While infants receive about 4.4 milligrams* of aluminum in the first six months of life from vaccines, they receive more than that in their diet. It has been suggested that some diseases involving the brain, such as Alzheimer's disease, are caused by aluminum accumulation in brain tissues. Madin Darby Canine Kidney (MDCK) cell protein, MDCK cell DNA, Modified Mueller–Miller medium, Mueller–Hinton agar, Watson–Scherp medium, Vero (monkey kidney) cell culture, Medium 199, Mueller–Miller medium, synthetic or semisynthetic, Modified Mueller's media, synthetic or semisynthetic, Fenton media with bovine casein, Lathan medium derived from bovine, This page was last edited on 28 August 2020, at 16:02. Thiomersal was removed from UK vaccines between 2003 and 2005, and is no longer found in any of the childhood or adult vaccines routinely used in the UK. Jefferson T, Rudin M, Di Pietrantonj C. Adverse events after immunization with aluminium-containing DTP vaccines: systematic review of the evidence. Read the WHO statement and the EMA statement . But live vaccines also have some limitations. The authors reviewed the incidence of adverse events after exposure to aluminum-containing diphtheria, tetanus and pertussis (DTP), alone or in combination, compared with identical vaccines, either without aluminum or containing aluminum in different concentrations. They also absorb protein well, and stop the proteins in the vaccine sticking to the walls of a container during storage. The concern that aluminum in vaccines might be associated with a rare autoimmune disease called macrophagic myofasciitis has been refuted by previous studies. Compared to the number of viruses and bacteria in the environment that our bodies have to deal with every day, the amount of active ingredient in a vaccine is very small indeed. The initial list is based on information from the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) and thus limited to US-approved vaccines. The World Health Organization (WHO) and the European Medicines Agency (EMA, previously EMEA) have both stated that there is no evidence of risk from thiomersal in vaccines. Jefferson T, Rudin M, Di Pietrantonj C. Adverse events after immunization with aluminium-containing DTP vaccines: systematic review of the evidence. This makes it unlikely that any human material remains in the final vaccine. polysorbate 80, sorbitan trioleate and sodium citrate. You should consult your doctor or other healthcare provider if you need specific advice on vaccines for you or your child. However, studies have not consistently found increased levels of aluminum leading some to hypothesize that the aluminum accumulation may be the result of tissue damage rather than the cause of disease. A tiny quantity of yeast protein may remain in the 6-in-1 vaccine (Infanrix Hexa) and the Hepatitis B vaccines used in the UK, but there is no evidence that this can cause allergic reactions. Most single-dose vaccines do not contain thiomersal because they are used only once and so there is very little risk of contamination. If you have questions about any of the other ingredients or excipients used in vaccines, ask your GP for advice, or contact the vaccine manufacturer named on the vaccine's Patient Information Leaflet (PIL) or Summary of Product Characteristics (SPC) sheet. Recombinant vaccines are made using bacterial or yeast cells to manufacture the vaccine. Aluminium salts are used as food additives (for example in bread and cakes) and in drugs such as antacids, and aluminium is widely used in food packaging. Aluminum is used for manufacturing of airplanes, siding, roofing materials, paints, pigments, fuels and cigarette filters. These stimulate the immune system but cannot cause disease. Acad Pediatr 2018;18:161-165. This is inserted into other cells to make them produce large quantities of active ingredient for the vaccine (usually just a single protein or sugar). By contrast it is estimated that 100 trillion bacteria live on the skin of the average human being, each of them containing many thousands of proteins which constantly challenge our immune systems. These are listed on vaccine information leaflets as ‘excipients’ (inactive ingredients). The only exception is children who have a history of severe anaphylaxis to eggs which has previously needed treatment in intensive care. Keith LS, Jones DE, Chou CHSJ. The oral rotavirus vaccine (Rotarix) contains about a gram of sugar (sucrose) to give it a pleasant taste. These are all emulsifiers which stop the squalene oil separating out from the water in the vaccine. Department of Health advice is that the HPV vaccine can be given to yeast allergy sufferers because the final product does not contain any yeast. There is also detailed information about the safety of thiomersal on the US