Adar Poonawalla, the CEO of the world’s largest vaccine manufacturer has estimated that the world will need around 15 billion doses of the Covid-19 shot if it is a two-dose vaccine, as is the case with measles or rotavirus. He has warned the world over the shortage of COVID-19 vaccine shots and said it will take at least four to five years to immunise the world against deadly COVID-19 infection.

In an interview with Financial Times, Poonawalla said "It’s going to take four to five years until everyone gets the vaccine on this planet."

He went on to say that the commitment far exceeded the capacity of other vaccine producers. "I know the world wants to be optimistic about it .... [but] I have not heard of anyone coming even close to that [level] right now," Poonawalla told the publication.
