Vaccine, suspension of weakened, killed, or fragmented microorganisms or toxins or of antibodies or lymphocytes that is administered primarily to prevent disease. A vaccine can confer active immunity against a specific harmful agent by stimulating the immune system to attack the agent. Once stimulated by a vaccine, the antibody-producing cells, called B lymphocytes, remain sensitized and ready to respond to the agent should it ever gain entry to the body. A vaccine may also confer passive immunity by providing antibodies or lymphocytes already made by an animal or human donor. Vaccines are usually administered by injection (parenteral administration), but some are given orally. Vaccines applied to mucosal surfaces, such as those lining the gut or nasal passages, seem to stimulate a greater antibody response and may be the most-effective route of administration.

Vaccines and whole organism vaccines
This document discusses different types of vaccines, including whole organism vaccines. It begins by defining what a vaccine is and how it works to stimulate immunity. It then discusses the history of vaccines, including Edward Jenner's pioneering work developing the smallpox vaccine in 1798. The document outlines the two main types of whole organism vaccines - live attenuated vaccines, which use a weakened live version of the pathogen, and inactivated vaccines, which use killed forms of the microbe. Examples of each type are provided.
Vaccine
This document presents information about vaccines. It begins with a brief introduction defining a vaccine as a biological preparation that provides immunity against a disease. The history section then discusses how Edward Jenner developed the smallpox vaccine in 1796 and how Louis Pasteur later developed vaccines for chicken cholera and anthrax in the 1880s. The document goes on to describe the main types of vaccines as live attenuated, killed/inactivated, toxoid, subunit, conjugate, DNA, and recombinant vector vaccines. It also provides examples of diseases each vaccine type is used for and discusses their advantages and disadvantages.
Vaccine design and devolepment
Vaccines work by exposing the immune system to agents that resemble disease-causing pathogens, stimulating the body's immune response without causing illness. The document traces the history of vaccine development from Edward Jenner's smallpox vaccine in 1796 to current types including whole-organism, purified components, recombinant, DNA, and multivalent subunit vaccines. The long and complex process of developing a new vaccine can take 10-15 years and involves identifying the pathogen, developing animal models, conducting safety and efficacy trials, and addressing challenges like antigenic variation.
David Haselwood | How vaccines prevent diseases
David Haselwood - Vaccines provide immunity that protects you from disease without the risk of the infection. It contains a small amount of the germs or parts of the germs that cause disease. The germs in vaccines are either killed or weakened so they can't make you sick. Therefore, vaccination plays an important role in one’s health. #DavidHaselwood

Introduction to vaccines
This document provides an introduction to vaccines, including their principles, types, and examples. The main types discussed are inactivated/killed vaccines, live attenuated vaccines, toxoids, subunit vaccines, DNA vaccines, and recombinant live vaccines. Inactivated vaccines use killed disease-causing microbes, and stimulate a weak immune response but require boosters. Live attenuated vaccines use weakened live organisms to stimulate excellent lifelong immunity but rarely carry risk of disease if attenuation fails. Toxoids are made from inactivated toxins and cannot cause disease but may require adjuvants or boosters. DNA vaccines work by directly introducing genetic material that codes for antigens. They allow for rapid, low-cost production and generate therapeutic potential for chronic infections.
Vaccines
Vaccines provide active acquired immunity against diseases. They contain weakened or killed forms of microbes or their components that stimulate the immune system to recognize and destroy the microbe if encountered in the future. There are three main routes of administration: intradermal, oral, and intranasal. When administered, vaccines are phagocytosed by antigen presenting cells like dendritic cells, which activate T and B cells. Activated B cells become either antibody producing plasma cells or memory B cells. Common human vaccines include those for human papillomavirus, polio, measles, diabetes, hepatitis B, rabies, and various insulins.
Presentation immunization
Immunization involves deliberately inducing an adaptive immune response through vaccination. Vaccination uses killed or attenuated pathogens to provoke immunity without causing disease. The goals of vaccination are eradication and prevention of disease through complete or partial lifelong protection. Protection can be achieved through active immunization by administering live attenuated or inactivated pathogens/toxins/antigens, or through passive immunization by administering preformed antibodies. Effective immunization programs require assessing community needs, setting goals and strategies, estimating resources, and monitoring outcomes through delivery of vaccines at fixed sites, outreach, and mobile services.
Vaccine by Hamidul Kowsar
Vaccines are substances introduced into the body to prevent diseases caused by pathogens. They work by exposing the immune system to antigens without causing illness. There are two main types of vaccines - inactivated vaccines using killed pathogens and attenuated vaccines using weakened live pathogens. Some common examples are vaccines for hepatitis B, tuberculosis, anthrax, polio, typhoid, and smallpox. Vaccines are produced at large scales to administer to populations and the process involves inactivating or attenuating pathogens, purifying antigens, and mass production. While vaccines provide significant public health benefits, their large-scale production and distribution can also present challenges.

