COVID-19 has now been around since late 2019 and came to the United States in early 2020. The virus has changed the course of many people’s lives. As of late February, 500,000 people in the U.S. had died.
Scientists have been working hard to develop a vaccine since the cases started. As the numbers increased so too did their efforts. Vaccines usually take years to develop. However, vaccines developed by Moderna and Pfizer have recently been approved for use after less than a year from the initial impact of the coronavirus.