Food and Drug Administration's pages . Goullé JP, Grangeot-Keros L. Aluminum and vaccines: Current state of knowledge. Children taking large amounts of aluminum-based medications have also been found to suffer from this bone disorder. Tiny quantities of thiomersal are often used in multi-dose vaccines to stop them becoming contaminated once they are opened. In the UK you can also contact the Medicines and Healthcare products Regulatory Agency (MHRA) which regulates medicines, including vaccines, in the UK. Aluminium is not used by the body. Aluminum hydroxide, aluminum phosphate, amino acids, formalin, Madin Darby Canine Kidney (MDCK) cell protein. This is because the ovalbumin content is very low. These are the parts of the vaccine made from viruses or bacteria (also called ‘antigens’). Aluminum is found in numerous foods and beverages including fruits and vegetables, beer and wine, seasonings, flour, cereals, nuts, dairy products, baby formulas, and honey. We can’t answer all the individual queries we get, but we will use your suggestions and questions to improve the website. Doctors have carefully studied this issue and confirmed that there is no increased risk of reactions to the MMR vaccine in children who are allergic to eggs. Just 1 or 2 doses of most live vaccines can give you a lifetime of protection against a germ and the disease it causes. Advice on this changed more than ten years ago. Hundreds of thousands of individual vaccines could be made from a single teaspoon of active ingredient. However, most children recovered from their symptoms. The amount of aluminium present in vaccines is small - less than 2 milligrams of the salts, and less than a milligram of actual aluminium. The Vaccine Knowledge Project is funded by the NIHR Oxford Biomedical Research Centre and the Oxford Martin School. ©2020 The Children’s Hospital of Philadelphia. Medical content reviewed by Professor Andrew Pollard.Please click here to contact us if you have comments about the Vaccine Knowledge website. Like vaccines, most of the medicines we use also contain excipients. For vaccines used in the UK, human cell strains are used to grow viruses for these vaccines: The cell strains currently used (called WI-38 and MRC-5) were started in the 1960s using lung cells taken from two aborted foetuses. Levels of exposure slightly above the MRL were also likely to be safe given the manner in which the MRL is calculated. Also listed are substances used in the manufacturing process. Aluminum-containing vaccines have been used for decades and have been given to more than 1 billion people without problem. See more information about the SNIFFLE study and an information sheet from Public Health England showing the ovalbumin content of flu vaccines in the current flu season. A study from 2008 showed that the ethyl mercury in thiomersal does not appear to accumulate in the bodies of even very small babies. The exact amounts of aluminium per dose are listed for each vaccine: MF59 is used in only one vaccine licensed in the UK: Fluad, a flu vaccine introduced in the 2018-19 flu season for adults aged 65 and older (see the page on the Inactivated Flu Vaccine). In the UK schedule this applies to these vaccines: Viruses for these vaccines are grown on Vero cells. Aluminium is the most common metal in the earth’s crust and we are exposed to it all the time. Vaccine 2011; 29:9538-9543. This is because the flu virus is grown on fertilised hens' eggs. citric acid, used extensively in foods and drinks. Sorbitan trioleate is a compound made from oleic acid (a natural fatty acid) and sorbitol, also found naturally in fruits and other foods. However, there was no evidence that thiomersal in vaccines caused harm. A trace may remain in one of the Pre-school Booster vaccines (Repevax). There are two reasons for this: they are cheaper, and they are easier to produce quickly in large quantities in the event of an epidemic. These yeast cells are then able to produce one of the surface proteins from the hepatitis B virus, and this is purified and used as the active ingredient in the vaccine. People with a known allergy to gelatine should seek expert advice before receiving vaccines containing gelatine. In the UK schedule, both the Nasal Flu Vaccine (Fluenz Tetra) and two of the Inactivated Flu Vaccines may contain traces of egg proteins. This is a cell strain started in the 1960s using kidney cells from an African green monkey. Aluminum is the third most abundant element after oxygen and silicon, and it is the most abundant metal, making up almost 9 percent of the earth's crust. Vaccines containing adjuvants are tested extensively in clinical trials before being licensed. These are products such as aluminium salts that help to improve the immune response to vaccines, or products that