Vaccines work by exposing the immune system to molecules similar to those found in viruses and bacteria, training it to recognize and fight off future infections. As a result of vaccination programs led by WHO and UNICEF, global immunization rates have reached their highest levels ever, protecting millions of children from deadly diseases annually. While vaccines have essentially eradicated smallpox and brought many other illnesses under control, continued vaccination efforts are needed to defend against pneumonia, diarrhea, hepatitis and other leading causes of childhood mortality worldwide.

1. Vaccination involves administering an antigen to elicit an antibody response and protect against future infections. Jenner pioneered vaccination by inoculating cowpox to stimulate immunity against smallpox.
2. There are three main types of vaccines - those using dead or weakened pathogens, live attenuated pathogens, and purified components or antigens of pathogens. Recombinant hepatitis B vaccine uses the hepatitis B surface antigen protein produced in yeast cells.
3. Oral cholera vaccine is composed of an attenuated Vibrio cholerae strain genetically modified to delete the gene encoding the toxic A1 peptide of the cholera toxin. This renders the strain safe for use as a live vaccine.
Vaccination ppt
This document discusses different types of immunization and vaccination. It describes passive immunization, which provides immediate protection by injecting pre-formed antibodies, and active immunization, which activates the immune system to produce its own antibodies. Vaccines can be live attenuated, inactivated, toxoid, subunit, DNA, or recombinant vector-based. They are administered through various routes and involve primary vaccination and booster shots to maintain immunity. The document covers different vaccine-preventable diseases and periods of immunity conferred.
Bacterial vaccines
The document discusses different types of bacterial vaccines. It begins by introducing active and passive immunity. Active immunity is induced by vaccines made from bacteria or their products, while passive immunity provides preformed antibodies from another source. The main types of bacterial vaccines discussed are whole-organism attenuated or killed vaccines, purified macromolecule vaccines like polysaccharides or toxoids, and subunit vaccines. Specific examples provided include vaccines for cholera, plague, typhus, pertussis, tetanus, diphtheria, hepatitis B, and human papillomavirus. Memory cells and immunological memory play an important role depending on the incubation period of the pathogen.

Conjugate vaccines
Conjugate vaccines work by chemically linking a polysaccharide antigen from bacteria to a carrier protein or peptide. This elicits a stronger immune response compared to polysaccharide antigens alone. The first conjugate vaccine for Hib was developed in 1987 and significantly reduced Hib infection rates in children. Conjugate vaccines promote immunological memory by allowing the polysaccharide to be presented by MHC on antigen presenting cells to T cells. While more complex to produce, conjugate vaccines provide effective protection against encapsulated bacteria that ordinary vaccines cannot.
Microorganisms Vaccine And Antibiotics
Vaccines work by introducing a small, weakened amount of a virus or bacteria into the body to trigger an immune response and develop antibodies without causing illness. They are designed using different strategies depending on the pathogen, including weakening or inactivating viruses and neutralizing bacterial toxins. Antibiotics, meanwhile, are drugs that treat bacterial infections by killing or stopping the growth of bacteria.
Bacterial vaccines
There are several types of bacterial vaccines that work through different mechanisms of the immune system. Active immunization stimulates the body's own immune response by introducing an antigen from the bacteria. This induces long-term immunity through memory B and T cells. Passive immunization provides immediate, short-term protection by transferring pre-formed antibodies. Common bacterial vaccines include those targeting Streptococcus pneumoniae, Neisseria meningitidis, Haemophilus influenzae, diphtheria, tetanus, pertussis, Lyme disease, anthrax, tuberculosis, and typhoid fever. These vaccines contain inactivated toxins, purified proteins, capsular polysaccharides, or live attenuated bacterial strains.
Vaccines
Vaccines provide immunity to diseases and contain agents that stimulate the immune system. There are several types including whole organism vaccines using killed or attenuated microbes, purified components like toxoids and polysaccharides, recombinant and DNA vaccines. Vaccines work by inducing both antibody and cellular immune responses. While effective, they also carry small risks like adverse reactions that researchers continue working to understand and improve safety.
Vaccine production
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. 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.
Vaccines and its types
This document discusses different types of vaccines. There are three main types: whole organism vaccines, purified vaccines, and DNA vaccines. Whole organism vaccines use weakened or killed pathogens and can be attenuated (like measles and polio vaccines) or inactivated. Purified vaccines use isolated components of pathogens like capsular polysaccharides or toxins. DNA vaccines introduce DNA sequences that cause the body to produce antigens and activate an immune response. The document provides examples and details on each type of vaccine.
Vaccine
Vaccines work by exposing the immune system to antigens from pathogens. This stimulates the body to develop immunity against future infections from those pathogens. Edward Jenner developed the first vaccine for smallpox in 1796 by using cowpox to provide protection against smallpox. There are several types of vaccines including live attenuated, inactivated, subunit, toxoid, conjugate, DNA, and recombinant vector vaccines. Vaccines must go through multiple stages of testing before being approved for public use to ensure they are safe and effective. An ideal vaccine would provide long-lasting immunity after a single dose with a strong safety profile.
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.

