New vaccine is being tested on people to assess if it is safe and efficacious. In this stage, vaccine candidates are tested for their safety and efficacy. Further, clinical trials are NOT vaccination programs.

Unapproved vaccine is authorized for limited use as it is deemed safe and efficacious based on review of interim data of Phase III clinical trials.

New and approved vaccine is proven safe and efficacious based on review of complete data from Phase III clinical trials and can therefore be purchased and used for vaccination programs.
