While the majority of Democratic voters support COVID-19 vaccinations, the rise of Robert F. Kennedy Jr., a self-described anti-vaxxer, as a Democratic presidential candidate in 2024 has brought attention to the existence of anti-vaccine sentiment among some liberals and progressives in the United States. Kennedy, a descendant of one of the country's most prominent political families, has a built-in platform that allows him to reach millions, which could potentially amplify his anti-vaccine message. Additionally, Democratic politicians' expressions of concern about the Trump administration's handling of the COVID-19 vaccine rollout may have inadvertently bolstered anti-vax groups. In 2019, Democratic presidential candidate Tim Ryan also came under scrutiny for praising a vaccine skeptic in his book, despite asserting that he is pro-vaccine and has vaccinated himself and his children.

Robert F. Kennedy Jr. is an anti-vaccine activist and 2024 Democratic presidential candidate
Robert F. Kennedy Jr., a descendant of one of the US's most prominent political families, is an anti-vaccine activist and 2024 Democratic presidential candidate. He is a lawyer, author, conspiracy theorist, and anti-vaccine activist. Kennedy has promoted vaccine misinformation and conspiracy theories, including the scientifically disproven claim that vaccines cause autism. He has also been associated with COVID-19 vaccine misinformation and has appeared at events pushing far-right conspiracy theories.
Kennedy has a long record of promoting anti-vaccine views and is considered one of the world's most influential spreaders of fear and distrust around vaccines. He has published many articles and books on the topic of vaccines, including "Thimerosal: Let the Science Speak: The Evidence Supporting the Immediate Removal of Mercury – a Known Neurotoxin – from Vaccines." In this book, he claims that thimerosal, a preservative used in some vaccines, is a neurotoxin, despite the CDC stating there is "no convincing evidence of harm caused by the low doses of thimerosal in vaccines."
Kennedy has also played a role in spreading misinformation during one of the worst measles outbreaks in recent memory. In 2018, two infants in Samoa died when nurses accidentally prepared the MMR vaccine with expired muscle relaxant rather than water. Kennedy and his nonprofit group, Children's Health Defense, spread misinformation in the area, causing the vaccination rate to drop to dangerously low levels.
Kennedy has insisted that he is not anti-vaccine, saying he only wants vaccines to be rigorously tested. However, he has shown opposition to a wide range of immunizations and has made numerous false and misleading claims about vaccines, autism, and COVID-19. In a 2023 podcast interview, he stated, "There's no vaccine that is safe and effective." Kennedy's personal Twitter account was also found to be the top "superspreader" of vaccine misinformation on the platform, responsible for 13% of all reshares of misinformation.
Robert F. Kennedy Jr.'s anti-vaccine activism and spread of misinformation have drawn significant criticism, with some accusing him of fueling vaccine hesitancy and endangering public health. Despite this, he continues to be a prominent voice in the anti-vaccine movement and is now seeking the Democratic nomination for president in 2024.

Tim Ryan, a 2020 Democratic presidential candidate, praised vaccine skeptic Vani Hari
In 2019, it was reported that Tim Ryan, a Democratic presidential candidate for the 2020 election, had praised vaccine skeptic Vani Hari in his 2014 book, The Real Food Revolution: Healthy Eating, Green Groceries, and the Return of the American Family Farm. Ryan, an Ohio House representative, has regularly promoted wellness and has a particular interest in mindfulness and nutrition. In his book, he commended Hari's work, calling her a "one-woman consumer protection agency".
Hari, a wellness blogger and self-proclaimed wellness activist, is known by the moniker "Food Babe". She has amassed a wide online following and has promoted healthy eating. On her website, she touts her "Food Babe Army Accomplishments", listing fast-food restaurants and large food companies that were pressured to disclose their ingredients and remove certain chemicals from their products. She has also been critical of vaccines. In 2015, she wrote, "I want you to think about what you are directly injecting into your bloodstream before you consider jumping off the ledge with other lemmings and taking this year's Flu Shot". The Centers for Disease Control and Prevention (CDC) has stated that "there has been extensive research supporting the safety of flu vaccines".
Ryan also praised Mark Hyman, a doctor at the Cleveland Clinic, in his book. Hyman wrote an essay in 2010 warning about the impact of vaccines on a healthy child. Ryan wrote that Hyman "has given every American a clear and straightforward field manual on how to get and stay healthy, for themselves and for our country".
In response to the controversy, a spokesperson for Ryan said that the congressman was “a long-time supporter of mandatory vaccinations”, and that Ryan and his wife, Andrea, have vaccinated their own children. They added, "just because [Hari and Hyman] were referenced in Ryan’s book on healthy food does not mean he endorses every stance they have taken in the past or will take in the future”.