The stages of vaccine development and regulation are outlined. Ideal characteristics of vaccines and causes of mortality in children are also summarized.
Vaccines.pptx
Vaccines provide immunity against diseases by inducing antibody formation when a suspension of weakened or dead microorganisms is introduced to the body. The concept of immunity began with the observation that people who recovered from plague could resist it again. Variolation involved infecting people deliberately with smallpox to produce immunity. Edward Jenner developed the smallpox vaccine using cowpox fluid and demonstrated that inoculation led to immunity. Louis Pasteur coined the term "vaccine" and developed vaccines for rabies and other animal diseases. Vaccines are classified as attenuated, inactivated, toxoids, subunits, conjugates, or nucleic acid depending on their composition and method of production.
Immunization
The document defines key terms related to immunization and vaccination. It explains that vaccination is a process where a person is protected against a disease through administration of a vaccine, which stimulates their immune system to produce immunity. A vaccine contains a weakened or inactivated form of a pathogen that allows the body to develop immunity without causing disease. The document then reviews the history of vaccines, noting that Edward Jenner in 1796 demonstrated that inoculation with cowpox provided protection against smallpox.
Immunity and vaccine technology
Vaccines provide protective immunity and immunological memory to individuals, families and communities against any infectious disease.
Vaccines are cheap, cost – effective , easily administered and adaptable to mass vaccination.
Viral diseases can be managed through vaccination.
Newer vaccines
Vaccines provide immunity to diseases by exposing the immune system to agents that resemble disease-causing pathogens. The first vaccine was developed by Edward Jenner in 1796 to prevent smallpox. Since then, vaccines have been created to protect against many additional diseases. Newer vaccines continue to be developed using technologies like recombinant DNA. Vaccines are necessary public health tools that help prevent disease outbreaks in a cost-effective manner.
Vaccines
Vaccines stimulate the body's immune response by introducing a substance to produce protection against a disease-causing pathogen. Vaccines contain live but weakened forms of the germs that cause disease or parts of the germs. Edward Jenner demonstrated in 1798 that infection with cowpox could protect against smallpox in humans, laying the foundation for vaccination. Today, vaccines are administered through injection, orally, or intranasally and help prevent diseases like measles, diphtheria, and pertussis. They work by exposing the immune system to antigens, stimulating antibody production and conferring future protection against infection.

It explains that vaccines induce immunity by triggering an antibody response to antigens from weakened or killed disease-causing microorganisms. Vaccines are produced using live attenuated microbes, inactivated pathogens, recombinant DNA technology, or as mixtures targeting multiple diseases. Large-scale production involves growing microbes, inactivating or attenuating them, and adding stabilizers or adjuvants to the purified antigen formulations.
INTRODUCTION TO IMMUNIZATION
This document provides an introduction to immunization. It discusses the history of immunization beginning with Edward Jenner's smallpox vaccine in 1796. It describes active immunization which involves administration of antigens to induce an immune response, and passive immunization which involves transfer of pre-formed antibodies. Common childhood vaccines and booster shots are listed. Benefits of immunization include disease protection while risks include mild side effects. Various antibody-antigen tests used in immunology are also summarized such as precipitation, agglutination, neutralization, and ELISA tests.

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.
Vaccine converted
- Vaccines work by exposing the immune system to antigens from pathogens, stimulating the body's immune response without causing illness. There are several types of vaccines including live attenuated, inactivated, toxoids, subunit/conjugate, and recombinant/DNA vaccines.
- Edward Jenner is considered the founder of vaccinology for his work developing the smallpox vaccine in 1796. Louis Pasteur later developed vaccines through attenuating pathogens and the term vaccine comes from his work with the cowpox virus.
- Vaccine development involves pre-clinical testing in labs and animals followed by four phases of clinical trials to assess safety, immunogenicity, and efficacy in humans. The goal is to license an effective
VACCINES
- The document summarizes the history and development of vaccines from early variolation techniques to modern vaccines. It discusses the different types of vaccines including attenuated, inactivated, recombinant subunit, toxoid, and conjugate vaccines. It provides examples of each vaccine type and describes how vaccines work to produce immunity through initiating an immune response to antigens without causing disease. The summary concludes by emphasizing the importance of vaccination for protection against disease.

Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Heat killed vaccine
- 2. Vaccine The term vaccine is derived from the Latin word, vacca (meaning cow), because cowpox was used to prevent smallpox. Vaccination is the deliberate attempt to prevent disease by “teaching” the immune system to employ acquired immune mechanisms. In the 21st century, vaccines are also being used to enhance existing immune mechanisms with the development of vaccines as treatments, so-called therapeutic vaccination.
- 3. History The first vaccine was introduced by British physician Edward Jenner, who in 1796 used the cowpox virus (vaccinia) to confer protection against smallpox, a related virus, in humans.
- 4. Killed / Inactivated Vaccine • Inactivated vaccines are those that contain organisms that have been killed or inactivated with heat or chemicals. Inactivated vaccines elicit an immune response, but the response often is less complete than with attenuated vaccines. Because inactivated vaccines are not as effective at fighting infection as those made from attenuated microorganisms, greater quantities of inactivated vaccines are administered. Vaccines against rabies, polio (the Salk vaccine), some forms of influenza, and cholera are made from inactivated microorganisms.
- 6. Adverse reactions associated with inactivated whole-cell vaccines
