Universities in China’s Greater Bay Area have developed a recombinant receptor-binding domain (RBD) protein vaccine candidate that has shown promise against COVID-19, researchers said Monday at a press conference in Hong Kong. The vaccine can induce neutralizing activity after seven days with one dose, but more animal studies are now underway to test its durability.

The issue of the U.S. federal government’s response to the COVID-19 pandemic was revisited yet again in a hearing in the House of Representatives. While partisanship was on full display, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said he is “cautiously optimistic” about the prospects for a vaccine and that the development of candidates has not compromised scientific principles.

In deals worth billions, Sanofi SA and Glaxosmithkline plc (GSK) have made new agreements this week to supply the U.S. and U.K. governments with a COVID-19 vaccine. The two companies also are in advanced discussions with the European Union to supply up to 300 million doses of a vaccine.

NEW DELHI – If India’s government has its way, the country could launch a vaccine for COVID-19 in mid-August, an extremely short deadline that has caused controversy and pushed companies to speed up their development and the trials of prospective vaccines.

Six months to the day that the World Health Organization (WHO) declared it a public health emergency, the SARS-CoV-2 virus, with its hideous red spikes, continues to taunt the world, hopping from host to host and haunting humans, many of whom wonder the same thing: What’s next?

Unraveling the eagerly awaited data from Genocea Biosciences Inc.’s phase I/IIa study with neoantigen cancer vaccine GEN-009 turned out less than simple, and the rollout of results – characterized by the company as positive, albeit early – were followed by a haircut for shares (NASDAQ:GNCA), which closed at $3.45, down $1.52, or 31%.

The U.S. government will pay $1.95 billion to Pfizer Inc. and Biontech SE for the first 100 million doses of their jointly developed mRNA-based COVID-19 vaccine once Pfizer manufactures it and receives the FDA’s approval or emergency use authorization. The two companies agreed, as part of Operation Warp Speed, to begin delivering 300 million doses of a COVID-19 vaccine in 2021.

LONDON – There were encouraging results from trials of three COVID-19 vaccines on July 20, with Astrazeneca plc, Biontech SE/Pfizer Inc. and Cansino Biologics Inc. all reporting T-cell responses in ongoing phase I/II studies of their respective products.
