Generally in this phase vaccines are tested in young healthy adult volunteers.
Stages of vaccine development. Our work to research develop and introduce a new vaccine typically goes through several stages. Vaccine development is characterised by a high failure rate often 93 between animal studies and registration of a product The discovery and research phase is normally two-to-five years according to the Wellcome Trust. If the vaccine triggers an immune response it is then tested in human clinical trials in three phases.
Wiku said on Thursday that vaccine development started with basic research also known as the exploratory phase. Planning and investment. Companies first make small batches and do small scale studies to characterise and optimise the production process.
In this somewhat simplified view vaccine research begins only after a. Candidate vaccines from the exploratory stage used on animal subjects to assess response. The 5 stages of vaccine development include exploratory preclinical clinical development approval and pharmacovigilance.
The transition to Phase II relies on the immunogenic and toxicity results from Phase I in a small cohort of healthy volunteers.
