Usually, vaccines are developed by small teams with limited budgets. But the COVID-19 vaccines were developed faster because:
- The SARS-CoV-2 virus that causes COVID-19 is related to a very common, well researched class of viruses known as coronaviruses.
- Scientists from around the globe shared their years of coronavirus research and worked together on the vaccine.
- Advanced technologies developed over the last 10 years were used in developing the vaccines.
- Governments and private companies provided nearly unlimited funding and put them at the front of the line for all paperwork and approvals.
According to the CDC, the approved vaccines meet the FDA’s rigorous standards established in June 2020.