Joe Biden and Kamala Harris expressed distrust in Donald Trump's handling of the COVID-19 vaccine
During the 2020 presidential campaign, Joe Biden and Kamala Harris expressed distrust in Donald Trump's handling of the COVID-19 vaccine. While they were not anti-vaccine, they raised concerns about the former president's rushed rollout and the risk of political influence over vaccine development. In a September 2020 interview, Harris stated that she would not trust Trump's word on the vaccine's reliability and efficacy. Biden echoed similar sentiments, questioning the administration's inconsistent approach and its impact on public confidence.
Video clips on social media have been shared out of context, suggesting that Biden and Harris doubted the COVID-19 vaccines themselves. However, their statements were directed at Trump's trustworthiness and ability to ensure a safe and transparent vaccine process. The concerns raised by Biden and Harris contributed to a broader trend of vaccine skepticism among Democrats and Republicans alike.
The context behind Biden and Harris' statements is crucial. As the pandemic unfolded, Trump pushed for a rapid vaccine rollout, even speculating that vaccines could arrive before the 2020 Election Day. This ambitious timeline clashed with the more cautious approach advocated by scientists and drug makers, who emphasized safety and effectiveness over speed. Biden and Harris, along with other Democratic politicians, voiced worries that the Trump administration might be rushing the vaccine development and approval process.
The skepticism expressed by prominent Democratic figures had unintended consequences. By highlighting issues with the vaccine development process, they may have inadvertently bolstered anti-vax sentiments among the public. This dynamic was observed by Robert F. Kennedy Jr., a prominent anti-vaccine activist and descendant of a prominent political family. Kennedy himself is running as a Democrat for the 2024 presidential election, challenging incumbent President Joe Biden.
While Biden and Harris questioned Trump's handling of the COVID-19 vaccine, they have since encouraged Americans to get inoculated. Their initial doubts about Trump's role in the vaccine process were rooted in concerns about transparency, political influence, and public health. These concerns reflected the broader unease felt by many Americans regarding the vaccine's development and rollout during a highly politicized pandemic.

Vaccine skepticism is higher among Republicans than Democrats, according to a 2020 survey
While there are no explicit mentions of Democratic presidential candidates being anti-vaccine, some candidates have been accused of promoting vaccine skepticism. In 2019, Democratic presidential candidate Tim Ryan praised a wellness blogger who expressed skepticism about vaccines. In his book, Ryan lauded the work of controversial blogger Vani Hari, who has been critical of vaccines. Ryan, however, claimed that he is "pro-vaccine" and has vaccinated himself and his children.
Robert F. Kennedy Jr., a prominent anti-vaccine activist and descendant of a prominent political family, filed a statement of candidacy for the 2024 US presidential election as a Democrat. Kennedy has appeared at events pushing conspiracy theories about the 2020 presidential election and has associated with people who cheered or downplayed the insurrection at the US Capitol on January 6, 2021.
While vaccine skepticism exists within both parties, surveys and polls have consistently shown that it is higher among Republicans than Democrats. A 2020 survey by the Pew Research Center found that half of US adults said they probably or definitely would not get a COVID-19 vaccine if it were available at the time. While vaccine skepticism was higher among Republicans, there was a notable increase among Democrats.
Another survey by Politico and Morning Consult found that while a majority of voters see the advantages of vaccination, there is a significant partisan divide. Among Democratic voters, 76% cared more about the potential health benefits of vaccines, while Republican voters were evenly split, with 51% caring more about potential health risks. This survey also revealed that while 64% of Democratic voters believed COVID-19 vaccines were "very" or "somewhat" safe for adults, only 52% of Republicans agreed.
The impact of political leaning on COVID-19 vaccine hesitancy has been studied, and a significant relationship has been found between the percentage of Republican supporters and rates of vaccine hesitancy. Counties with a higher percentage of Republican supporters tend to have specific characteristics, such as being rural, having a higher percentage of White residents, and lower levels of median house income. These factors, along with political affiliation, contribute to the higher vaccine skepticism observed among Republicans compared to Democrats.

Democrats have voiced concerns about the Trump administration rushing the COVID-19 vaccine
Several Democratic politicians have expressed concerns about the Trump administration rushing the development and deployment of a COVID-19 vaccine. They worry that the vaccine development process is being politicized and expedited, potentially compromising safety and effectiveness.
For instance, Democratic vice presidential nominee Kamala Harris stated that she would not rely solely on President Trump's assurance that a vaccine is safe and efficient. Similarly, presidential candidate Joe Biden remarked, "I trust vaccines, I trust scientists, but I don't trust Donald Trump."
A survey from the Pew Research Center conducted in September 2020 reflected these concerns. It found that half of U.S. adults were unlikely to get a COVID-19 vaccine if it were available at that time. While vaccine hesitancy was higher among Republicans, there was a notable increase in skepticism among Democrats.
Some experts and politicians have criticized the Trump administration for emphasizing the speed of vaccine development, including branding the effort "Operation Warp Speed." They argue that this emphasis on speed could undermine public trust in the vaccine's safety and efficacy.
Furthermore, there are concerns that political considerations, such as the upcoming election and economic concerns, could influence the approval process. Critics worry that the vaccine might be rushed to market without sufficient clinical trials and safety data, potentially impacting its effectiveness and public confidence.
It is worth noting that some Democratic figures, like Robert F. Kennedy Jr., have been associated with anti-vaccine sentiments. However, the broader Democratic concern appears to be centered around ensuring proper safety protocols and transparency in the vaccine development and approval process.