act as preservatives and stabilisers (for example, gelatine or human serum albumin). See our page on 'Types of vaccine'. These children should be referred to specialists for immunisation in hospital. Sorbitol may also be present in one of the chickenpox vaccines (Varilrix). Dans ladite formulation l'antigène est adsorbée sur du phosphate d'aluminium. Breast-fed infants ingest about 7 milligrams, formula-fed infants ingest about 38 milligrams, and infants who are fed soy formula ingest almost 117 milligrams of aluminum during the first six months of life. Like all other living things, viruses and bacteria need to be kept at the right pH (acid/alkaline level). For example, the needle tip of the syringe may be protected with a latex bung. Aluminum salts, monophosphoryl A (a detoxified bacterial component), and squalene (a compound of the body’s normal cholesterol synthesis pathway) are the only materials that can be used as adjuvants in the United States. Aluminum can be found in food-related products including pots and pans; storage containers, such as beverage cans; and foil. Compared to its use in foods, there is very little polysorbate 80 in vaccines. Materials in this section are updated as new information and vaccines become available. Granulomas are not dangerous but can be irritating and last for months or even years. A small piece of DNA is taken from the virus or bacterium that we want to protect against. The 2020-2021 flu season is not shaping up to be a normal one. Ameratunga R, Gills D, Gold M, et al. A number of different products are used in very small quantities to help keep the pH balance right while vaccines are being manufactured. These are neomycin, streptomycin, polymyxin b, gentamicin and kanamycin. Aluminium salts are found in these vaccines used routinely in the UK. Antibiotics are used in the manufacture of the following vaccines used in the UK: Egg allergy is quite common in children under 5, and much more common in children than in adults. They were not, however, associated with serious adverse events. L'invention se rapporte également à un vaccin multivalent servant à améliorer ou à traiter plusieurs états pathologiques. A 2014 Australian study of over a million children found no evidence of a link between thiomersal in vaccines and autism development. If you look up some vaccine ingredients on the internet you may read that they could be harmful, but most of them are present in vaccines in amounts that are completely normal for our bodies. These products include: For some vaccines, the active ingredient is grown in laboratories on cultures that contain human cells. Note: Thimerosal content less than 0.3 µg. This information is also available in Arabic , Bengali and Urdu . A study from 2011 modelled the impact of aluminium from diet and vaccines in infants, and concluded that the total amount of aluminium absorbed from both sources was likely to be less than the weekly safe intake level. It is used in the production of some vaccines to inactivate toxins from bacteria and viruses (for example, poliovirus, Hepatitis B antigen, and diphtheria and tetanus toxins). All vaccine ingredients are present in very small quantities, and there is no evidence that they cause harm in these amounts. Also listed are substances used in the manufacturing process. For example, to make the hepatitis B vaccine, part of the DNA from the hepatitis B virus is inserted into the DNA of yeast cells. Children aged 9 to 13 months, excluding those who received aluminum-containing pharmaceuticals, were evaluated for blood and hair aluminum levels, vaccination history, and cognitive, language and motor development scores. Other non-routine vaccines, such as yellow fever vaccine, may also contain egg proteins. Unlike food products, the list of vaccine ingredients may include products used during the manufacturing process, even if they do not remain in the finished product. Polysorbate 80 and sodium citrate are commonly used in food and drink. The measles and mumps viruses are grown on a culture which contains chick embryo cells (not on eggs). A few vaccines in the UK schedule are made using recombinant DNA technology. All other ingredients weigh a few milligrams (thousandths of a gram) or even less. La plupart des vaccins inactivés dans le monde contiennent des adjuvants qui permettent au système immunitaire de répondre de manière efficace et donc de défendre l’organisme contre les infections ciblées par le vaccin. However, it also states that if the population is exposed to ‘considerable dangers to their health’ through diseases such as rubella (German measles), then ‘vaccines with moral problems pertaining to them may also be used on a temporary basis’. Other vaccines in use in the UK may use bovine products in their manufacture, but this is