Kevin Sneader, Global Managing Partner of McKinsey, looks at the challenges around a COVID-19 vaccine from the corporate business leadership perspective on Business In 60 Seconds.

What will it take to bring a COVID-19 vaccine to market?

Now, there are reasons to believe that a COVID-19 vaccine can indeed be developed faster than any other in history. For a start, the characteristics of this virus, unlike some families of viruses, coronaviruses overall have been shown to mutate at relatively low to moderate rates. Moreover, the sheer number of development efforts mean that over 275 vaccine candidates in development, with over 45 already in clinical trials. This is coupled with unprecedented access to funding, given over $17 billion has been committed to vaccine development and supply. That said, there are multiple hurdles to overcome. They start with getting the science right, including validating the platform technologies and demonstrating both safety and efficacy. But let's not forget that we also need enough capacity to manufacture and supply in place to reach patient populations now, and over time. And last, but by no means least, people need to be willing to be vaccinated. In the US in May, 72% of Americans said they would get vaccinated. That number has fallen to 51% in September.
