"Vaccination is a priority over other economic policies, which must be taken by the states this year" International Monetary Fund leader Kristalina Georgieva argued Wednesday during CNBC's Global Summit.

For Kristalina Georgieva this measure may even "be more important than any fiscal or monetary policy. "Vaccination in all countries is a prerequisite for global economic growth and this has not been done yet. Vaccination is running at two speeds across the globe," she warned.

"This is the best investment of our lives," exclaimed the leader of the international financial institution.

The IMF has already called for at least 40% of the global population to be vaccinated by the end of the year, and for at least 60% of the entire planet to be immune by June 2022.

Last month, the organization even suggested that more than 40 billion Euros be invested in global vaccination, and assured that if this happened, the world economy would receive a return of more than 8 trillion Euros.

The IMF has predicted global GDP growth of 6% this year and 4.4% next year. However, the institution has already pointed out that the realization of these figures will depend, "in large part, on the evolution of vaccination programs, particularly in developing countries."
