Though more than 131 million Americans have received at least one dose of COVID-19 vaccine to date, public confusion and uncertainty about the importance of second doses and continued public health precautions threaten to delay a U.S. return to normalcy, according to Cornell-led research published April 28 in the New England Journal of Medicine.
Though more than 131 million Americans have received at least one dose of COVID-19 vaccine to date, public confusion and uncertainty about the importance of second doses and continued public health precautions threaten to delay a U.S. return to normalcy, according to Cornell-led research published April 28 in the New England Journal of Medicine.
In a nationally representative survey of more than 1,000 American adults conducted in February, less than half of respondents said they believed the Moderna and Pfizer-BioNTech vaccines provided strong protection against COVID-19 a week or two after a second dose, consistent with guidance from the U.S. Centers for Diseases Control and Prevention (CDC), the researchers found. One-fifth believed the vaccines provided strong protection after only one dose, and another 36% were unsure.
Among vaccinated survey respondents (19% of the sample), barely half reported being told about the timing of vaccine protection, and only slim majorities said they’d been advised to continue wearing masks, social distancing and avoiding crowds.
“Many Americans, including many of those who have already received a first vaccine dose, remain confused about the timing of protection and the necessity of a second dose,” the researchers concluded. “Moreover, a large proportion of vaccinees report being uninformed about CDC guidance regarding the need to continue to take prophylactic measures.”
