Their track record has been that Jonas Salk’s lightning-fast development of polio vaccine in less than 4 years, and Ebola vaccine was approved in December 2019 after the first Ebola incidence was found in 1976, i.e. more than 40 years after.  From discovery to approved vaccination is a 10-year long process involving 2-5 years of discovery research, 2 years of pre-clinical period, 5 years of clinical development at its very best, 1-2 years of regulatory approval, and then of course comes in the manufacturer. The clinical development period has its 3 phases that is creating the buzz we hear day in and day out these days. Phase I is when researchers concentrate on the question, “Is it safe?” Phase II tries to establish whether the vaccine is activating an immune response or not. Then comes Phase III when they answer
