Registration type criteria

BSI member

The BSI membership categories have recently expanded. If you’re a current BSI member, please make sure you’re on the right membership category before registering. If you have any questions, please email our membership team at membership@immunology.org.

Early Career/Clinician in training
An important change is the expansion of the Early Career Membership criteria to include anyone in the first seven years from receipt of their PhD. If you are currently a full member in your sixth or seventh year after completing your PhD, you might now be eligible for the Early Career Membership (past criteria for Early Career Membership: five years post PhD).

Complete criteria:

  • Scientists working in academia or industry or other professionals of a commercial organisation in their first 7 years from receipt of PhD or up to 10 years post first degree
  • Clinicians in training up to receipt of Certificate of Completion of Training (CCT) or permanent position
  • Professionals who have been working in a related field for less than 10 years post first degree
  • Nurse or allied healthcare professional first 3 years experience post qualification

Senior (Retired), Undergraduate and discounted memberships
We have introduced a new category for senior (retired). If you are currently retired from full time employment and have been a BSI member for a minimum of 15 years, you will be eligible for free membership. We also offer discounted membership fees for different groups. Any member who is on a career break for at least six months and Full Members who earn less than £25,000 per annum can apply for a 60% discount on their membership fees. Members living in countries defined as a low-income economy by the World Bank and those with UK refugee status may be eligible to claim free membership.
