The immune system is responsible for self-regulating, defending and protecting the human body from all kinds of external aggressions (viruses, bacteria, moulds, harmful agents, etc.), recognising any foreign elements (antigens), and triggering an immune response.

Infection is the process whereby a germ or infectious agent invades and remains in the body, multiplying and causing a disease or condition. The two main factors that make infection possible are:

The natural ability of the infecting agent to pass through natural barriers and tissues, which is known as virulence.

The lability or efficiency of a person’s general defence system during the various phases of the germ’s attack (susceptibility).

People with permanent immune defects get the same types of infections as normal people, e.g. ear infections, sinusitis or pneumonia, but they occur more frequently. These recurrent infections are often more severe, with a higher risk of complications, as they do not respond as easily to the usual medications. Such cases are called recurrent infections.

Bacterial treatments are indicated to prevent recurrent respiratory and urinary tract infections, as they act as immunomodulators, creating a defensive state against the micro-organisms responsible for the infections.


  • Always administer the dose prescribed by your allergist. Should you have any queries or notice any symptoms, please discuss them with your allergist.
  • Apply under the tongue and hold for 3-4 minutes. Swallow the remaining amount. If you notice any pharyngeal discomfort, we recommend spitting out the dose after this time has passed.
  • Take the vaccine on an empty stomach, first thing in the morning. Do not eat for at least 20-25 minutes afterwards.
  • Always take the vaccine at the same time. We recommend setting an alarm on your mobile or watch to avoid forgetting.
  • Store the vaccine in the fridge at a temperature between 2ºC and 8ºC, never in the freezer. Avoid leaving the vaccine in hot places or in direct sunlight.
  • We do not recommend administering the allergy vaccine on the same day as other types of vaccines. We recommend allowing at least 3 to 4 days between each one.
