    Vaccines are all biological substances produced from living things, administered to trigger the host’s body defense system to develop immunity against a specific pathogen from which they are produced.

Vaccines work by stimulating either humoral or cellmediated immunity or both to differentiate. Even though vaccination is the powerful and cost-effective weapon of disease prevention and control of infectious and diseases, there are factors those, hinder its effectiveness (constraints of vaccine effectiveness). These factors are technical constraints, pathogen-related constraints, vaccine related factors, host-related and environmental and management-related constraints... View more»
