For years, Democratic presidential candidate hopeful Robert F. Kennedy Jr. has raised serious questions about the safety of certain vaccine ingredients, an issue once the domain of small groups of parents that became a national issue with the onset of COVID-19.

During the pandemic, Mr. Kennedy also spoke out against the COVID-19 vaccines, personally and through supporting the Children’s Health Defense, where he served as chairman and chief legal counsel before stepping aside to focus on his campaign in April.