not stated on their SPCs. An adjuvant is vaccine component that boosts the immune response to the vaccine. This list of vaccine ingredients indicates the culture media used in the production of common vaccines and the excipients they contain, as published by the United States Centers for Disease Control and Prevention and Food and Drug Administration.Vaccine ingredients and production in other nations are substantially the same. For example, many vaccines contain salts based on sodium and potassium (see the section on 'Acidity regulators'), which are essential for life. In the past, people with an egg allergy were advised not to receive the MMR vaccine. Lancet Infect Dis 2004;4:84-90. Children’s Hospital of Philadelphia is a charitable 501(c)(3) nonprofit organization. For medical concerns, including decisions about vaccinations, medications and other treatments, you should always consult your physician or, in serious cases, seek immediate assistance from emergency personnel. These are products such as aluminium salts that help to improve the immune response to vaccines, or products that act as preservatives and stabilisers (for example, gelatine or human serum albumin).These are listed on vaccine information leaflets as ‘excipients’ (inactive ingredients). In 2005 the Vatican’s Pontifical Academy for Life issued a statement called ‘Moral reflections on vaccines prepared from cells derived from aborted human foetuses’. Given the quantities of aluminum we are exposed to on a daily basis, the quantity of aluminum in vaccines is miniscule. The authors identified two studies refuting the claim for autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) as suggested by Shoenfeld and coworkers. Evidence refuting the existence of autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA). Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response. Sorbitol is usually harmless, but people with an allergy to sorbitol, or with rare inherited problems of fructose intolerance, should not receive vaccines containing sorbitol. Sorbitol is produced naturally in the human body and also found in fruit and berries. Because they contain a small amount of the weakened live virus, some people should talk to their healt… Stories about people affected by infectious diseases, Human cell strains, animal cell strains and GMOs, The key ingredient in all vaccines is one or more, US National Institute of Allergy and Infectious Disease, Australian study of over a million children, Joint Committee on Vaccination and Immunisation, risk posed by bovine products used in vaccine manufacture, Medicines and Healthcare products Regulatory Agency (MHRA). Added ingredients are present in very small quantities (usually a few milligrams). For further information about vaccine ingredients, contact the manufacturer of the vaccine. Only one vaccine used in the UK contains genetically modified organisms (GMOs). The exception to this is the small number of people who may be severely allergic to a vaccine ingredient, even if it is present only in trace amounts (for example, egg proteins or antibiotics used in vaccine manufacture). Instead they can be grown on cultures that are rich in proteins, vitamins and salts. Some bacteria do not need to be grown on human or animal cells. It is an adjuvant which helps to strengthen and lengthen the immune response to the vaccine. It is cleared from the blood in 30 days, and the evidence suggests that it is passed out in the baby’s stool (poo). What is a vaccine, and how do vaccines work? These have been prepared in response to the recognition of BSE in the 1980s and are regularly updated. La formulation de vaccin de l'invention est destinée à la prévention des infections d'Haemophilius d'Influenzae de type B (Hib). This is potentially a risk for people who are severely allergic to bovine products. In one study, lupus patients were found to have no increase in exacerbations after receiving a hepatitis B vaccine containing an aluminum adjuvant. The quantities of aluminum present in vaccines are low and are regulated by the Center for Biologics Evaluation and Research (CBER). This means that there is not enough egg protein in the MMR vaccine to cause allergic reactions, so children with severe egg allergies can safely receive the MMR. There have been a tiny number of cases of allergic reaction to vaccines containing gelatine (about one case for every 2 million doses of vaccine). The abortions were legal and agreed to by the mothers, but they were not performed for the purpose of vaccine development. This list of vaccine ingredients indicates the culture media used in the production of common vaccines and the excipients they contain, as published by the United States Centers for Disease Control and Prevention and Food and Drug Administration.
