Available vaccines

Methods, regulations and indications for vaccination.

Vaccines are produced in different ways, but all of the components found in common viruses or bacteria are present: these are substances (antigens) that can be recognised by our immune system and that stimulate our body’s natural defence mechanisms.

The process that leads to the birth, validation and subsequent production of a vaccine, is extraordinarily complex and thorough. This topic is dealt with concisely in the introductory articles.

The remainder of the section describes the general requirements for each vaccine listed.
