Pneumococcal conjugate vaccine Pneumococcal conjugate vaccine is a pneumococcal vaccine and a conjugate vaccine used to protect infants, young children, and adults against disease caused by the bacterium Streptococcus pneumoniae. There are currently three types of PCV available on the global market, which go by the brand names: Prevnar, Synflorix and Prevnar 13. Prevnar is a heptavalent vaccine, meaning that it contains the cell capsule sugars of seven serotypes of the bacteria S. pneumoniae, conjugated with diphtheria protei

- Each vaccine contains a killed or weakened form of the organism (usually a virus or bacterium) that causes a particular disease. Even though the organism in the vaccine has been altered so that it won’t make you ill, the part of the organism that stimulates your immune system to respond (the antigen) is still present.

- The conjugate pneumococcal vaccine protects children against invasive pneumococcal infections such as pneumonia, bacteraemia (infection of the blood) and meningitis (infection of the brain). IPD is a bacterial infection caused by a type of bacteria called streptococcus pneumoniae (or pneumococcus).

How Do Vaccines Work? Vaccines are like a training course for the immune system. They prepare the body to fight disease without exposing it to disease symptoms. When foreign invaders such as bacteria or viruses enter the body, immune cells called lymphocytes respond by producing antibodies, which are protein molecules.

- Each vaccine contains a killed or weakened form of the organism (usually a virus or bacterium) that causes a particular disease. Even though the organism in the vaccine has been altered so that it won’t make you ill, the part of the organism that stimulates your immune system to respond (the antigen) is still present.n antigen specifically induces the production of antibodies which can bind to it and neutralise it. While most vaccines work by inducing B lymphocytes to produce antibodies (see below), activation of T-cells — another type of immune system cell that helps protect against disease — is also important for some vaccines.

What are Subunit Vaccines? Since only a few components are included in the vaccine ability to target the vaccines at the site where immunity is required is possible. Examples of purified subunit vaccines include the HA vaccines for influenza A and B, and hepatitis B surface antigens (HBs Ags) derived from the plasma of carriers. (1) The disadvantage of subunit vaccines is that they generally require strong adjuvants and these adjuvants often induce tissue reactions.

Adjuvants and Ingredients Adjuvants & Ingredients. Adjuvants are substances added to certain vaccines to increase the body's immune response to that vaccine. Ingredients are added to inactivate viruses or bacteria, to preserve them, and to prevent them from losing potency over time. Vaccines containing adjuvants and ingredients are tested for safety in clinical trials before they are licensed for use in the United States. Adjuvants and Ingredients Resources.

Squalene: The Swine Flu Vaccineâs Dirty Little Secret Exposed Why Vaccinations Can Be so Dangerous. The presumed intent of a vaccination is to help you build immunity to potentially harmful organisms that cause illness and disease. However, your body's immune system is already designed to do this in response to organisms that invade your body naturally. Most disease-causing organisms enter your body through the mucous membranes of your nose, mouth, pulmonary system or your digestive tract – NOT through an injection.

- Saving time is important to prevent a pathogen from establishing itself and infecting more cells in the body. An effective vaccine will optimally activate both the innate and adaptive response. An immunogen is used to activate the adaptive immune response so that specific memory cells are generated.

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.

Adjuvant An adjuvant can also act as an irritant, which engages and amplifies the body's immune response. A tetanus, diphtheria, and pertussis vaccine, for example, contains minute quantities of toxins produced by each of the target bacteria, but also contains some aluminium hydroxide.

Meningococcal Vaccination Meningococcal group C (MenC) conjugate vaccine is part of the combined Hib and MenC conjugate vaccine given between 12 and 13 months and MenACWY (replacing MenC booster) at around 14 years. Men B vaccine is now also part of the primary immunisation programme, given with the infant's first and third routine vaccinations (at 2 months and 4 months of age) and a booster given between 12 and 13 months.

Why Immunize Your Child A: Children with certain health problems may need to avoid some vaccines or get them later. In most cases, children with cancer, those taking oral or injected steroids for lung or kidney conditions, or those who have problems with their immune systems should not get vaccines that are made with live viruses. To protect these children it is very important for others to be vaccinated. For children with a recent history of nerve disorders, the pertussis part of the DTaP vaccine may need to be delayed.

Scientists Learn How Flu Virus Changes So Quickly TUESDAY, Oct. 3, 2017 (HealthDay News) -- Scientists have pinpointed a mechanism that helps flu viruses mutate rapidly, which could lead to new ways to fight the flu. Because flu viruses mutate quickly, flu vaccines have to be redesigned every year. The MIT researchers found that to mutate rapidly, flu viruses use a group of proteins called chaperones in infected cells in the host (a person or animal with the flu). Blocking flu viruses from using the host cells' chaperones could help prevent the viruses from developing resistance to existing drugs and vaccines, the study authors said.

Fact or Fiction?: Vaccines Are Dangerous When a person encounters a pathogen, there is no way to predict whether it will induce a mild or severe form of disease or how the body will react. But vaccines are selected to contain a weakened or dead form of the disease-causing germ that can spark an immune response. Exposure will thus allow the body to build up immunity in a controlled way. The immune system reaction stops this compromised foreign invader in its tracks at the site of injection.

Making The Vaccine Decision Vaccines help develop immunity by imitating an infection, but this “imitation” infection does not cause illness. Instead it causes the immune system to develop the same response as it does to a real infection so the body can recognize and fight the vaccine-preventable disease in the future.
