Despite the loudest social media and government officials' voices, an overwhelming majority of the sample of over 4,500 Americans say the MMR and other vaccines are safe. Additionally, RFK Jr. is underwater with an approval/disapproval of 37-52. Some issues, such as discouraging unhealthy eating, get bipartisan support (approx 70% approval by both Dems and Reps).
There is room to improve upon public health, especially with 16% of Americans not thinking vaccines are safe, the large measles outbreak in South Carolina, and Casey Means refusing to outright recommend MMR vaccination.
