Maybe you should qualify 'anti-vaccine claims'. Throughout the history of vaccines which have saved countless lives, some people have died or suffered severe reactions linked to a vaccine. This is hardly surprising given our metabolic heterogeneity.

'Anti-vaccine claims' suggests a taking of sides on that knee-jerk division into those who claim without evidence that almost or even all vaccines are deadly and on the other hand, those who are frankly contemptuous of any claim that a particular vaccine (evident particularly with the vaccines developed in response to the Covid outbreak) might be dangerous for certain people. Both extreme views have been on view recently and are indefensible.

The major issue here is the difficult task of identifying people likely to react badly to any specific vaccine.

Meanwhile 'Congress and Institute of Medicine Confirm Government Licensed and Recommended Vaccines Can Cause Injury and Death' and 'The 1986 National Childhood Vaccine Act was the first U.S. law to officially acknowledge that childhood vaccines licensed and recommended by the federal government, which are routinely mandated for school attendance by state governments, can and do injure and kill a minority of children.'
