Polysaccharide vaccines use sugar molecules (known as polysaccharides) from the outer layer of a bacteria or virus. Theses virions are approximately 40 nm in diameter, which are known as one of the smallest enveloped animal viruses. Unauthorized use of these marks is strictly prohibited. Some of the advantages of Ad vaccines include their lack of pathogenicity in humans, especially for replication-deficient mutants, [ 57] oral or nasal administration, which promotes mucosal. Once injected into the body, the DNA for the germ is reproduced by the body and is recognized by the immune system. Low risk if properly inactivated Disadvantages: Not work for all viruses as antigenicity may loss during denaturation (such as measles). Front Immunol. For example, to make the hepatitis B vaccine, part of the DNA from the hepatitis B virus is . For decades flu vaccines have been produced by growing flu viruses in eggs, which is required for egg-based vaccine production. More information is available at How Influenza (Flu) Vaccines Are Made. These weak antigen coats are linked to a stronger carrier protein using chemicals, and this combination of the weak antigen coat and stronger carrier proteins triggers the immune system to act more aggressively against the weak antigen.
