The World Health Organization (WHO) predicts the first use of the coronavirus infection-19 vaccine will be available early next year.

"The researchers are making great progress in the development of the Corona 19 vaccine," said Michael Ryan, WHO Deputy Secretary for Emergency Response, Reuters reported in a Q&A on 22nd local time.

Ryan says several vaccines are in Phase III clinical trials, and so far have not failed in both safety and ability to generate an immune response.

In the meantime, WHO says it is working to expand production capacity and make it accessible to everyone when vaccines are developed.

He added that caution should be taken to attend school until it can control the local infection of Corona 19.
