24 – 25 March | Next blood donation campaign | Building 29

2025 was a record year for blood donation at CERN, with three campaigns including one spanning two days. These saw a 25% increase in the number of donors and 36% in the number of donations and we warmly thank all donors for their support.

According to the Geneva blood barometer, blood stocks in the region remain low: CERN's support as a key contributor (ranking 2nd as the region's biggest blood donor after the Hôpitaux universitaires de Genève (HUG)) is essential to ensuring availability of blood stocks for those in need, when they need it most. Furthermore, as of 1 February 2026, the criteria for blood donation have changed and certain previous restrictions lifted, meaning that a wider population can donate. In particular, regarding stays in the United Kingdom between 1980 and 1996, the permanent exclusion is lifted and the individuals concerned can once again donate blood, The HUG explain more in this article (in French).

CERN will hold a its first blood donation session of 2026 over two days, on Tuesday 24 and Wednesday 25 March, from 8.30 a.m. to 4.30 p.m. in collaboration with the HUG in Building 29.
