Three-quarters of Americans would take a coronavirus vaccine after receiving certain assurances that it was safe, and another 9 percent would take one as soon as it was available, a Reuters/Ipsos poll released on Tuesday showed.

People wait in line to receive free face masks at the Prospect Park in the Brooklyn borough of New York, the United States, May 3, 2020. New York City (NYC) will be distributing over 100,000 face coverings in parks across the city free of charge from May 2 to 5. According to the guidance from the NYC Health Department, all New Yorkers are required to wear a mask or face covering in public and in situations where a 6-foot distance from others cannot be maintained.

 The strong support for a vaccine comes as vocal anti-vaccination protesters joined right-leaning groups to protest shelter-at-home orders imposed by public health officials in the wake of the coronavirus pandemic in the United States.

Development of a safe and effective vaccine is widely believed by public health officials to be key to controlling future outbreaks, but it is not clear how long that process would take - or if a vaccine can even be developed for the virus.

Asked to choose one or more reasons they would feel comfortable taking a new vaccine, about 40 percent of American adults surveyed in the Reuters/Ipsos study said they would wait until the US Food and Drug Administration approved such a vaccine, and 38 percent said they would try one after extensive, peer-reviewed clinical trials.

About 38 percent said they would wait until such a vaccine had already been taken by much of the public and proven safe. A smaller number, about 6 percent, said they would take a coronavirus vaccine after a friend or family member tried it, and the same number said they would try it if President Donald Trump were to endorse it.

Among those who were willing to be vaccinated against the virus, 89 percent would do so if it was made in the United States, and 11 percent said they would take it if it were developed in another country.

"A vaccine would be an important tool, because I don't think the virus is going to disappear," said Arthur Reingold, head of epidemiology and biostatistics at the University of California, Berkeley's School of Public Health. But he cautioned that people's willingness to take a vaccine will vary depending on what happens as time progresses.

"If there is a raging epidemic going on and bodies are piling up all over the place they're probably going to be more likely to get the vaccine," he said.

The highly contagious coronavirus has infected more than 1.2 million people in the United States, including at least 70,000 who have died from COVID-19, the respiratory illness it causes, according to a Reuters tally.

The Reuters/Ipsos poll was conducted online, in English, throughout the United States.
