Pfizer the Saviour

<p>Yesterday, drugmaker Pfizer <a href="https://www.nytimes.com/2020/11/09/health/covid-vaccine-pfizer.html">announced</a> that early analysis of its coronavirus vaccine trial suggested the vaccine (developed in conjunction with BioNTech) was robustly effective in preventing Covid-19. And while multiple pharma companies have released details about their own vaccines so far, there is a lot of optimism surrounding Pfizer’s announcement.</p> <p>So why are people this excited you ask?</p>
