerging candidates in both categories.
Sinovac Biotech Ltd. said booster shots of its Coronavac vaccine against SARS-CoV-2 induce strong immune responses in adult and elderly populations following a considerable loss of antibodies six to eight months after completing the current two-dose regimen.
The world has been running an ultramarathon since the COVID-19 pandemic began, but despite the ups and downs of cases and deaths, the wins and losses of clinical efforts, every day is another step forward toward herd immunity and the finish line.
The lack of data surrounding the efficacy of Chinese COVID-19 vaccines against the Delta variant has had many questioning them, especially after a recent study showed that one of those vaccines, Sinovac Biotech Ltd.’s Coronavac, was less effective than Pfizer Inc. and Biontech SE’s Comirnaty in Chile.
HONG KONG – The Biden administration’s support for a TRIPS waiver of COVID-19 vaccine patents has already met a chorus of resistance from Western companies. In Asia, skepticism about how it would be achieved and what it will cover, is widespread.
HONG KONG – Celltrion Inc. has received the European CE mark for Tekitrust, its COVID-19 tests kit developed with Mico Biomed Co. Ltd. “Mico, which is a diagnostic device specialist, partnered with Celltrion to combine both companies’ strengths in the test kit sector,” a Celltrion spokesperson told BioWorld. Mico will manufacture the kits, while Celltrion handles marketing and sales.
HONG KONG – Laboring under the burden of a new wave of COVID-19 infections that have raised its case total to 15.3 million, second only to the U.S., India is ramping up its vaccination efforts by opening up COVID-19 vaccine availability to citizens 18 years or older from May 1, according to the Ministry of Health and Family Welfare. However, ensuring a steady vaccine supply for the world's second most populous country, with nearly 1.4 billion people, might prove to be an issue. So far, India has administered just over 124 million COVID-19 vaccine doses.
