People may need multiple doses of a potential vaccine to immunize against coronavirus. This was stated by one of the founders of the American corporation Microsoft, billionaire Bill Gates, who five years ago warned of the threat of a new virus pandemic.
вЂњNone of the vaccines at the moment looks like they will work with the introduction of a single dose. From the beginning, it was just hoped,вЂќ вЂ” said Bill Gates, reports CBS.
To defeat the coronavirus, he said, a global effort is needed to spread the vaccine around the world.
вЂњIf you want to be completely a barrier to (coronavirus) transmission, you need to reach 70-80% (of the population) globally. These are incredibly large numbers,вЂќ Gates said.
We will remind, Bill Gates in 2015 predicted that the greatest threat to humanity is viruses and the world is not ready to withstand new epidemics. This is partly due to the fact that countries spend huge amounts of money on the nuclear deterrent. At the same time, very little funds are allocated to prevent epidemics.
