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.

Many modern vaccines are made of only the parts of the pathogen necessary to invoke an immune response (a subunit vaccine) – for example just the surface proteins of the virus, or only the polysaccharide coating of a bacterium. Some vaccines invoke an immune response against the toxin produced by bacteria, rather than the bacteria itself.
The vaccine is given as an intradermal injection using a spring-powered jet injector. [2] [3] This is because successful transfection of DNA vaccines requires traveling across both the cell plasma membrane and the nuclear membrane, [4] and using a conventional needle gives poor results and leads to low immunogenicity. [4] [5]
Vaccines are complex mixtures of biological compounds, and unlike the case for prescription drugs, there are no true generic vaccines. The vaccine produced by a new facility must undergo complete clinical testing for safety and efficacy by the manufacturer. For most vaccines, specific processes in technology are patented.
ACAM2000 is a vaccine developed by Acambis, which was acquired by Sanofi Pasteur in 2008, before selling the smallpox vaccine to Emergent Biosolutions in 2017. Six strains of vaccinia were isolated from 3,000 doses of Dryvax and found to exhibit significant variation in virulence.
The FDA has granted 510(k) clearance to Abiomed Inc's (NASDAQ: ABMD) Impella Low Profile Sheath. Compared to the existing 14 French (Fr) sheath used for the placement of Impella CP, the new sheath ...
Nicotine vaccines are immunogens made up of synthetic drug haptens connected to immunogenic carriers, which are then packaged in adjuvants to boost immunogenicity. [4] The conjugate vaccine produces a strong immunogenic response from the body by stimulating the production of antibodies , which is administered through a vaccination .
