The measles vaccine is available in two versions, the triple-virus vaccine, which protects against 3 diseases caused by viruses: measles, mumps and rubella, or Viral Tetra, which still protects against chicken pox. It is part of the basic immunization schedule of the child and is administered as an injection of attenuated virus against measles.
This vaccine stimulates the individual's immune system, inducing the formation of antibodies against the measles virus. Thus, if the person is exposed to the virus, they already have the antibodies that will prevent the proliferation of the virus, leaving it totally protected. Learn how the immune system works.
What is it for
The measles vaccine is for all people as a form of prevention of the disease and not as a treatment. In addition, it also prevents diseases such as mumps and rubella, and in the case of Tetra Viral also protects from chicken pox.
Usually the first dose of the vaccine is given at 12 months and the second dose is between 15 and 24 months. However, all adolescents and adults who have not been vaccinated can take 1 dose of this vaccine at any stage of life without the need for booster.
