As the global pandemic continues, trials have been established to test whether existing drugs such as hydroxychloroquine could be repurposed to treat patients with COVID-19. There are also hopes that a novel drug will surface. But questions remain about when treatments and vaccines will become available.
There is currently great optimism that a treatment or vaccine will be developed quickly, but there is no assurance that such a vaccine or treatment will be highly effective or that normalcy will return in any particular timeframe. A recent study published in the Lancet ID by Jonathan J. Darrow, Mehdi Najafzadeh, Kristina Stefanini, and Aaron S. Kesselheim provides data that might help to temper enthusiasm with evidence.
