Vaccine development
Vaccines undergo years of testing to ensure maximum efficiency and safety.
The process usually takes between 10-15 years from start to finish, and is broken up into phases including
- Exploratory
- Pre-clinical
- Clinical development
- Regulatory review and approval
- Manufacturing
- Quality control
Vaccines are tested in closely monitored trials on thousands of people before they are licensed and used regularly in a clinical setting. In the ongoing COVID-19 trials the timeline is being sped up to meet the urgent need for a vaccine, although the same process of rigorous testing is underway.
