A vaccination is an important part of avoiding COVID-19. In an unusual attempt to combat the epidemic, experts from all over the world have collaborated to shorten a 10-year research and development timetable into around 10 months. Over 200 vaccinations are under development, with dozens more in clinical testing. The Food and Drug Administration has granted emergency use authorization to three vaccines in the United States (FDA). One of those three vaccines, the Pfizer-BioNTech vaccine, has acquired full FDA clearance.

To work at such a breakneck rate, researchers looked into novel vaccination platforms such as mRNA. Manufacturers developed batches of vaccinations without waiting for final clinical trial findings in order to make them ready as soon as possible if they were shown to be safe and effective.
