Covid19 vaccine tracker: when is a coronavirus vaccine actually coming?
Over 170 groups of researchers are rushing to create a safe and effective vaccine. This is their advancement
Researchers across the globe are rushing to create a vaccine against Covid-19, with over 170 candidate studies currently monitored by the World Health Organization (WHO).
Vaccines normally require years of testing and extra time to create scale, but scientists want to produce a coronavirus vaccine in 12 to 18 weeks. They need to follow higher security standards than other medications since they're given to a large number of healthy men and women.
How are offenses examined?
At the pre-clinical phase of analyzing, researchers give the vaccine to animals to find out whether it activates an immune reaction.
In stage 1 of clinical testing, the vaccine is given to a small number of individuals to find out whether it's secure and to find out more about the immune response it provokes.
In stage two, the vaccine is given to countless individuals so scientists can find out more about its security and proper dosage.
In stage 3, the vaccine is given to tens of thousands of people to verify its security -- such as infrequent side effects -- and effectiveness. These trials require a control group that's given a placebo.
