Vaccines are produced in large scale as they need to be administered to large populations of children and adults to be effective as a public health tool. This large scale production is often a challenge. Vaccine production has several stages. Process of vaccine manufacture has the following steps: Inactivation - This involves making of the antigen preparation Purification - The isolated antigen is purified Formulation - The purified antigen is combined with adjuvants, stabilizers and preservatives to form the final vaccine preparation.

There are different kinds of triple antigen vaccines. A triple antigen vaccine is one made with three different antigens (often three virus strains). The seasonal flu vaccines are examples of triple antigen vaccines, because they contain vaccines against the three influenza viruses most prominent and most likely to spread that season. These are also called Triple Valent or Trivalent vaccines. Another example is the MMR trivalent vaccine made to vaccinate against Measles, Mumps, and Rubella. Several of the childhood vaccinations are this type of trivalent vaccine.
adjuvants are substances that when mixed with isolated antigen,increases its immunogenicity,thereby provoking inflammation and draws large number numbers of immune system cells to the site of injection.

An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
At present, there is no cure for Hepatitis B. There is a vaccine that will prevent it, however.
Its the antigen in a particular foreign body or pathogen that the body recognizes as "allo" or unfamiliar.. Maybe even harmful. So antibodies are produced against these antigens. And since they are 'neutralizing antibodies' it follows that the antigens they bind to are 'neutralizing antigens'
An example of active immunity is the oral polio vaccine because it's a live attenuated vaccine. It means that, weakened polio virus will be given to you so that your body can form antibodies from it and can fight the virus. If your body itself made the antibody from an antigen, it's an example of an active immunity.
An adjuvant is a special binding substance that enhances immunogenicity and prolongs antigen retention at the injection site. It helps to stimulate a stronger immune response by promoting the activation of immune cells and improving the overall effectiveness of a vaccine.
Antigens.
A substance that contains the antigen of a pathogen is known as a vaccine. Vaccines are designed to stimulate the immune system by introducing a harmless form or component of the pathogen, such as proteins or inactivated viruses. This exposure helps the body recognize and mount an immune response against the pathogen if encountered in the future, providing immunity.
