If, by "winning," you mean that anti-vaxxers are gaining ground in their fight to bring back the diseases that used to kill and maim countless millions of children throughout history until researchers started developing vaccines to protect them, that is a "win" that very few people support.
*Most* parents want their children to grow up healthy. This is why the anti-vax movement has so few resources. Other than rich anti-humanists like that Kennedy kid (RFK?), there are few advocates for killing off children with deadly diseases.
No, by winning we mean that statists like you are being denied the right to supplant parental authority in medical decision making for children.
Just as the AAP relies on a fraudulent gun study (Kellerman) to justify their anti-gun position, the vaccine pushers have zero long-term, double blind studies on safety or efficacy to justify approval on the shots.
Anyone with the interest can look up deaths from diseases supposedly eradicated by vaccines, and see that 90-95% of the decrease in deaths had occurred prior to the introduction of the particular vaccination. That the vaccine pushers attribute those improvements to vaccination is a big indication of the deception in their position.
