Is the world ready for a COVID-19 vaccine? At the beginning of November, Pfizer and BioNTech announced that their vaccine candidate was more than 90% effective at preventing COVID-19 infection. Since then, other good news has followed, with collaborations, including Moderna and AstraZeneca, publishing similarly positive results. This is a phenomenal feat that would have been unimaginable just one year ago. But a vaccine is only as effective as its deployment and uptake.
