Andrew Wakefield published a study in 1998 claiming a link between the MMR vaccine and autism. This led to reduced vaccination rates. An investigation found Wakefield committed ethical violations and distorted facts, and he was stripped of his medical license. Multiple large studies have found no link between the MMR vaccine and autism. Wakefield's claims have been fully discredited.
Vaccines and their effect on public health
The document discusses the history and science of vaccines. It begins with a brief history of vaccines from ancient concepts of inoculation to Jonas Salk's creation of the polio vaccine in the 1950s. It then explains how most vaccines work by using weakened or dead microbes to stimulate the immune system to create memory cells that provide long-term protection. The document also notes that vaccines have led to the eradication of deadly diseases and establish herd immunity. However, it acknowledges there is an anti-vaccine debate centered around disproven claims about links between vaccines and autism or harmful ingredients like thimerosal.
Vaccination measles
The document discusses concerns about the MMR vaccine and a potential link to autism. It provides details on vaccine ingredients including fetal bovine serum and human fetal cells. It summarizes testimony from a Congressional hearing linking vaccines to autism, including findings of measles virus in the gut and autoimmune responses post-vaccination. The document also discusses the history of measles and implications of vaccination and waning immunity over time.
BTEC 4C: Infectious diseases and vaccines
The document discusses infectious diseases and how vaccination can prevent them. It defines a pathogen as a microorganism that causes disease and lists bacteria and viruses as examples. It describes how bacteria and viruses can enter the body and cause infectious diseases. It then explains how vaccinations work by exposing the body to inactive or dead forms of pathogens to allow the immune system to develop antibodies and memory cells to quickly fight off future infections without causing illness.
Vaccine`s history
The document discusses the history and future of vaccines. It begins by explaining how vaccines work by tricking the immune system to produce antibodies to fight a harmless form of the virus. Next, it discusses how while hypodermic injection is most common, scientists are searching for alternative delivery methods. The document then discusses how Edward Jenner conducted the first vaccination against smallpox in the late 1700s and how Louis Pasteur developed the first vaccine against rabies in 1885. Finally, it notes that as more vaccines were developed, large groups like soldiers began being vaccinated against diseases during World Wars I and II.
Polio vaccine
The document discusses the poliovirus, which causes poliomyelitis (polio). It causes paralysis in about 1% of cases. Two main vaccines were developed - the live attenuated oral polio vaccine (OPV) by Albert Sabin in the 1950s and the inactivated polio vaccine (IPV) by Jonas Salk in the 1950s. OPV uses weakened live virus and provides both intestinal and serum immunity but carries a small risk of vaccine-derived polio. IPV uses killed virus and provides only serum immunity but is very safe. Both vaccines have been highly effective at reducing polio worldwide.

1. Chickenpox is caused by the varicella zoster virus and infection during pregnancy can increase risks for the fetus and mother.
2. For the fetus, infection during the first or second trimester increases the risk of congenital varicella syndrome which can cause limb abnormalities and organ damage in up to 12% of cases.
3. For the mother, infection during the third trimester increases the risk of pneumonia which has a mortality rate of up to 14% without treatment.
Vaccination Standards in Adults and Pediatrics
This document discusses vaccination standards and immunization schedules for adults and pediatrics in the United States for 2019. It was authored by Dr. Luis J. Lugo Vélez and covers information from the Advisory Committee on Immunization Practices (ACIP) such as their role in developing vaccination recommendations and meeting schedule. It also includes the recommended vaccination schedules for children/adolescents and notes from various schedules. Additionally, it discusses diseases prevented by vaccines and compares morbidity rates pre-and-post widespread vaccination.
Vaccine and vaccination
Vaccines work by exposing the immune system to agents that resemble disease-causing pathogens, causing the body to develop immunity to them. There are several types of vaccines, including live attenuated vaccines containing weakened live pathogens, inactivated vaccines containing killed pathogens, toxoid vaccines containing inactivated toxins, and subunit vaccines containing fragments of pathogens. Vaccines are administered through various routes such as intramuscular, subcutaneous, oral, intranasal, and intradermal injection depending on the vaccine. Proper vaccine storage, administration technique, and timing are important for vaccine effectiveness.
Vaccine & vaccination
Vaccines provide active acquired immunity by exposing the immune system to weakened or killed forms of disease-causing microbes. Edward Jenner pioneered vaccination in the late 18th century by showing that inoculation with cowpox protected against smallpox. Since then, vaccines have been developed for many diseases like polio, diphtheria, measles and more through the work of scientists like Pasteur and others. Vaccines are administered through various routes and provide long-lasting immunity through both active natural and artificial means.
pulse polio
Pulse Polio is an immunization campaign established by the government of India to eliminate poliomyelitis (polio) in India by vaccinating all children under the age of five years against the polio virus.
The project fights polio through a large-scale , pulse vaccination programme and monitoring for poliomyelitis cases.
Vellore(Tamil Nadu) was the first Indian state to become 100% polio-free through the pulse strategy, and rest of India adopted the strategy in 1995.

