Generic Vaqta

As a type of "biologic" medicine, Vaqta is made using living cells and is classified under a different set of regulations than most other prescription drugs. These laws currently prevent any generic biologic products, including Vaqta, from being manufactured. However, these laws are starting to change, and a company may be able to eventually make a generic Vaqta product.

Is a Generic Version of Vaqta Available?

Vaqta® (hepatitis A vaccine) is a hepatitis A vaccine. It is approved for use in adults, adolescents, and children as young as 12 months old. Vaqta is given as two doses, with 6 to 18 months between each dose.
Vaqta is made by Merck & Co., Inc. There are no generic versions of Vaqta currently available. Other hepatitis A vaccines are available, but they are actually different brand-name products; none of them are a generic for Vaqta.
Vaqta is a "biologic" medication and is therefore under different rules and regulations than most other prescription medications. In the past, biologic products were largely protected from generic competition. However, regulations are changing to allow manufacturers to make generic versions of biologics.

What Are Biologics?

Biologics are medications made from living cells or organisms. These are used to produce complex proteins or molecules, which are then used to make medical products, such as medicines, vaccines, or blood products.
Because biologics are made with living cells, rather than chemically created like most other prescription medicines, it is not possible for a generic manufacturer to make an identical version of a brand-name biologic product already on the market. Therefore, generic biologics are sometimes called "biosimilars" or "follow-on biologics." Biosimilars are products that are similar enough to a brand-name biologic to have the same effects in the body.
