There are currently nearly 200 potential COVID-19 vaccine candidates in development, including 42 under clinical evaluation and 151 under pre-clinical evaluation, according to a report by the World Health Organization published on October 2.
On Monday, U.S.-based Johnson & Johnson announced a pause on all of its COVID-19 vaccine candidate clinical trials due to an “unexplained illness” in one of its study participants.
French pharmaceutical company Sanofi is hoping to have its vaccine candidate rolled out by mid-next year, according to Olivier Bogillot, its chief executive officer.
“We are in a very concrete environment at the regulatory level. We ourselves have signed a charter with various laboratories so as not to compromise on the safety of the vaccine. If the vaccine is effective and it is safe, yes, the next year, in mid-year, the French will be able to be vaccinated,” Bogillot said Tuesday.
Last week, U.S. Secretary of Health and Human Services Alex Azar said: “Pending FDA [Food and Drug Administration] authorizations, we believe we may have up to 100 million doses by the end of the year—enough to cover especially vulnerable populations—and we project having enough for every American who wants a vaccine by March to April 2021.”
Here we take a closer look at some of the latest COVID-19 vaccine developments.
Last month, Sanofi and U.K.-based GlaxoSmithKline (GSK) announced they has begun a clinical trial of their COVID-19 vaccine candidate, aiming to reach a phase-three trial by December.
“The companies initiated a Phase 1/2 study on September 3 with a total of 440 subjects being enrolled, and anticipate first results in early December 2020, to support the initiation of a pivotal Phase 3 study before the end of the year,” Sanofi confirmed in a statement last month.
“If these data are sufficient for licensure application, it is planned to request regulatory approval in the first half of 2021. In parallel, Sanofi and GSK are scaling up manufacturing of the antigen and adjuvant respectively with the target of producing up to one billion doses in total per year, globally.”
Johnson & Johnson
Johnson & Johnson, whose vaccine candidate JNJ-78436735 is being developed by Belgium’s Janssen Pharmaceutical Companies, announced: “We have temporarily paused further dosing in all our COVID-19 vaccine candidate clinical trials, including the Phase 3 ENSEMBLE trial, due to an unexplained illness in a study participant.
“Following our guidelines, the participant’s illness is being reviewed and evaluated by the ENSEMBLE independent Data Safety Monitoring Board (DSMB) as well as our internal clinical and safety physicians.
“Adverse events—illnesses, accidents, etc.—even those that are
