Eight months after Beijing-based Yisheng Biopharma Co. Ltd. unveiled its recombinant protein vaccine candidate for COVID-19, YS-SC2-010, the company raised $130 million in a series B round to pave way for the vaccine to enter clinical trials in the second quarter of this year, the company’s CEO David Shao told BioWorld.
Months of talks between Johnson & Johnson (J&J) and Merck & Co. Inc. about a COVID-19 vaccine manufacturing partnership came to fruition March 2 with the Biden administration hailing the deal as an “unprecedented historic” agreement between two long-time rivals.
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.
With several more emergency use authorizations (EUAs) across the globe, COVID-19 efforts to flatten the emerging variants with cocktail therapies and tweaked vaccines are frantically underway. BioWorld has tracked 884 therapeutics and vaccines that have entered development for the deadly SARS-CoV-2 virus since it first emerged more than a year ago, and the U.S. government has now provided EUAs to three vaccines and six therapies.
With the FDA’s granting of emergency use authorization (EUA) to Johnson & Johnson (J&J), there is now a third vaccine – and the first requiring only a single shot – against COVID-19 for adult Americans. Though it packs less of an efficacy punch, the EUA allows J&J’s Ad26.COV2.S to join mRNA vaccines from Moderna Inc. and Pfizer Inc./Biontech SE as protection against the virus.
A new study by Mayo Clinic and Nference Inc. researchers suggests that prior childhood and adult vaccinations for illnesses such as polio, measles and flu may provide protection against COVID-19 infection. The study, which analyzed patient data using Nference artificial intelligence (AI) software, underscores the critical role immunizations play in curbing the spread of diseases and preventing future pandemics. “What we discovered represents compelling evidence that vaccinations are a critical element in prevention of disease, even diseases one doesn’t anticipate,” said Venky Soundararajan, co-founder and chief scientific officer of the Cambridge, Mass.-based company.
China’s National Medical Products Administration granted conditional approval two Chinese-developed COVID-19 vaccines in less than 24 hours on Feb. 25. One of the vaccines approved was developed by Tianjin-based Cansino Biologics Inc., and the other by China National Pharmaceutical Group (Sinopharm) through its Wuhan Institute of Biological Products subsidiary.
As expected, the FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) looked favorably upon the latest COVID-19 entry: Ad26.COV2.S, a one-shot product that emerged from the same Johnson & Johnson (J&J) platform, AdVac, that let the firm devise an Ebola vaccine cleared in Europe last year.
The EMA issued a guidance Feb. 25 outlining the requirements for manufacturers planning to modify COVID-19 vaccines to address emerging variants of the SARS-CoV-2 coronavirus.
