Even after a number of the emerged nations declaring that they were on the verge of coming up with a vaccine to Coronavirus, it is an open fact that the clinical tests take at least 5-6 months. On this note, the World Health Organisation(WHO) made a shocking statement which triggered debates in the global health circles.
Cautioning that there may never be a vaccine for Corona, WHO envoy Dr David Nabarro, who also serves as a professor at Imperial College London stated that future has the scope of witnessing more viruses like Corona. “We can’t make an absolute assumption that a vaccine will appear at all, or if it does appear, whether it will pass all the tests of efficacy and safety,” he added.
He also stated that it has been a challenge to develop vaccines for common rhinoviruses and adenoviruses, which, similar to the coronavirus, can cause cold symptoms. “Only one vaccine prevents two strains of adenovirus, and it’s not commercially available,” he said. It was confirmed that more than 90 COVID-19 vaccines are underway, in various stages, by research teams in companies and universities worldwide.
