evidence: It’s not just the COVID vaccines; it’s every single one of them"; "The fully unvaccinated kids are always healthier"; "vaccines are causing chronic disease in America" [...] One example is this video in which entrepreneur Steve Kirsch—who has repeatedly made false claims about vaccines—claimed that vaccines harm children and "are causing chronic disease in America", and that "The fully unvaccinated kids are always healthier". He added, "It’s not just the COVID vaccines; it’s every single one of them". [...] Kirsch’s claim that vaccination leads to chronic diseases is also unsubstantiated and contradicted by scientific evidence, as Health Feedback explained in earlier reviews. Robust studies found no association between vaccines or their ingredients with poorer health or with conditions such as asthma, infections, autoimmune diseases, cognitive delay, autism spectrum disorder, and attention deficit/hyperactive disorder, among others[6-12].
