Vaccine A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.ome vaccination critics say that vaccines are ineffective against disease or that vaccine safety studies are inadequate. Some religious groups do not allow vaccination, and some political groups oppose mandatory vaccination on the grounds of individual liberty.

Cancer Vaccines Vaccines are medicines that boost the immune system's natural ability to protect the body against “foreign invaders,” mainly infectious agents, that may cause disease. The immune system is a complex network of organs, tissues, and specialized cells that act collectively to defend the body.ancer preventive vaccines target infectious agents that cause or contribute to the development of cancer (8). They are similar to traditional vaccines, which help prevent infectious diseases, such as measles or polio, by protecting the body against infection.

- Understanding the difference between vaccines, vaccinations, and immunizations can be tricky. Below is an easy guide that explains how these terms are used: A vaccine is a product that produces immunity from a disease and can be administered through needle injections, by mouth, or by aerosol. A vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism.

Description and Brand Names 3. Meningococcal vaccine is an active immunizing agent used to prevent infection cause by certain groups of meningococcal bacteria. Meningococcal infection can cause life-threatening illnesses such as meningitis and bacteremia. Meningococcal is also one of the recommended childhood immunizations.

What is the flu (influenza)? The flu shot is an inactivated vaccine (containing killed virus) that's given with a needle, usually in the arm. This season's vaccine protects against the three influenza viruses that research indicates will be most common during the season. This includes an influenza A (H1N1) virus, an influenza A (H3N2) virus, and an influenza B virus. The vaccine takes effect approximately two weeks after it has been administered as antibodies (substances in the blood that protect against infection) accumulate and provide protection against influenza.

Types of Vaccines Here are the main types of vaccines: Live Attenuated Vaccines: These vaccines are made up of living virus or bacteria that have been weakened (attenuated) by scientists. These vaccines are very effective, but in rare cases (such as in people with compromised immune systems), can cause infection.

Vaccines (immunizations) - overview Four types of vaccines are currently available: 1  Live virus vaccines use the weakened (attenuated) form of the virus. 2  The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples.

Live Vaccines and Vaccine Shedding Live vaccines contain a weakened or attenuated form of a virus or bacteria. They are altered so that they can't cause disease. The other main type of vaccine is made of the inactivated virus or bacteria (whole vaccine) or just parts of the virus or bacteria (fractional vaccine).

Vaccine A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.he terms vaccine and vaccination are derived from Variolae vaccinae (smallpox of the cow), the term devised by Edward Jenner to denote cowpox.

Chickenpox (Varicella) Vaccine The chickenpox vaccine is a shot that can protect nearly anyone who receives the vaccine from catching chickenpox. It's also called the varicella vaccine, because chickenpox is caused by the varicella-zoster virus. The vaccine is made from a live but weakened, or attenuated, virus.efore the varicella vaccine was licensed in the U.S. in 1995, there were approximately 100 deaths and more than 11,000 hospitalizations a year from chickenpox.

Description and Brand Names Meningococcal vaccine is an active immunizing agent used to prevent infection by certain groups of meningococcal bacteria. The vaccine works by causing your body to produce its own protection (antibodies) against the disease. Menomune® is active against groups A, C, Y and W-135 meningococcal bacteria only. Bexsero® and Trumenba® is active against group B meningococcal bacteria only.

- Vaccines create immunity that protects you from an infection without causing the suffering of the disease itself. Sometimes vaccines are called immunizations, needles or shots. Here's how vaccines work: 1  Most vaccines contain a little bit of a disease germ that is weak or dead.

- 1 Live virus vaccines use the weakened (attenuated) form of the virus. The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples.  Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria. The flu vaccine is an example.

2. What is in a vaccine? Vaccines contain antigens and adjuvants. Vaccines generally have two major types of ingredients, antigens and adjuvants. Antigens are designed to cause the immune system to produce antibodies and/or T-cells against a specific pathogen or its toxin. Adjuvants amplify immune responses more generally.

- Types of vaccines. Some vaccines are prophylactic and are used to prevent or ameliorate the effects of a future infection by any natural or wild pathogen. Some vaccines however may also be therapeutic for example cancer vaccines that are being developed against cancer.

Making The Vaccine Decision Vaccines contain ingredients, called antigens, which cause the body to develop immunity. Vaccines also contain very small amounts of other ingredients--all of which play necessary roles either in making the vaccine, or in ensuring that the vaccine is safe and effective. These types of ingredients are listed below.

Vaccines for Children - A Guide for Parents and Caregivers Vaccines have contributed to a significant reduction in many childhood infectious diseases, such as diphtheria, measles, and Haemophilus influenzae type b (Hib). Some infectious diseases, such as polio and smallpox, have been eliminated in the United States due to effective vaccines.accines work by preparing the body’s immune system for future attacks by a certain disease, caused by either viruses or bacteria. Vaccines contain weakened bacteria or viruses, or parts of bacteria or viruses, and mimic these disease-causing agents (which are called antigens).

Types of Vaccines Types of Vaccines. There are many types of vaccines, but all generally work by teaching the immune system to recognize and eliminate a disease-causing microorganism. Some vaccines are designed to help the immune system prevent an infection and are called preventive vaccines.

Dtp Vaccine What are the DTP DtaP vaccines? DTP and DTaP vaccines are a shot of medicine that help protect your child from the diseases diphtheria (dip-theer-e-uh), tetanus (tet-nuss), and pertussis (per-tuh-sis). These 3 diseases were very common before vaccines were found and caused many deaths every year.

Definition of Terms Immunity: Protection from an infectious disease. If you are immune to a disease, you can be exposed to it without becoming infected. Vaccine: A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease. Vaccines are usually administered through needle injections, but can also be administered by mouth or sprayed into the nose.

Vaccine Types When the immune system receives a vaccine containing a harmless toxoid, it learns how to fight off the natural toxin. The immune system produces antibodies that lock onto and block the toxin. Vaccines against diphtheria and tetanus are examples of toxoid vaccines.
