A subunit vaccine is a vaccine that contains purified parts of the pathogen that are antigenic, or necessary to elicit a protective immune response. [ 1 ] [ 2 ] Subunit vaccine can be made from dissembled viral particles in cell culture or recombinant DNA expression, [ 3 ] in which case it is a recombinant subunit vaccine .
A conjugate vaccine is a type of subunit vaccine which combines a weak antigen with a strong antigen as a carrier so that the immune system has a stronger response to the weak antigen. Vaccines are used to prevent diseases by invoking an immune response to an antigen, part of a bacterium or virus that the immune system recognizes. [ 2 ]
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease. [1] [2] ...
An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). [1] Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. [2] These vaccines contrast to those produced by "killing" the pathogen ...

The vaccines do not have any biological contamination since they are chemically synthesized. The vaccines are water-soluble and can be kept stable under simple conditions. The peptides can be specially designed for specificity. A single peptide vaccine can be designed to have multiple epitopes to generate immune responses for several diseases.
A synthetic vaccine is a vaccine consisting mainly of synthetic peptides, carbohydrates, or antigens. They are usually considered to be safer than vaccines from bacterial cultures. Creating vaccines synthetically has the ability to increase the speed of production. This is especially important in the event of a pandemic.
The DPT vaccine or DTP vaccine is a class of combination vaccines to protect against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus (lockjaw). [7] The vaccine components include diphtheria and tetanus toxoids , and either killed whole cells of the bacterium that causes pertussis or pertussis antigens .
