Plus, the virus has been spreading rapidly, so regulators could see if vaccine candidates made a difference in a shorter amount of time. People enrolled quickly due to widespread public interest. Large scale vaccine clinical trials were organized quickly using networks established in the pursuit of an HIV vaccine. Participants enrolled in the trials quickly The spike protein’s genetic code was plugged into preexisting technology with an already working process that had been evaluated for other vaccine uses, such as in the fight against dengue. After SARS-CoV-2 was sequenced, it took just a few days to make the mRNA vaccine candidates. Researchers have been developing and researching an mRNA vaccine platform for over 10 years. They already knew that the spike protein could be targeted by a vaccine, which gave them a goal to work toward immediately. Scientists had studied other coronaviruses for 50 years. In this case, SARS-CoV-2 was a new virus, but it belongs to a family of viruses with similar traits. Researchers need to do a lot of academic research and pre-clinical work to make medical products such as vaccines. ![]() Rather, a true global emergency paired with early application of substantial resources made it possible. How did the vaccines get developed so quickly? The vaccine developers did not cut corners. The CDC continues to closely monitor these vaccines for safety and efficacy. Despite the fast timeline, these vaccines went through the appropriate clinical trials, just like other vaccines before. In a first for vaccine development, two COVID-19 vaccines were created, evaluated and authorized for emergency use in under a year.
