Skepticism of vaccines in the U.S.
could be a problem in the fight
against the coronavirus pandemic.
Political science researchers Matt Motta
and Kristin Lunz Trujillo conducted a survey
of almost 500 adults in the U.S. in April
on their views on vaccines for COVID-19.
23% of respondents said they would not
be willing to get vaccinated if a
 covid-19 vaccine becomes available.
62% of the people who were already skeptical
about vaccines were not willing to change their mind.
These preliminary findings suggest that 
anti-vaccine beliefs could jeopardize the effectiveness
of a COVID-19 vaccine and collective immunity.
Experts estimate that 50-70% of Americans
would need to develop immunity
to covid-19- naturally or through vaccine.
For comparison,
 just 37% of American adults chose to get the flu vaccine
in 2017-18.
