Disease has plagued humanity ever since it first walked upon this Earth; they have ravaged entire nations, wiping out unbelievably large numbers of people. They still wreak havoc to this day, for mankind is amidst a pandemic. But the reason why we still stand here today able to go around in our everyday lives and do the things that we love the most, while being almost unaffected by not only COVID-19, but also many other terrible, despicable illnesses, is because of vaccines. This i2 project will focus on how vaccines came to be, work, and are made. It will also go over mRNA vaccines, the differences between it and traditional immunizers, and how it enabled the COVID-19 vaccine to be developed in an astonishing 11 months, obliterating any previous record.
