AstraZeneca has signed pacts with several vaccine producers globally to ramp up production facilities to meet the demand. In a recent briefing, WHO head noted the progress made by several companies but said that it would be still unrealistic to expect a vaccine before 2021.

“We’re making good progress…Realistically it is going to be the first part of next year before we start seeing people getting vaccinated,”

However, a lot more study is needed before we consider this fact- how affordable the vaccine will be, will it reach all people and whether everyone will have fair access to it. These concerns have to be taken care of as well.
