AstraZeneca’s Phase III Provent trial results showed a statistically significant 77 percent decrease in a patient’s likelihood of developing symptomatic COVID-19 when proactively treated with Evusheld. Additionally, results were announced by Clover Biopharmaceuticals for the Phase II/III Spectra global study investigating the efficacy of the SCB-2019 (CpG 1018/Alum) vaccine booster in patients that have previously developed a COVID-19 infection.

A potential vaccine from China’s Clover Biopharmaceuticals was 67 percent effective against Covid-19 of any degree of severity and 79 percent against the highly infectious Delta variant in a large trial, the company said on Sept. 22.

As the world awaits the production and distribution of hundreds of millions of doses of COVID-19 vaccines that have been granted emergency use authorization, biopharmaceutical companies and manufacturers are developing the next wave of vaccines and therapeutics to combat the pandemic.
