Contraindications of Vaccines

Contraindications of vaccines only apply to attenuated bacteria or virus vaccines, ie vaccines that are made from live bacteria or viruses, such as the BCG vaccine, chickenpox, chicken pox, polio and yellow fever .

Thus, these vaccines are contraindicated to:

• Immunosuppressed individuals, such as patients with AIDS, on chemotherapy or transplanted, for example;
• Individuals with cancer;
• Individuals receiving high-dose corticosteroids;
• Pregnant.

All other vaccines that do not contain attenuated bacteria or virus can be administered.

In case the individual is allergic to any component of the vaccine, he should consult an allergist to decide whether or not the vaccine should be administered, such as:

• Allergy to the egg : influenza vaccine, triple viral and yellow fever;
• Allergy to gelatin: influenza vaccine, triple viral, yellow fever, rabies, chickenpox, triple bacterial: diphtheria, tetanus and whooping cough.

In this case, the allergist should assess the risk / benefit of the vaccine and thus authorize its administration.
