Vaccines and COVID-19: The latest hopeful research

What is the latest in COVID-19 vaccine advances? Can currently authorized vaccines protect against newly emerging SARS-CoV-2 variants? In this Hope Behind the Headlines feature, we examine these and other questions.

New, and possibly more contagious, variants of SARS-CoV-2 — which is the virus that causes COVID-19 — are emerging in countries around the world. Add to that the fact that the global number of COVID-19 cases is currently at over 95 million, and it can be difficult to remain optimistic that we will see the end of the pandemic anytime soon.
