New york, Dec 23: The U.S. began vaccinating the population against COVID-19 last week, but mass adoption is not a guarantee.
Nearly 4 in 10 Americans say they would “definitely” or “probably” not get a vaccine, according to a Pew Research Center survey of 12,648 U.S. adults from Nov. 18 to 29.
While this is better than Pew results from September, which showed that nearly 50% of respondents were leaning toward not getting the vaccine, it still falls short of what is needed to adequately protect the country. To achieve herd immunity, about 70% of the population needs to be vaccinated or have natural antibodies, experts say.
