Some additional care needs to be considered in childhood before opting for vaccination against this disease
The yellow fever may threaten especially children, who are the immune system is still immature. However, the vaccine in this age group involves some measures and restrictions – which were discussed in detail in a new document of the Brazilian Society of Pediatrics (SBP) .
To begin with, the text reinforces a crucial point: before 6 months of age, no baby should be immunized against yellow fever . Between 6 and 9 months, the injection is only allowed with the consent of a physician and if there is a need (if the child, for example, lives in a high-risk area of infection transmission).
In addition, experts from the SBP ask for attention with the possible interaction between the vaccine against this disease and others that are typically administered in childhood. More specifically, the ideal is not to offer the yellow fever immunizer simultaneously with the triple viral (measles, rubella and mumps) or the viral tetra (measles, rubella, mumps and varicella) in children under 2 years.
“For children who have not received any of these vaccines, they are advised to take the dose of yellow fever and schedule the triple viral or tetra-viral for at least 30 days thereafter,” explains Dr. Renato Kfouri, president of the Scientific Department of Immunizations SBP , in a press release. “The other vaccines of the calendar can be administered on the same day as the yellow fever,” reassures.
Another thing: as in adults, children and adolescents with strong egg allergy can only receive the injection after careful medical evaluation and within an environment with emergency care conditions. These are peculiarities that, in the end, require a conversation with the pediatrician.
In general, the vaccine is well tolerated. Fever, headache or muscle pain, among other symptoms, affect 2 to 5% of those who take it. Those serious adverse reactions only happen, according to the SBP, in one every 250 thousand doses applied.
