Strong vaccine supporter here, and I think studies like this are still worth doing. Healthy society has vocal skeptics that are occasionally correct. We also have authorities that are occasionally wrong. Scientists maintain trust in our most important systems by properly addressing claims through rigorous research rather than relying simply on authority. We’ve seen smoking and thalidomide (and I’m sure more relevant substances) scientifically ‘proven’ safe before causing massive harm. When anti-vaxx claims evolve (MMR, now aluminum), having solid population data helps counter misinformation with hard evidence. Active research helps us know which side the misinformation is actually on.
