Supemtek (Quadrivalent Recombinant Influenze Vaccine)

What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

    Description

    SupemtekĀ® is a quadrivalent recombinant influenza vaccine developed by Sanofi Pasteur. It is designed to provide active immunization against influenza caused by two influenza A virus subtypes (H1N1 and H3N2) and two influenza B virus lineages (Victoria and Yamagata). Unlike traditional egg-based vaccines, SupemtekĀ® is produced using recombinant DNA technology in an insect cell line, allowing for an exact genetic match to the World Health Organization (WHO) recommended strains . This method eliminates the risk of egg-adapted mutations, potentially enhancing vaccine effectiveness.
