Some people who already had COVID-19 are hesitant to get the vaccine, as many believe their natural antibodies are enough protection, but those who never tested positive for the virus are even more resistant to being inoculated.
A recent Axios-Ipsos poll found 25 percent of people who think they had COVID-19 but never tested positive aren't interested in being vaccinated. Without knowing if a person actually had COVID-19, there's no way for health officials to accurately calculate the level of herd immunity or how many people could be susceptible to the virus.
People who thought they had COVID-19 but weren't sure if they did were more likely to resist vaccinations than those who confirmed their infection with a test. Of those who tested positive for the virus, 15 percent of poll respondents said they weren't interested in the vaccine.
An estimated 65.5 percent of adult Americans have had at least one dose of the COVID-19 vaccine and President Joe Biden is likely to fall short of his goal of 70 percent of vaccinated individuals by July 4. At the current pace, about 66.3 percent of adult Americans are expected to have received at least one dose by Sunday, according to a Brown University tracker.
