Побочные эффекты вакцинации: факты и заблуждения.

A vaccine adverse event (VAE), sometimes referred to as a vaccine injury, is an adverse event believed to have been caused by vaccination. The World Health Organization (WHO) knows VAEs as Adverse Events Following Immunization (AEFI). AEFIs can be related to the vaccine itself (product or quality defects), to the vaccination process (administration error or stress related reactions) or can occur independently from vaccination (coincidental). Most vaccine adverse events are mild. Serious injuries and deaths caused by vaccines are very rare, and the idea that severe events are common has been classed as a "common misconception about immunization" by the WHO. Some claimed vaccine injuries are not, in fact, caused by vaccines; for example, there is a subculture of advocates who attribute their children's autism to vaccine injury, despite the fact that vaccines do not cause autism. Claims of vaccine injuries appeared in litigation in the United States in the latter part of the 20th century. Some families have won substantial awards from sympathetic juries, even though many public health officials have said that the claims of injuries are unfounded. In response, several vaccine makers stopped production, threatening public health, resulting in laws being passed at several points to shield makers from liabilities stemming from vaccine injury claims. most side effects are minor, primarily including sore arms or a mild fever. As the success of immunization programs increases and the incidence of disease decreases, public attention shifts away from the risks of disease to the risk of vaccination. Allegations particularly focus on disorders claimed to be caused by the MMR vaccine and thiomersal, a preservative used in vaccines routinely given to U. S. infants prior to 2001. Current scientific evidence does not support claims of vaccines causing various disorders. The debate is complicated by misconceptions around the recording and reporting of adverse events by anti vaccination activists. According to authorities, anti vaccination websites greatly exaggerate the risk of serious adverse effects from vaccines and falsely describe conditions such as autism and shaken baby syndrome as vaccine injuries, leading to misconceptions about the safety and effectiveness of vaccines. This has had the result of stigmatizing autistic people and the parents who had them immunized. Many countries, including Canada, Germany, Japan, and the United States have specific requirements for reporting vaccine related adverse effects, while other countries including Australia, France, and the United Kingdom include vaccines under their general requirements for reporting injuries associated with medical treatments. A number of countries have programs for the compensation of injuries alleged to have been caused by a vaccination. The VICP was adopted in response to an earlier scare over the pertussis portion of the DPT vaccine. These claims were later generally discredited, but some U. S. lawsuits against vaccine makers won substantial awards; most makers ceased production, and the last remaining major manufacturer threatened to do so. As of October 2019, $4.2 billion in compensation (not including attorneys fees and costs) has been awarded. VICP uses a streamlined system for litigating vaccine injury claims under which the claimant must show that the vaccine caused the injury, but just as in litigation for injury by any other product, they are not required to establish it was anyone's fault (i. e. negligence need not be proven) Claims that are denied can be pursued through civil lawsuits, though this is rare, and the statute creating the VICP also imposes substantial limitations on the ability to pursue such lawsuits. The VICP covers all vaccines listed on the Vaccine Injury Table

In addition, an award may only be given if the claimant's injury lasted for more than 6 months after the vaccine was given, resulted in a hospital stay and surgery or resulted in death. Awards are based on medical expenses, lost earnings and pain and suffering (capped at $250,000). From 1988 until March 3, 2011, 5,636 claims relating to autism, and 8,119 non autism claims, were made to the VICP. 2,620 of these claims, one autism related, were compensated, with 4,463 non autism and 814 autism claims dismissed; awards (including attorney's fees) totaled over $2 billion. The VICP also applies to claims for injuries sustained before 1988; there were 4,264 of these claims of which 1,189 were compensated with awards totaling $903 million. As of October 2019, $4.2 billion in compensation (not including attorneys fees and costs) has been awarded over the life of the program. For example, for vaccines containing tetanus toxoid (e. g., DTaP, DTP, DT, Td, or TT), anaphylaxis within four hours or brachial neuritis between two and twenty eight days after administration, may be compensated.

Established by PREP Act, in the case of pandemic, epidemic, or other major security threat requiring a medical countermeasures, such as vaccines and medications, the CICP provides compensation to eligible individuals for serious physical injuries or death. Covid 19 vaccines are covered under the program.

The Vaccine Adverse Event Reporting System (VAERS) is a passive surveillance program administered jointly by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC). VAERS is intended to track adverse events associated with vaccines. VAERS collects and analyzes information from reports of adverse events that occur after the administration of US licensed vaccines. VAERS has several limitations, including underreporting, unverified reports, inconsistent data quality, and inadequate data about the number of people vaccinated. Due to the program's open and accessible design and its allowance of unverified reports, incomplete VAERS data is often used in false claims regarding vaccine safety.

The Vaccine Safety Datalink (VSD), funded by the Centers for Disease Control, is composed of databases from several organizations containing information regarding health outcomes for millions of US citizens and to enhance assessment of vaccine injuries. It was designed to allow for such things as comparisons between vaccinated and non vaccinated populations, and for the identification of possible groups at risk for adverse events.

The Vaccine Damage Payment Act 1979 governs AEFIs in the UK, and sets up the Vaccine Damage Payment Scheme (VDPS).

Under the VDPS, it is thought that thousands of unsuccessful claims have been made. The maximum payment per claim is currently £120,000. The 'disability threshold' before payments are granted is 60%. The scheme covers vaccinations for illnesses such as tetanus, measles, tuberculosis, and meningitis C. As of 2005, the British government had paid out £3.5 million to vaccine injury patients since 1997. Until the advent of COVID 19, disabled vaccine injury patients were allowed to file a claim up to the age of 21. On the 2 December 2020, government agreed under regulation secondary to the 1979 Act the statutory £120,000 blanket payout for any person provably damaged by the vaccine, and by the same addition of COVID 19 to the list, government approved Covax manufacturers were exempted from legal pursuit. Individuals who provide the vaccine (and thus are permitted by government to do so) are also protected.
