Types of Vaccines

Classified by usage.

Injection molding


Classified according to the nature of the antigen.

Killed Vaccine

Live Attenuated Vaccine

Killed Vaccine

May be divided into

Whole cell vaccine, such as thiamine vaccine. Cholera vaccine And rabies vaccines

Subunit vaccines are used to make vaccines, such as the production of antigen by direct microbial extract such as Plasma-derived hepatitis B vaccine.

Antigen production by recombinant DNA technology such as Yeast-derived hepatitis B vaccine

Synthetic peptide synthetic vaccine

Killed whole cell-subunit vaccine, such as Oral B subunit-whole cell cholera vaccine

Toxoid is produced from toxins of bacteria such as tetanus toxoid and toxoid diphtheria.

Anti-idiotypic vaccination by injection of antigen to induce antibody production. Then antibody (Ab1) is injected into animals again. Experimental animals will be created. An anti-idiotypic antibody (Ab2) is an internal image that mimics an antigen-mimic to produce a vaccine that can stimulate immunity to the original pathogen. This vaccine is in the experimental stage.

A nucleic acid vaccine is currently being studied in animals. The DNA contains a gene that controls the production of proteins that stimulate the protective antibody injected into the host cell to produce the desired protein in the body and to stimulate the antigen. Immune disease. In animal studies, nucleic acid vaccines can be introduced into the host in a number of ways, such as bringing DNA to coat on small gold particles and firing into skin cells using a special DNA gun, or perhaps by linking DNA to fat. Called cationic lipids into the host by spraying aerosol through the nose or throat.

Currently, there are researchers on the development of vaccines in the form of fruits and vegetables. This will give the vaccine. By oral immunization using genetic engineering techniques and plant diseases such as tobacco and potato plants. Fruit and vegetables with protein antigen can stimulate immunity to that disease. Vaccines that are highly probable to be tested include hepatitis B vaccine and cholera vaccine.

Live attenuated vaccine

All vaccines are whole cell vaccine produced by natural microorganisms. The action to cause the disease to weaken or reduce the severity. It can stimulate the bodys immune system. How to make microorganisms weak.

The culture continues until the microorganism.

To treat microorganisms with certain chemicals.

UV treat

Use of recombinant DNA technology. Genetic transformation of microorganisms.

Currently, live antituberculosis vaccines are produced in the form of a hybrid vaccine by expressing the antigen of a particular type of microorganism. In other microorganisms, which are weak. Bring the microorganisms to the genes to produce vaccines. When vaccines enter the body, they will create an antigen that is regulated by the gene that promotes immunity to the host cell.
