Which clinical trial phase checks the safety and dose ranges which has to be completed within 1-3 years? Correct Answer Phase II
Clinical development of vaccine is one of the most important parameters in order to license vaccine. After being tested in animals, vaccines are found to be safe to be tested in humans. To license vaccine, three phases of clinical testing is required: Phase I checks the safety and immunogenicity trials take place which needs to be completed under 1 year. However, in phase 2 the same process is carried out along with checking dose range but this takes almost 1-3 years.
