 Skepticism of vaccines in the U.S. could be a problem in the fight against the coronavirus pandemic. Political science researchers Matt Mota and Kristin Lunds Trujillo conduct a survey of almost 500 adults in the U.S. in April on their views on vaccines for COVID-19. 23% of the 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 COVID-19 vaccine and collective immunity. Experts estimate that 50 to 70% of Americans would need to develop immunity to COVID-19 naturally or through a vaccine. For comparison, just 37% of Americans chose to get the flu vaccine in 2017 to 2018.
