It’s become pretty clear that unless some sort of miracle takes place, we aren’t going to really dig ourselves out of the coronavirus pandemic without a vaccine.
Fortunately, researchers have been hustling to design, test and eventually mass-produce a vaccine that’ll bring us some immunity against COVID-19. Initial evidence on the safety and effectiveness of some of the potential vaccines is promising. As Dr. Anthony Fauci, director of the National Institute for Allergy and Infectious Diseases, said, it’s something to be “cautiously optimistic” about.

To carry out those trials, researchers need tons of volunteers — people of all ages, genders, ethnicities and backgrounds — to ensure that the final vaccines work across the general population.

Each vaccine has to be studied in
