The Syndicat Liberté Santé (SLS), a union formed in response to increasing restrictions on healthcare professionals, has announced its intention to file a legal complaint with the Council of State. The union is challenging what it describes as an overreach of authority and a suspension of a recommendation issued by the High Authority for Health on July 9, 2026, which was made public on July 20. The recommendation calls for a gradual implementation of an annual flu vaccination requirement for healthcare and social care professionals, starting with staff in nursing homes (EHPAD) and long-term care facilities, and eventually extending to independent professionals and students in health-related fields. The proposed vaccination mandate has sparked debate among various healthcare unions. While the SLS supports the legal challenge, not all unions agree with the approach. Some liberal and hospital-based unions have not endorsed the lawsuit, indicating a division in the healthcare sector over how best to address vaccination rates among professionals. The High Authority for Health has cited a significant gap in vaccination coverage among caregivers, which has prompted the recommendation for a more structured approach to ensure protection for both patients and staff. Jérôme Marty, president of the UFML-S (Union française pour une médecine libre), expressed support for a policy that would require all healthcare workers, including those in the ASH (Assistants de Santé) category, to attend vaccination discussions. He also proposed that the minister collaborate with the Medical Council, the High Authority for Health, and other relevant bodies to co-sign a unified statement on vaccination, which would be signed by all involved parties. Marty emphasized the importance of addressing the vaccination deficit among caregivers in a coordinated and inclusive manner. Rachel Bocher, president of the INPH (Intersyndical Nationale des Praticiens d'exercice Hospitalier et Hospitalo-Universitaire), supported the principle of vaccination, stating that healthcare professionals have a duty to protect their patients. Her comments reflect a broader perspective among some union leaders who see vaccination as a necessary measure to ensure the safety of both healthcare workers and those under their care. The debate over mandatory vaccinations continues to evolve, with differing views on the best way to implement such policies while respecting professional autonomy and public health needs.
