Valneva’s share price jumped more than 20 percent on November 10 after the French vaccines company won European Commission approval for a deal under which it would supply up to 60 million doses of the COVID-19 vaccine candidate VLA2001 over two years.

Valneva SE on Oct. 18 said the company’s experimental Covid-19 vaccine demonstrated efficacy “at least as good, if not better” than AstraZeneca’s shot in a late-stage trial comparing the two, with significantly fewer adverse side effects.

French specialty vaccine company Valneva and U.S. drugmaker Pfizer reported positive results from the companies’ Phase II study on a vaccine candidate for Lyme disease.

CanSino Biologics Inc.’s single-dose Covid-19 vaccine – given at a lower dosage than that for adults – is safe and triggers an immune response in children aged 6-17, results from a small trial showed.

French vaccine maker Valneva is expanding trials of a Covid-19 vaccine candidate called VLA2001, and remains in talks with the European Commission over a potential contract, the company said on Sept. 23.

Valneva SE commenced rolling submission for initial approval of the company’s COVID-19 vaccine candidate VLA2001 with the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom.

Valneva SE announced the initiation of a further Phase 3 trial (VLA2001-304) for the company’s inactivated, adjuvanted Covid-19 vaccine candidate VLA2001.

Antibody levels in people inoculated with CanSino Biologics’ (CanSinoBIO) single-dose Covid-19 vaccine fell by some 30 percent after six months, however a booster shot could offer a significant lift, a senior executive said on Aug. 5.

An inhalation version of CanSino Biologics’ Covid-19 vaccine is being tested in a Phase II clinical trial, Chief Executive Yu Xuefeng said on June 2.

China’s CanSino Biologics will initiate clinical trials of an experimental Covid-19 vaccine that is inhaled, instead of injected.
