COVID-19 needs a big science approach

There is an unprecedented race to develop a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). With at least 44 vaccines in early-stage development, what outcome can we expect? Will the first vaccine to cross the finish line be the safest and most effective? Or will it be the most well-funded vaccines that first become available, or perhaps those using vaccine technologies with the fewest regulatory hurdles? The answer could be a vaccine that ticks all these boxes. If we want to maximize the chances for success, however, and have enough doses to end the coronavirus disease 2019 (COVID-19) pandemic, current piecemeal efforts won't be enough. If ever there was a case for a coordinated global vaccine development effort using a “big science” approach, it is now.
