How Much Do You Know About Covid-19 Vaccines?

Life-saving shots are coming to end the pandemic. Take our quiz to find out how prepared you are.

By John Lauerman and Thomas Mulier

Covid-19 vaccines have arrived and are spreading out across the world, with more than 128 million administered globally as of Feb. 6, according to Bloomberg’s vaccine tracker. The shots already come in a variety of types, and there are more in different stages of testing from manufacturers and laboratories all over the world. Now it’s time to test your Covid-19 vaccine IQ. How much do you know about how they were made, where they come from, who’s actually received them, and who hasn’t? Some of the answers may surprise you. One thing that there’s little question about: while some side effects have been observed, the vaccines are overall safe and highly effective. If you’re eligible to be vaccinated, you should step up for your own protection, and to help save lives in your community. On to the quiz.
