There are already 6 vaccines in the final phase of testing 1:58
(CNN Spanish) -
At least 29 vaccines against coronavirus are currently being tested in multiple human trials that are running simultaneously around the world.
Among these, six vaccines are being tested in seven phase 3 trials.
There are currently six vaccines in Phase 3, which is the last stage of human trials before they seek approval.
There are three from China, two developed by state-owned Sinopharm and one by the private Chinese company Sinovac Biotech.
One in the UK, produced in collaboration between the University of Oxford and AstraZeneca.
And two from the United States, one from the pharmaceutical giant Pfizer, in addition to the Moderna candidate.
Getting to this late stage of trials just six months after the discovery of Covid-19 is remarkably quick;
it would normally take at least six years, according to Professor Adrian Hill, director of the Jenner Institute at the University of Oxford.
