Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, they help prevent sickness from an infectious disease. When a sufficiently large percentage of a population has been vaccinated, herd immunity results. Herd immunity protects those who may be immunocompromised and cannot get a vaccine because even a weakened version would harm them. The effectiveness of vaccination has been widely studied and verified. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the elimination of diseases such as polio and tetanus from much of the world. However, some diseases, such as measles outbreaks in America, have seen rising cases due to relatively low vaccination rates in the 2010s – attributed, in part, to vaccine hesitancy. According to the World Health Organization, vaccination prevents 3.5–5 million deaths per year.
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease. The safety and effectiveness of vaccines has been widely studied and verified. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and recognize further and destroy any of the microorganisms associated with that agent that it may encounter in the future.
In academic publishing, a retraction is a mechanism by which a published paper in an academic journal is flagged for being seriously flawed to the extent that their results and conclusions can no longer be relied upon. Retracted articles are not removed from the published literature but marked as retracted. In some cases it may be necessary to remove an article from publication, such as when the article is clearly defamatory, violates personal privacy, is the subject of a court order, or might pose a serious health risk to the general public.
Science by press conference or science by press release is the practice by which scientists put an unusual focus on publicizing results of research in the news media via press conferences or press releases. The term is usually used disparagingly, to suggest that the seekers of publicity are promoting claims of questionable scientific merit, using the media for attention as they are unlikely to win the approval of the scientific community.
Vaccine hesitancy is a delay in acceptance, or refusal, of vaccines despite the availability of vaccine services and supporting evidence. The term covers refusals to vaccinate, delaying vaccines, accepting vaccines but remaining uncertain about their use, or using certain vaccines but not others. Although adverse effects associated with vaccines are occasionally observed, 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.
A subunit vaccine is a vaccine that contains purified parts of the pathogen that are antigenic, or necessary to elicit a protective immune response. Subunit vaccine can be made from dissembled viral particles in cell culture or recombinant DNA expression, in which case it is a recombinant subunit vaccine.
Harald Walach is a German parapsychologist and advocate of alternative medicine.
The Séralini affair was the controversy surrounding the publication, retraction, and republication of a journal article by French molecular biologist Gilles-Éric Séralini. First published by Food and Chemical Toxicology in September 2012, the article presented a two-year feeding study in rats, and reported an increase in tumors among rats fed genetically modified corn and the herbicide RoundUp. Scientists and regulatory agencies subsequently concluded that the study's design was flawed and its findings unsubstantiated. A chief criticism was that each part of the study had too few rats to obtain statistically useful data, particularly because the strain of rat used, Sprague Dawley, develops tumors at a high rate over its lifetime.
Gilles-Éric Séralini is a French molecular biologist, political advisor and activist on genetically modified organisms and foods. He is of Algerian-French origin. Séralini has been a professor of molecular biology at the University of Caen since 1991, and is president and chairman of the board of CRIIGEN.
Cry1Ac protoxin is a crystal protein produced by the gram-positive bacterium, Bacillus thuringiensis (Bt) during sporulation. Cry1Ac is one of the delta endotoxins produced by this bacterium which act as insecticides. Because of this, the genes for these have been introduced into commercially important crops by genetic engineering in order to confer pest resistance on those plants.
Environmental Sciences Europe is a peer-reviewed scientific journal covering all aspects of environmental science. It was established in 1989 as Umweltwissenschaften und Schadstoff-Forschung, obtaining its current name in 2011. It is published by Springer Science+Business Media and the editor-in-chief is Henner Hollert. Since 2011, the journal has been open access.
Stephanie Seneff is an American computer scientist and anti-vaccinationist. She is a senior research scientist at the Computer Science and Artificial Intelligence Laboratory (CSAIL) of the Massachusetts Institute of Technology (MIT). Working primarily in the Spoken Language Systems group, her research at CSAIL relates to human–computer interaction, and algorithms for language understanding and speech recognition. In 2011, she began publishing controversial papers in low-impact, open access journals on biology and medical topics; the articles have received "heated objections from experts in almost every field she's delved into," according to the food columnist Ari LeVaux.
Christopher Ariel Shaw is a Canadian neuroscientist and professor of ophthalmology at the University of British Columbia.
Glyphosate-based herbicides are usually made of a glyphosate salt that is combined with other ingredients that are needed to stabilize the herbicide formula and allow penetration into plants. The glyphosate-based herbicide Roundup was first developed by Monsanto in the 1970s. It is used most heavily on corn, soy, and cotton crops that have been genetically modified to be resistant to the herbicide. Some products include two active ingredients, such as Enlist Duo which includes 2,4-D as well as glyphosate. As of 2010, more than 750 glyphosate products were on the market. The names of inert ingredients used in glyphosate formulations are usually not listed on the product labels.
Extensive investigation into vaccines and autism has shown that there is no relationship between the two, causal or otherwise, and that vaccine ingredients do not cause autism. Vaccinologist Peter Hotez researched the growth of the false claim and concluded that its spread originated with Andrew Wakefield's fraudulent 1998 paper, with no prior paper supporting a link.
A COVID‑19 vaccine is a vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID‑19).

Misinformation related to immunization and the use of vaccines circulates in mass media and social media in spite of the fact that there is no serious hesitancy or debate within mainstream medical and scientific circles about the benefits of vaccination. Unsubstantiated safety concerns related to vaccines are often presented on the internet as being scientific information. A large proportion of internet sources on the topic are mostly inaccurate which can lead people searching for information to form misconceptions relating to vaccines.
Noora is a COVID-19 vaccine candidate developed by Baqiyatallah University of Medical Sciences in collaboration with Plasma Darman Sarv Sepid Co. in Iran. Introduced in June 2021, it was announced as having "successfully passed the first phase of its clinical trial" two months later.
Turbo cancer is an anti-vaccination conspiracy theory alleging that people vaccinated against COVID-19, especially with mRNA vaccines, are suffering from a high incidence of fast-developing cancers. Although the idea has been spread by a number of vaccine opponents, including several health professionals, turbo cancer is not supported by cancer research, and there is no evidence that COVID-19 vaccination causes or worsens cancer.
