It is the same mindset: certain historical mishaps (which existed for vaccines too) when the technology was in its infancy justifying a complete rejection of its benefits even though said benefits would overwhelmingly win in any cost-benefit analysis. But this mindset is fueled by an underlying deeper fear of progress, a fear which only searches for excuses but it exists even without them, like in the case of anti-GMO fears, another dear cause of the "green" activists.
