1.All the medicine and every vaccine must to go through extensive and a rigorous testing to ensure it is safe before it can be introduced in a country
2. Experimentally vaccine is first tested in animals to evaluate it's safety and potentially to prevent the disease after that tested in human clinical trials, in three phases
3.In phase 1 the vaccine is give small number of volunteer to assess safety and immune response and determine right dose
4.In phase 2 the vaccine given hundred of volunteers those people closely monitor for any side effect and immune response,in this phase some volunteers receive the vaccine and other do not, which allow comparison to be made and conclusion drawn about the vaccine, in theses phase data also collected whenever possible on disease outcome
5.In phase 3 the vaccine is given 1000 of volunteers, some of receive investigational vaccine and some of whome do not just like in phase II trials, after that collected data from both group to assess the vaccine is safe and effective against the particular disease
once the result of clinical trial available review of efficacy safety and manufacturing for regulatory and the public health policy approvals, before vaccine introduced into national immunization program