Vaccination
1) Vaccines are biological preparations that help improve immunity against specific diseases. They contain weakened or killed forms of pathogens that stimulate immune system memory without causing illness.
2) Edward Jenner developed the first vaccine in 1796 using cowpox to provide immunity to smallpox. There are several types of vaccines including live attenuated, inactivated, subunit, toxoid, and recombinant vector vaccines.
3) Vaccines work by exposing the immune system to antigens from pathogens. This triggers production of antibodies and memory cells that can fight the pathogen if exposed in the future, providing immunity. While vaccines have many benefits like disease prevention and eradication, some risks also exist.
Vaccination and health risk due to vaccination- a perspective
This document discusses vaccination risks and perspectives from a study conducted in India. It begins by defining vaccination and how it induces immunity. It then analyzes risks associated with vaccination, including immunization errors from improper administration and non-immunization risks like Guillain-Barré syndrome and aseptic meningitis. Data is presented on increased incidence rates of these conditions post-vaccination. The document also examines vaccine-specific side effect rates and challenges with vaccination programs in India. It concludes by emphasizing the need for proper awareness, training, storage, and administration to mitigate risks while recognizing vaccination's overall public health benefits.

ROLE OF NANOPATCHES
Nano patches can be used to deliver vaccines through the skin for epicutaneous immunization. They have micro-projections containing the vaccine that deliver it into the epidermis, which is rich in immune cells called Langerhans cells. These cells then carry the antigen to lymph nodes where it stimulates antibody production. Nano patch vaccines could help reduce costs by providing needle-free delivery, making vaccination easier and safer especially in developing countries by eliminating needle stick injuries and reuse. Further research is still needed but nano patch vaccination shows potential for improved vaccine delivery and uptake.
Jenner And Smallpox
The document discusses the deadly smallpox disease in the 18th century and Edward Jenner's pioneering work developing the smallpox vaccine. It describes how Jenner observed that milkmaids who had previously contracted cowpox did not get smallpox, leading him to test the theory that cowpox protected against smallpox. In 1796, Jenner conducted an experiment where he took cowpox matter from a milkmaid and inoculated an 8-year-old boy, who was later exposed to smallpox but did not become ill, demonstrating the effectiveness of vaccination. Though initially met with some skepticism, vaccination was widely adopted and led to the eradication of smallpox by 1980.
Vegetarian
There are different types of vegetarians such as lacto-ovo vegetarians who eat dairy and eggs, lacto-vegetarians who eat dairy, and vegans who eat no animal products. Being vegetarian provides health benefits like lower risks for various diseases. Vegetarians must ensure they get enough protein, calcium, iron, and vitamin B12 through their diets. The document recommends buying local organic foods and supporting local farms, as well as discussing raising vegetarian children and soy in schools.
The positive effects of community policing
Community policing aims to establish relationships between police officers and the community to prevent crime. It works by having officers problem solve with community members using models like SARA and POP. These involve scanning issues, analyzing problems, responding to problems, and assessing results. Studies show community policing reduces crime through cooperation and addressing community concerns, making it an effective strategy for lowering crime rates.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
