Saudi Arabia has made the meningitis vaccine mandatory for all Hajj pilgrims in 2025 to protect public health and prevent disease outbreaks. This requirement applies to both Saudi residents and international visitors. Pilgrims must provide proof of vaccination to register or book Hajj packages. The policy aims to ensure a safe pilgrimage, as Hajj gathers millions of people, increasing the risk of infections. The General Authority of Civil Aviation (GACA) also requires pilgrims to carry health documents, including vaccination certificates, which will be checked during registration and upon arrival. These steps are part of Saudi Arabia’s commitment to maintaining health and safety during Hajj.
