Vaccines (immunizations) - overview Four types of vaccines are currently available: 1  Live virus vaccines use the weakened (attenuated) form of the virus. 2  Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria.  Toxoid vaccines contain a toxin or chemical made by the bacteria or virus.

- There are currently two types of pneumococcal vaccines: pneumococcal conjugate vaccine (PCV13) and pneumococcal polysaccharide vaccine (PPSV23). There are more than 90 types of pneumococcal bacteria. PCV13 protects against 13 types and PPSV23 protects against 23 types.

Types of immunizations Immunization can occur in one of two forms. Types of immunizations Immunization can occur in one of two forms. Active immunization involves stimulating the immune system to produce antibodies to fight a disease. This is the form of immunization used in creating vaccines.Passive immunization involves providing an antibody to the patient.It provides only temporary protection against disease.iphtheria, tetanus and pertussis vaccine (DTaP). Protects against diphtheria (serious throat infection), tetanus (severe nerve disease) and pertussis (respiratory illness sometimes known as “whooping cough”). DTaP is provided in a series of five injections from ages 2 months to 6 years.

- 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.

Vaccine They may produce a mild or subclinical form of the disease. Attenuated vaccines include those for measles, mumps, polio (the Sabin vaccine), rubella, and tuberculosis. Inactivated vaccines are those that contain organisms that have been killed or inactivated with heat or chemicals.

- 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.

- Types of vaccines. The way in which the body responds to a vaccine depends on the type of vaccine being administered. There are several different types of vaccine available and with new technology there will be further additions.lthough live attenuated vaccines replicate, they usually do not cause disease, such as may occur with the natural (“wild”) organism. When a live attenuated vaccine does cause “disease,” it is usually much milder than the natural disease, and is referred to as an adverse reaction.

Flu Vaccine The best means of preventing the flu is getting an influenza vaccination. The CDC recommends an annual flu vaccine for everyone 6 months of age and older. Two general types of vaccines are available. One is the injectable vaccine (known as the flu shot) made from inactivated virus. The flu shot contains only killed influenza viruses A and B.

Pneumococcal vaccine Pneumococcal vaccines are vaccines against the bacteria Streptococcus pneumoniae. Their use can prevent some cases of pneumonia, meningitis, and sepsis. There are two types of pneumococcal vaccines: conjugate vaccines and polysaccharide vaccines. They are given either by injection into a muscle or just under the skin. The World Health Organization recommends the use of the conjugate vaccine in the routine immunizations given to children.

- Typhoid vaccines are vaccines developed to prevent typhoid fever. There are two effective types available: 1  Ty21a, which is a live vaccine given orally. 2  Vi capsular polysaccharide vaccine, which is an injectable subunit vaccine.oosters are recommended every 5 years. The Vi capsular polysaccharide vaccine is licensed for use from age two years and older, and boosters are required every three years.

- There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used. Live attenuated vaccines are produced by modifying a disease-producing (“wild”) virus or bacteria in a laboratory.lthough live attenuated vaccines replicate, they usually do not cause disease, such as may occur with the natural (“wild”) organism. When a live attenuated vaccine does cause “disease,” it is usually much milder than the natural disease, and is referred to as an adverse reaction.

Flu Vaccine (Influenza Immunization or Flu Shot) Types of influenza (flu) vaccines include the injection (killed virus) and nasal spray vaccines (containing live but weakened virus). Each year, influenza viruses change slightly, making the vaccine used in previous years ineffective.

The Flu And The Vaccine The most common flu vaccine is the inactivated influenza vaccine which is prepared from the fluids of chick embryos inoculated with a specific type(s) of influenza virus. The strains of flu virus in the vaccine are inactivated with formaldehyde and preserved with Thimerosal, which is a mercury derivative.

A Look at Each Vaccine: Pneumococcal Vaccine A second type of pneumococcal vaccine, known as the pneumococcal polysaccharide vaccine, protects against more types of pneumococcus (23 types), but does not include the harmless protein, so it is mostly used only in older adults or those at higher risk for pneumococcus.

What Is Polio? There are two types of vaccine that can prevent polio: inactivated poliovirus vaccine (IPV) and oral poliovirus vaccine (OPV). Only IPV has been used in the United States since 2000; OPV is still used throughout much of the world.

Cancer Vaccines Cancer vaccines belong to a class of substances known as biological response modifiers. Biological response modifiers work by stimulating or restoring the immune system’s ability to fight infections and disease. There are two broad types of cancer vaccines: 1  Preventive (or prophylactic) vaccines, which are intended to prevent cancer from developing in healthy people. 2  Treatment (or therapeutic) vaccines, which are intended to treat an existing cancer by strengthening the body’s natural immune response against the cancer (9).

Vaccine Clinic Both vaccines can prevent 4 types of meningococcal disease, including 2 of the 3 types most common in the United States and a type that causes epidemics in Africa.

- Different types of vaccines. Most vaccines are injected, but some can be given as a liquid that is swallowed. There are 4 main types of vaccines: 1  live attenuated vaccines, which contain a living, but weakened, form of the germ (organism); 2  inactivated vaccines, which contain a killed form of the organism;

- Another way to produce active immunity is by vaccination. Vaccines interact with the immune system and often. produce an immune response similar to that produced by. the natural infection, but they do not subject the recipient to. the disease and its potential complications.lassification of Vaccines There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used.

The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used.Live attenuated vaccines are produced by modifying a disease-producing (“wild”) virus or bacteria in a laboratory.n order to produce an immune response, live attenuated vaccines must replicate (grow) in the vaccinated person. A relatively small dose of virus or bacteria is given, which replicates in the body and creates enough virus/bacteria to stimulate an immune response.

Polio vaccine Polio vaccines are vaccines used to prevent poliomyelitis. There are two types: one that uses inactivated poliovirus and is given by injection, and one that uses weakened poliovirus and is given by mouth. The World Health Organization recommends all children be fully vaccinated against polio. The two vaccines have eliminated polio from most of the world, and reduced the number of cases reported each year from an estimated 350,000 in 1988 to 37 in 2016. The inactivated polio vaccines are very saf
