Vaccines, which are used to elicit an immune response, are an excellent example of antigens. Antibodies are generated or engineered to interact with antigens based on the antibody’s complementary deciding region (figure 1.2). The humoral system or antibody-mediated beta cellular immunity involves macromolecules in extracellular fluids—antibodies, complement proteins, and antimicrobial peptides (‘humor’ refers to body fluids). Humoral immunity involves antibodies, the activation of cytokines, isotype switching, germinal center formation, cell generation, and affinity maturation. Additionally, it includes the effector function of antibodies, including toxic and pathogen neutralization, opsonin promotion of phagocytosis, and complement activation.

Both originator and biosimilar biopharmaceuticals must, however, have equivalent safety and clinical performance throughout their lifecycle. Modern analytical instruments monitor process variations and define a particular design space for each biologic (e.g. liquid chromatography, immunoassays, mass spectrometry, etc). Biosimilars, unlike small-molecule generics, require a different regulatory framework requiring more intensive testing than needed for small-molecule generics, yet less than for a new biological product.
Biotechnology or other methods may be used to create the production process. In addition, products can be made using more traditional approaches, such as blood or plasma-derived products and various vaccines. Antibodies produced by a single cell are called monoclonal antibodies. These antibodies are similar to those used by the human immune system to combat bacteria and viruses. However, because they are ‘suitable’, they can be used to neutralize or obstruct any specific substance or cell type . An engineered entity means an entity whose DNA structure has been modified using recombination technology.

Of course not everyone may share the same commitment to safety, so it’s important to communicate your expectations clearly so that you and your date are on the same page. Single parents need special places to date, like Stirand EliteSingles, where users understand each other’s unique requirements and dilemmas. Individuals may look very different in person than they do online, so be prepared for the preferences to change. Finally, contact a buddy before the date to inform them of the whereabouts and anticipated return time. To provide an extra layer of protection, request that they call or text during the date to ensure maximum safety.

Insulin comprises a short chain of 51 amino acids discovered in the 1940s in the same way that many biologics were—by extracting it from animals—hence the word ‘natural source’. Despite its similarities to other biologics, the FDA regulated insulin as a drug rather than a biologic until March 2020. Under the FFDCA some of these products were regulated as medicines (e.g. insulin and human growth hormone created using recombinant DNA technology). In contrast, others were regulated as biologics under the PHSA (e.g. cytokines, proteins involved in the immune response, and blood factors). Biologics licensed under the FFDCA will be considered licenses under the PHSA as of 23 March 2020.
