### WHO Reaffirms Vaccine Safety: No Link to Autism The World Health Organization (WHO) has recently conducted a comprehensive review reaffirming that vaccines do not cause autism, effectively countering persistent misinformation circulating online. This conclusion is supported by decades of research, including a thorough analysis of 31 studies conducted over 15 years. The WHO's findings are particularly significant in light of recent claims made by the U.S. Centers for Disease Control and Prevention (CDC), which have raised concerns among public health experts. WHO Director-General Tedros Adhanom Ghebreyesus emphasized the importance of vaccines in saving lives and maintaining public health, stating that the evidence overwhelmingly supports vaccine safety and efficacy. ### Breakdown of the WHO's Findings 1. **No Causal Link Established**: - The WHO's Global Advisory Committee on Vaccine Safety reviewed extensive evidence and found no causal link between vaccines and autism, including those containing thiomersal and aluminum adjuvants [https://24newshd.tv/12-Dec-2025/vaccines-cause-autism]. 2. **Historical Context**: - This is the fourth review conducted by the WHO on this topic, with previous assessments in 2002, 2004, and 2012 all reaching the same conclusion [https://www.healthandme.com/health-wellness/is-there-any-link-between-vaccines-and-autism-who-explains-why-not-article-153282845]. 3. **Response to Misinformation**: - The WHO's announcement comes in response to recent changes in the CDC's messaging, which some experts believe undermines established scientific consensus [https://www.thehawk.in/news/health/who-refutes-us-cdcs-claims-on-vaccines-and-autism-reaffirms-there-is-no-link]. 4. **Impact of Anti-Vaccine Rhetoric**: - Prominent figures, such as Robert F.
