Subunit vaccine - Wikipedia
WEBA 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.

WEBDec 22, 2022 · Subunit, recombinant, polysaccharide, and conjugate vaccines use specific pieces of the germ—like its protein, sugar, or capsid (a casing around the germ). Because these vaccines use only specific pieces of the germ, they give a very strong immune response that’s targeted to key parts of the germ.

WEBJul 29, 2020 · A subunit vaccine is a genome-free vaccine that consists of single or multiple viral proteins, which can confer immunoprotection in the absence of viral genetic material. In general, subunit vaccines for EBOV are divided into two forms: classical subunit vaccines and VLPs.
Different types of COVID-19 vaccines: How they work
WEBSubunit vaccines include only the parts of a virus that best stimulate your immune system. This type of COVID-19 vaccine contains harmless S proteins. Once your immune system recognizes the S proteins, it creates antibodies and defensive white blood cells.
