Pharmaceutical giant makes advances with new Covid vaccine

Sanofi and GlaxoSmithKline announced Monday that their coronavirus vaccine candidate produced powerful responses in a preliminary trial that followed an earlier setback in the vaccine’s development.

Sanofi and GlaxoSmithKline’s potential Covid-19 vaccine triggered strong immune responses in all adult age groups in preliminary trials after an earlier setback, boosting optimism the shot may join the fight against the pandemic this year.

After two doses of the vaccine candidate, participants showed neutralizing antibodies in line with those found in people who had recovered from the disease, according to results of the Phase 2 trial released Monday. The drugmakers said they plan to begin late-stage trials and production in the coming weeks and hope to win regulatory approval for the vaccine before the end of 2021.

Overall, the vaccine candidate elicited strong neutralizing antibody levels that were comparable to those generated by natural infection, with higher levels observed in younger adults (18 to 59 years old).

After a single injection, high neutralizing antibody levels were generated in participants with evidence of prior SARS-CoV-2 infection, suggesting strong potential for development as a booster vaccine.

“Our Phase 2 data confirm the potential of this vaccine to play a role in addressing this ongoing global public health crisis, as we know multiple vaccines will be needed, especially as variants continue to emerge and the need for effective and booster vaccines, which can be stored at normal temperatures, increases”, said Thomas Triomphe, Executive Vice President and Global Head of Sanofi Pasteur.

“With these favorable results, we are set to progress to a global Phase 3 efficacy study. We look forward to generating additional data and working with our partners around the world to make our vaccine available as quickly as possible,” he added.
