Speak with your doctor – they will have a broader understanding of which vaccine suits you and your medical history. Want to understand and compare the world’s leading vaccines? Check out our Vaccine Comparison Chart.
Researchers around the world are creating and testing close to 100 vaccines in an effort to combat the novel coronavirus. The above chart breaks down leading vaccines which have shown promise through pre-clinical data, completed Phase 1/2/3 clinical trials, and have been authorized for emergency use.
Preclinical data is collected when testing a vaccine on cells and animals. If an immune response is detected, the study moves forward as a Phase 1 safety trial by testing the safety of the vaccine on a select number of people (typically around 20-80 people).
If the dosage is deemed safe and effective, the trial progresses to a Phase 2 expanded trial, in which hundreds of people receive the vaccine. At this stage, participants are split into groups to observe the vaccine’s efficacy and safety across a spectrum of ages.
A Phase 3 efficacy trial tests for vaccine efficacy against volunteers who receive a placebo. Thousands of participants are included in the trial, and an efficacy rate is determined for the vaccine against a virus.
Due to the nature of the coronavirus, some vaccine trials underwent combined phases (e.g. Phase 1/2) in order to accelerate development.
