LONDON – The EMA’s safety committee has concluded that unusual blood clots with low blood platelets are a rare side effect of Johnson & Johnson Inc.’s COVID-19 vaccine and that a warning should be added to the label. The decision is based on all available evidence, which currently consists of eight reports from the U.S. of serious cases of thrombosis, one of which was fatal. All cases were in people under 60 years of age, and within three weeks after vaccination, the majority in women. One case occurred during the clinical trials.
As COVID-19 deaths across the globe top 3 million, with more than 1 million in Europe alone, the global demand is increasing for mRNA vaccines, even as sponsors of adenovirus vaccines push back against ongoing safety concerns. Last week, the World Health Organization’s (WHO) Regional Office for Europe reported that the confirmed COVID-19 death toll for the region had surpassed 1 million, with 1.6 million new cases being reported every week. More than 171 million doses of COVID-19 vaccines have been administered in the region, translating to nearly 13% of the European population receiving one dose and close to 6% completing both doses of the vaccines.
LONDON – The U.K. is moving on to the next phase of testing mixed dosing schedules for COVID-19 vaccines, launching a study in which it will assess the effect of using Moderna Inc. or Novavax Inc.’s products as the second dose in a heterologous prime boost trial.
The FDA and the CDC have jointly recommended a temporary pause in the further rollout of Johnson & Johnson Co.’s COVID-19 vaccine while they investigate six rare clotting cases in adults ages 18 to 48.
PERTH, Australia – The Australian government is recommending that Australians under 50 take the Pfizer Inc. COVID-19 vaccine due to the risk of rare blood clots associated with Astrazeneca plc’s COVID-19 vaccine (ChAdOx1-S). The move jeopardizes Australia’s vaccine rollout as it had planned for the majority of Australians to receive the Astrazeneca vaccine, which is being locally manufactured by CSL Ltd.
HONG KONG – In a surprisingly candid statement, the director of China’s Centers for Disease Control conceded that the efficacy of Chinese coronavirus vaccines is "not high" and may require improvements. George Gao, the director of China’s CDC, stated that Chinese vaccines “don’t have very high protection rates” at the National Vaccines and Health conference in the southwestern city of Chengdu on Saturday.
CAJICA, Colombia – Following the start of phase III trials for its COVID-19 vaccine, Soberana 02, Cuban researchers have started phase III trials for Abdala (CIGB-66), another vaccine candidate developed in the island country.
LONDON – The EMA has concluded that the rare cases of serious blood clots with low platelet counts seen after administration of Astrazeneca plc’s COVID-19 vaccine are caused by the vaccine, but said the benefits of its use continue to outweigh the risks. The possibility of cerebral venous sinus thrombosis and splanchnic vein thrombosis in the abdomen will now be listed as rare side effects and the EMA’s guidance to health care professionals will be updated.
Plans for a late-stage test of Valneva SE's COVID-19 vaccine candidate, clinical progress on a different vaccine from Novavax Inc. and advancement for two midstage therapies targeting the virus made clear April 6 that industry efforts to battle the pandemic remain in high gear.
Following the company’s COVID-19 manufacturing misstep, Emergent Biosolutions Inc. continued its struggle to rebalance as top-line data from a phase III study it participated in failed to hit its primary endpoints with statistically significant results. The data showed that adding anti-SARS-CoV-2 hyperimmunoglobulin to standard of care, inclusive of remdesivir, for hospitalized adult COVID-19 patients with symptoms for less than 12 days failed to provide clinical benefit when compared to standard of care plus placebo. The global, multicenter double-blind, placebo-controlled randomized study assessed the safety and efficacy of four immunoglobulin candidates, the SARS-CoV-2 immune globulin intravenous (human) (COVID-HIG) plus standard of care.
