Around 1.3 billion people worldwide said that they will not get a COVID-19 vaccine if it became available at no cost, according to a Gallup poll taken in the last six months of 2020 and released Monday.
The 1.3 billion was a combination of 29 percent, or around three in 10 adults, worldwide who refused to be vaccinated, and another 3 percent who were undecided or refused to answer.
