Student Vaccination Policy

Immunization against life-threatening diseases is an important tool in the prevention and mitigation of infectious disease outbreaks. This vaccine policy may be modified in response to changes in public health requirements or recommendations. To protect the health of both students and the community as a whole, Caltech has required the following vaccines (or serologic proof indicating immunity, when applicable) for all enrolled students:

• Varicella (Chicken Pox): Two doses of varicella (chicken pox) vaccine OR blood test showing immunity (positive titer).
• Tetanus, Diphtheria, and Pertussis (Tdap): One dose of tetanus, diphtheria, and pertussis (Tdap) given after age 7. Afterward, a booster dose of tetanus and diphtheria (Td) every ten years.
• Meningococcal Conjugate ACWY (Meningitis): One dose of meningococcal conjugate ACWY (meningitis) after age 16 for all students under age 22.
