A '''Vaccine''' provides acquired immunity to a specific [[disease]]. Vaccines are currently the most effective way of preventing infectious diseases.<ref>https://web.archive.org/web/20170829133723/https://www.cdc.gov/oid/docs/ID-Framework.pdf</ref> Vaccines 'train' the [[Immune system]] to become resistant to a certain disease by making it fight a smaller concentration of said disease.<ref>https://www.livescience.com/32617-how-do-vaccines-work.html</ref> Despite claims that vaccines can cause autism this is incorrect and there is no reason to be concerned.<ref>https://www.cdc.gov/vaccinesafety/concerns/autism.html</ref>

A '''vaccine''' is a pharmaceutical product containing an [[antigen]] designed to stimulate the production of antibodies against a particular disease or diseases.<ref>https://www.sciencenewsforstudents.org/article/explainer-what-vaccine</ref> While this sounds like a beneficial thing in theory, there is significant controversy on this topic. There are numerous reasons why some people prefer to avoid taking vaccines, but laws and other rules (often pushed into place by those who stand to make significant profit) frequently mandate them.

 

Vaccine manufacturers themselves admit to numerous severe harms caused by their products, in their packaging information which parents rarely see.

==Misconceptions==

==Problems==

Many people believe that vaccines are harmful, and while in some cases they can have side effects, it is much more dangerous to not vaccinate your child in most cases.<ref>https://www.cdc.gov/vaccines/parents/why-vaccinate/vaccine-decision.html</ref> Contrary to popular belief one of those side effects is not, in fact, [[Autism]].<ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2908388/</ref>

 

Many injuries from vaccination are admitted by the government, and severe potential side effects are disclosed on packaging labels that most parents never see. The sharp rise in [[autism]], which is generally considered incurable and afflicts 1 out of every 59 children, has a correlation with the increase in vaccination; the incidence of autism is greater in states where children receive more vaccines, such as [[New Jersey]] and [[North Carolina]].<ref>https://www.healthline.com/health/autism/autism-rates-by-state#2</ref> "The new estimate represents a 15% increase from two years prior and a 150% increase since 2000."<ref>https://www.cnn.com/2018/04/26/health/autism-prevalence-cdc/index.html</ref>  ''See generally'' [[vaccines and autism]].

 

Traditionally a few highly tested vaccines were recommended for children to protect against deadly or severe diseases, such as [[smallpox]] and [[polio]]. Beginning in the 1990s, however, profit-driven vaccine manufacturers lobbied states and pediatrician organizations to compel numerous additional vaccines for sexually transmitted or less dangerous diseases.  In addition, emotion based on inadequate information can cause over-vaccination.

 

17 US states have philosophical exemptions allowing parents to decline the vaccines; 47 states have religious exemptions; all states have medical exemptions,<ref>https://www.nvic.org/Vaccine-Laws/state-vaccine-requirements.aspx</ref><ref>http://www.vaccinesafety.edu/cc-exem.htm</ref> but they are hardest to obtain.  Some parents choose to [[homeschooling|homeschool]] rather than submit their children to numerous vaccinations as required by state laws, due to lobbying by vaccine manufacturers, as a condition of being in school.

 

Vaccines have substantial side effects, and many vaccines have significant morbidity and mortality associated with them. In the fiscal year 2017 alone, it is estimated that $220 million will be paid to victims of vaccines, and underpayments or improper denials of payment are common.<ref>http://www.wakingtimes.com/2017/05/09/whopping-vaccine-injury-payouts-us-fiscal-year-2017-released/</ref> More than Postvaccinial encephalitis is a known hazard of [[smallpox]] vaccine, for example. A recently introduced vaccine against human papilloma virus, the causative agent of cancer of the [[uterus|uterine]] cervix, has now been linked to a number of sudden deaths reported within days of its administration.<ref name=GardasilMM>Cockcroft, Lucy, "[https://www.telegraph.co.uk/news/main.jhtml?xml=/news/2007/10/29/njab129.xml Cervical cancer drug Gardasil linked to deaths]," ''[[London]] Daily Telegraph'', October 29, 2007. Retrieved November 10, 2007.</ref>

 

Bulging or swollen [[fontanelle]]s have been linked with many vaccines commonly given to infants, such as the diphtheria-[[tetanus]] (DPT) vaccine. Many families, out of concern for their child's health, have sought legal justice for the potential health damage.<ref>http://legaljustice4john.com/fontanellebulging.htm</ref>

 

Only live attenuated vaccines can still cause infection. All vaccines can cause illness, but this is commonly a hypersensitivity reaction (similar to an allergic response), not due to the disease itself. Very rarely a serious disease known as eczema vaccinatum can be caused by the smallpox vaccine. Vaccines that use pieces of pathogens often use a carrier virus in the injection. Those with very weak immune systems that are exposed to such a vaccine can become infected with the carrier virus and develop [[eczema]]. A recent case of this was reported in the United States after a military man was vaccinated with smallpox and his two-year-old son became ill.<ref>http://www.associatedcontent.com/article/183349/soldier_infects_toddler_son_with_lifethreatening.html AP article on eczema vaccinatum</ref>

 

A number of vaccination reactions are deemed serious enough to contraindicate further vaccinations of the same type. These include extensive swelling and redness at the injection site, prolonged fever, bronchospasm and laryngeal [[edema]] (narrowing of the airways causing difficulty in breathing), and collapse/seizures with or without unconsciousness and/or encephalitis.<ref>[http://www.gpnotebook.co.uk/simplepage.cfm?ID=2067071044 General Practice Notebook - vaccine reactions]</ref>

 

Most medical journals and the CDC are heavily influenced by vaccine manufacturers, and hence their published information about side effects is one-sided.  The packaging labels on vaccines are more candid.

 

*The Measles, Mumps, Rubella (MMR) vaccine has a 25% chance of causing [[arthralgia]] (joint pain) and a 10% chance of causing [[arthritis]]-like symptoms in women who are past puberty. This pain and stiffness begin 1–3 weeks after vaccination, persisting for 1 day to 3 weeks.<ref>[https://www.cdc.gov/vaccines/vpd-vac/combo-vaccines/mmr/faqs-mmr-hcp.htm]</ref>

*The MMR vaccine has a .00484% chance of causing [[thrombocytopenia]]. However, the measles and rubella both have much higher chances of causing thrombocytopenia.<ref>[http://adc.bmj.com/cgi/content/full/84/3/227 E Miller et al., Idiopathic thrombocytopenic purpura and MMR vaccine in ''Archives of Disease In Childhood'', 84:227-229]</ref>
