Chinese researchers launch phase-2 human test for possible coronavirus vaccine
- The phase-2 trial will determine the shot's dose and continue to evaluate whether the potential vaccine can safely trigger immune responses in healthy people
(BEIJING) Chinese researchers have started a second phase human trial of a possible coronavirus vaccine, the Institute of Medical Biology at Chinese Academy of Medical Sciences (IMBCAMS) said on Sunday, in efforts to further assess effectiveness and safety.
About a dozen vaccines are in different stages of human tests globally, as the World Health Organization warns the coronavirus pandemic is accelerating and "the world is in a new and dangerous phase".
However, none of the vaccine trials have passed large-scale, late-stage phase 3 clinical trials, a necessary step before getting regulatory approval for sale.
IMBCAMS began on Saturday a phase 2 human test for its experimental shot, which is among six possible vaccines Chinese scientists are testing in humans, following an on-going phase-1 study that has recruited about 200 participants since May, the institute said on Sunday in its social media channel.
The phase-2 trial will determine the shot's dose and continue to evaluate whether the potential vaccine can safely trigger immune responses in healthy people.
IMBCAMS said it expects to use a plant dedicated to producing a coronavirus vaccine this year to prepare for China's future vaccine supplies.
