Recent surges of the Delta variant in much of the United States are attributable part to vaccine hesitancy.

According to a recent survey conducted by the U.S. Census Bureau, 26,760,000 Americans — or 10.7% of the 18 and older population — say they will either probably or definitely not agree to receive the vaccination when given the opportunity.

The share of eligible residents who will likely refuse vaccination varies considerably nationwide, from as many as 25.7% of the adult population to as little as 3.2%, depending on the state. States where the largest shares of adults are open to taking the vaccine are concentrated in the Northeast, while states in the West are home to the largest shares of adults reluctant to get vaccinated.

The majority of Americans who have yet to be vaccinated cite one of three reasons: either they are concerned about possible side effects, or they want to wait to see if it is safe, or they think that others would benefit more than themselves from a vaccination. Others cite different reasons.

Nationwide, 16,360,000 people, 6.6% of the adult population, do not trust the COVID-19 vaccines, and 4,620,000, or 1.9%, do not trust vaccines in general. Additionally, 12,020,000 American adults, or 4.8% of the 18 and older population, have not been vaccinated because they do not trust the government.

Meanwhile, the virus continues to spread. Since the beginning of the pandemic, there have been 33,451,965 confirmed cases of the virus and a total of 601,231 Americans have died as a result.

So far, 158,954,417 Americans — or 48.6% of the total population — have received the full course of vaccinations necessary to protect against COVID-19.
