This past spring the world locked down. Stores were closed, everyone was required to work from home, and masks became the latest fashion trend. This shift occurred because a virus, Covid-19, began making its way around the world. It has been about 4 months since our society locked down for the protection of its people and while it is slowly opening back up there are fears that without a vaccine or cure for Covid-19 it is going to keep spreading and we are going to have to remained locked down. Many pharmaceutical companies are working night and day to create a vaccine that can be widely distributed to help stop the spread of Covid-19. A drug that is for humans needs to be tested on humans to ensure it works before it can be approved and sold.
