Covid-19 vaccine acceptance across the world increased by about 4 per cent between 2020 and 2021, according to a new study whose findings could help improve the coverage of future immunisation drives.
The research, published last week in the journal Nature Communications, studied Covid-19 vaccine hesitancy globally in June 2021 in over 23,000 individuals across 23 countries.
Researchers, including those from City University of New York in the US, found that more than three-quarters of respondents reported vaccine acceptance, up from 71.5 per cent the previous year.
