European firms step up COVID-19 vaccines work, UK team starts human trials

LONDON/ROME (Reuters) - Scientists in Britain began clinical trials of a potential COVID-19 vaccine on Thursday as other vaccine developers across Europe also stepped up work on experimental shots against the disease caused by the new coronavirus.

 

A team at Britain's Oxford University dosed the first volunteers in a trial of their vaccine - called "ChAdOx1 nCoV-19" - while Italy's ReiThera, Germany's Leukocare and Belgium's Univercells said they were working together on another potential shot and aimed to start trials in a few months.

 

Britain's GSK <GSK.L> and France's Sanofi <SASY.PA> last week announced a similar agreement to develop a COVID-19 vaccine, with trials starting in the second half of the year.

 

As many as 100 potential COVID-19 candidate vaccines are now under development by biotech and research teams around the world, and at least five of these are in preliminary testing in people in what are known as Phase 1 clinical trials.

 

The Oxford scientists said last week that large-scale production capacity was being put in place to make millions of doses of the ChAdOx1 nCoV-19 shot, even before trials show whether it is effective.

 

They said on Thursday that the main focus of initial tests is "to find out if this vaccine is going to work against COVID-19, if it won’t cause unacceptable side effects and if it induces good immune responses".

 

ReiThera's chief technology officer Stefano Colloca told Reuters his three-way consortium's potential vaccine technology would allow for production to be rapidly scaled up from tens of thousands to millions of doses, and would also have a long shelf-life to ease distribution.

 

"We'll begin the trials in July. We have to add to the challenge of developing a safe vaccine for COVID-19 the important need to guarantee the production of millions of doses in record time", he told Reuters.

 

Charlie Weller, head of vaccines at the Wellcome Trust global health charity, said on Wednesday that to develop safe and effective COVID-19 vaccines to protect everyone as soon as possible, "the world needs to be prepared to execute the largest and fastest scale-up in vaccine manufacturing history".

 

A Swiss scientist said on Thursday he aimed to get ahead of industry projections that a COVID-19 vaccine will take 18 months, with a hope to put his laboratory's version in use in Switzerland this year.

 

Martin Bachmann, head of immunology at Bern's Inselspital hospital and founder of start-up Saiba Biotechaims, said he planned to begin human trials in August in 240 volunteers if he gets the necessary approval from drug watchdog Swissmedic.

 

Instead of using a weakened virus like some vaccines, Bachmann said his team had opted for a "virus-like particle" that mimics the coronavirus, only without its genetic material needed for replication.

 

Companies in China, where the disease is thought to have originated, are also working on potential vaccines.

 

The race for a vaccine has been fuelled by the shortage of options for treating the disease. The European Union's drug regulator on Thursday reiterated a warning against using two older malaria drugs outside of trials or national emergency use programmes, citing potentially lethal side effects.

Good luck to all of them. My money would be on the Brits. Those Oxford boffins know their stuff. Trial started on St Georges day; good omen.

Agree...leave the Yanks with their Trumpee disinfectant into the human body....suggest Jeyes Fluid trial on the Neanderthal POTUS.
