Vaccine hesitancy is a delay in acceptance, or refusal of vaccines despite the availability of vaccine services. The term covers outright refusals to vaccinate, delaying vaccines, accepting vaccines but remaining uncertain about their use, or using certain vaccines but not others. The scientific consensus that vaccines are generally safe and effective is overwhelming. Vaccine hesitancy often results in disease outbreaks and deaths from vaccine-preventable diseases. Therefore, the World Health Organization characterizes vaccine hesitancy as one of the top ten global health threats.

Riko Muranaka is a medical doctor, journalist and recipient of the 2017 John Maddox Prize for fighting to reduce cervical cancer and countering misinformation about the human papilloma virus (HPV) vaccine dominating the Japanese media, despite facing safety threats. Despite the lack of evidence, the HPV vaccine is infamous in Japan due to misattributed adverse effects, with government suspending promotion and coverage. While the World Health Organization (WHO) safety and efficacy information about the vaccine is consistent with Muranaka's reporting, a court ruled against Muranaka in an unrelated slander lawsuit in 2016 for claims of alleged fabrication. Under threat of legal harassment by antivaccine activists, publishers declined some of her works including a book on the HPV vaccine.

Children's Health Defense is an American 501(c)(3) nonprofit activist group mainly known for anti-vaccine propaganda and has been identified as one of the main sources of misinformation on vaccines. Founded under the name World Mercury Project in 2011, it is chaired by Robert F. Kennedy Jr. The group has been campaigning against various public health programs, such as vaccination and fluoridation of drinking water. The group has been contributing to vaccine hesitancy in the United States, encouraging citizens and legislators to support anti-vaccine regulations and legislation. Arguments against vaccination are contradicted by overwhelming scientific consensus about the safety and effectiveness of vaccines.

Dame Sarah Catherine Gilbert is a British vaccinologist who is a Professor of Vaccinology at the University of Oxford and co-founder of Vaccitech. Gilbert specialises in the development of vaccines against influenza and emerging viral pathogens. She led the development and testing of the universal flu vaccine, which underwent clinical trials in 2011. On New Year's Day 2020 Gilbert read on ProMED-mail about four people in China suffering from a strange pneumonia of unknown cause, in Wuhan, China. Within two weeks a vaccine had been designed at Oxford against the new pathogen. On 30 December 2020, the Oxford–AstraZeneca COVID-19 vaccine she co-developed with the Oxford Vaccine Group was approved for use in the United Kingdom. As of January 2022 more than 2.5 billion doses of the vaccine have been released to more than 170 countries worldwide.

Plandemic: The Hidden Agenda Behind Covid-19 and Plandemic: Indoctornation are a 2020 conspiracy theory video and film, respectively. Both were produced by Mikki Willis and promote misinformation about the COVID-19 pandemic. They feature Judy Mikovits, a discredited American researcher who has been described as an anti-vaccine activist. The first video, in addition to promoting various conspiracy theories, also features Willis and Mikovits discussing viruses in general and Mikovits herself. Willis produced the first video with a low budget under the name of his production company Elevate Films. Three months after the video's Internet release, the second film Plandemic: Indoctornation, which also includes other people, was released by another distributor.

Misinformation related to vaccination and immunization circulates in mass media and social media. Intentional spreading of false information and conspiracy theories have also been propagated by the general public and celebrities. Misinformation related to vaccination fuels vaccine hesitancy and thereby results in disease outbreaks. Although opposition to vaccination has existed for centuries, the internet and social media has recently facilitated the spread of vaccine-related misinformation. Unsubstantiated safety concerns related to vaccines are often presented on the internet as scientific information.

The Lancet letter was a statement made in support of scientists and medical professionals in China fighting the outbreak of COVID-19, and condemning theories suggesting that the virus does not have a natural origin, which it referred to as "conspiracy theories". The letter was published in The Lancet on February 19, 2020, and signed by 27 prominent scientists, gaining a further 20,000 signatures in a Change.org petition. The letter generated significant controversy over the alleged conflict of interest of its authors, and the chilling effect it had on scientists proposing that the COVID-19 lab leak theory be investigated.
