69-year-old Robert Kennedy Jr. today announced his candidacy for the Democratic nomination in the 2024 presidential election, intending to stand in the way of the current US president’s ambition Joe Biden to seek re-election to the White House.

The 80-year-old Biden had said last Friday that he intends to run for a second presidential term and that he is going to officially announce it “relatively soon”.

Descendant of the well-known political dynasty, the Robert Kennedy the younger is considered an outsider in the race by most political analysts, who believe he could use his candidacy to promote claims that childhood vaccinations pose health risks — a theory that has been discredited by many scientific studies.

At a rally in Boston, however, Kennedy did not address the anti-vaccination movement or question the effectiveness of vaccines. He emphasized that he intends to prioritize scientific research to combat chronic diseases if he is elected president of the United States.

A leading figure in the anti-vaccine movement, Robert Kennedy has been banned from social media platforms YouTube and Instagram for spreading misinformation about vaccines for Covid-19.

He is the nephew of former US President John F. Kennedy, who was assassinated in 1963, and the son of former Senator Robert F. Kennedy, who was assassinated in 1968 during the primary election. He did not fail to mention his father and uncle, but noted that some of his family environment do not support his candidacy.

Political analysts point out that he has supporters among Republican voters because of his anti-vaccine action. In 2017, then-U.S. Pres Donald Trump had suggested that he join a vaccine evaluation committee, provoking a strong reaction from the scientific community.

During the Covid-19 pandemic, Kennedy criticized social distancing measures and mandatory vaccination. In January 2022, he argued at a rally in Washington that during the pandemic Americans had fewer freedoms compared to Jews living in Nazi Germany. He later apologized for that comment.
