Vaccine discovery report

How long does it take to prepare a vaccine?
 Statistics for the last 50 years:
 1.
 Zika virus
 First detected = 1946.
 Vaccine discovery = research.
 Duration = 63 years.
 2.
 Chickenpox
 First detected = 1953.
 Vaccine discovery = 1995.
 Duration = 42 years.
 3.
 Hepatitis B
 First detected = 1985.
 Vaccine discovery = 1971.
 Duration = 18 years.
 4.
 Ebola
 First detection = 197.
 Vaccine discovery = 2019.
 Duration = 43 years.
 5.
 AIDS
 First detected = 1971.
 Vaccine discovery = research.
 Duration = 39 years.
 .
 SARS virus
 First detected = 2003.
 Vaccine discovery = research canceled.
 Duration = 18 years.
 .
 Mars virus
 First identified = 2012.
 Vaccine discovery = research.
 Duration = 6 years.
 
 It usually takes 8 to 20 years to develop a vaccine.  There is no guarantee that he will be able to get a license even after that.  Scientists have not been able to discover vaccines for many diseases in 20, 30, 50, 60 years.  So don't run after the vaccine and focus on your work. Stay at home.
