LONDON – A third COVID-19 vaccine has turned in positive results in the phase III interim analysis, with Astrazeneca plc/Oxford University reporting an average of 70.4% efficacy across two dose regimens for AZD-1222. Significantly, efficacy increased to 90% in the prime-boost arm of the trial, in which volunteers received half a dose, followed by a full dose. In addition to greater protection, that will make supplies go further.

LONDON - The world’s first COVID-19 human challenge trial is due to start in London next year, after the government announced £33.6 million (US$42.5 million) funding for the project. In the initial phase, the aim is to establish the dose of SARS-CoV-2 needed to cause infection and to characterize the immune response to virus. That will lead on to tests of individual COVID-19 vaccines, in which volunteers will be challenged with the effective dose of SARS-CoV-2 one month after inoculation.
TORONTO – What’s the difference between an organ transplant container tucked under a paramedic’s arm and an ordinary beer cooler packed with ice? Surprisingly, not much, according to researchers at London, Ontario’s Western University. They’ve come up with a portable, temperature-controlled container that prevents spoilage of donor organs during transport to the operating room – and of potential vaccines.
DUBLIN – The Lancet Infectious Diseases has published the first clinical data on BBIBP-CorV, an inactivated whole virus vaccine directed against SARS-CoV-2.
