Currently, there is limited information on the field of immunosafety and the importance of immunosafety in evaluating the relative safety of new drugs, therapies, and environmental agents that affect the immune system and determine risk to human health contained in one resource. There are an increasing number of therapies, drugs, environmental agents, and infectious agents (e.g. coronavirus) that affect the immune system either directly or indirectly and these effects are increasingly complex. Since both scientists and the public are increasingly becoming aware of the importance and involvement of the immune system (particularly in drug and vaccine development), this website intends to provide information on the numerous aspects involved in immunosafety evaluation. The intent is to share and disseminate information on immunosafety considerations to the scientific community and also to provide a resource for the public that is keenly interested in the process and the (lengthy) timelines of how therapies and vaccines are made available.
