Coronavirus vaccines speed ahead, but experts fear not everyone will take them

If scientists build it, will people take it? It’s a question drugmakers should be asking as they race to deliver a vaccine for the new coronavirus.

As few as half of Americans say they will get vaccinated, according to recent polling, well short of the 70% to 90% needed to achieve the ‘herd immunity’ that can prevent the spread of the SARS-CoV-2 virus. While convincing vaccine opponents might not be possible, public health officials, governments and drugmakers need to be thinking about reaching those who may hesitate to get a vaccine or doubt its effectiveness.
