The World Health Organization on Monday hailed the “good news” of positive results from two Covid-19 vaccines that have proven safe for humans and have produced a positive immune response against the infection.
“It is good news,” Dr Michael Ryan, head of emergencies at the WHO, told a press briefing.
“We have 23 Covid-19 candidate vaccines in clinical development and as of today we have one candidate vaccine for which Phase I clinical data was available,” he said.
“It is great to see data coming through into peer-reviewed journals,” he added.
The statement comes in the light of two different studies published in Lancet.
The journal on Monday published Phase I results from AstraZeneca’s vaccine candidate developed in collaboration with Oxford University that had shown positive immune response. The trials consisted of 1,000 healthy volunteers.
In a second study, a Covid-19 vaccine candidate from China’s CanSino Biologics had also shown positive immune response for candidates in clinical trials.
“Both vaccine doses induced significant neutralising antibody responses to live SARS-CoV-2, with GMT of 19.5 & 18.3 in participants receiving high & low dose, respectively. Binding antibody response peaked at 656.5 & 571 ELISA units for high & low vaccine dose, respectively,” Lancet had tweeted.
Ryan emphasised the need for further trials on a larger scale to determine the efficacy of the vaccines.
“We now need to move into larger-scale real-world trials. But it is good to see more data and more products moving into this very important phase of vaccine discovery,” Ryan said.
Chinese researchers from CanSino Biologics published a study on their experimental vaccine,
Other front-runners of the vaccine race include US firm Moderna’s experimental vaccine, which will begin the next phase of trials on July 27. Meanwhile, a vaccine candidate under development by Pfizer Inc and Germany's BioNTech has also shown promise in early studies.
AstraZeneca will also be conducting a clinical study in India for its “promising” Covid-19 vaccine candidate.
“We will be doing a study in India. It’s a big country and there is a lot of infection,” AstraZeneca Chief Executive Pascal Soriot told BusinessLine.
