World Health Organization (WHO) top scientist Dr Soumya Swaminathan said on Thursday that the organization is optimistic about the Covid-19 vaccine being available before the end of this year.

During a press conference in Geneva in the wake of ongoing medical trials on the treatment of corona virus treatment, Swaminathan said that it has been proved that the anti-malarial drug hydroxychloroquine prevented the deaths of hospitalized people after being infected with the corona virus.

I do not work in the context of future vaccines that protect against this deadly virus, he said that about 10 candidates are in the human testing phase and at least 3 of these candidates are entering a new phase where a vaccine proves to be effective.

Referring to the WHO’s effort on effective vaccines, Swaminathan said, “I hope.” I am hopeful, but developing vaccines is a highly complex process and there is also a lot of uncertainty. The good thing is that we have many different candidates and platforms.
He said that if we are lucky then by the end of this year there will be one or two successful candidates.

Nonetheless, Dr. Soumya Swaminathan also says that the anti-malarial drug hydroxychloroquine may have a role in preventing people from being exposed to Covid-19 infection. Clinical trials are underway in this regard.

It is not yet clear whether hydroxychloroquine has a role in preventing or reducing the severity of the Covid-19 epidemic early in the infection, he said.
Referring to other tests being done by the World Health Organization, he said that we do not know this yet. Therefore, there is a need to complete large scale trials and obtain data.
