Keeping a child’s vaccination record up to date is one of the most effective ways to protect children from serious and potentially life-threatening diseases. In 2026, the Brazilian National Childhood Immunization Schedule was updated, introducing important changes in dose schedules, recommendations, and preventive strategies.
In this article, you will learn what has changed in pediatric vaccines in 2026, which doses require special attention, and how parents and caregivers can stay organized to ensure complete immunization.
What Is the National Childhood Immunization Schedule?
The National Immunization Schedule is defined by the Ministry of Health, through the National Immunization Program. It establishes all vaccines offered free of charge by Brazil’s public health system (SUS), organized according to age groups.
This schedule is regularly updated based on scientific evidence, epidemiological data, and advances in vaccine development.
Main Changes in Pediatric Vaccines for 2026
The 2026 updates focus on expanding child protection and improving adherence to the vaccination schedule. Key changes include:
Adjustments to vaccination schedules
Some vaccines have had dose intervals modified or booster shots repositioned to ensure stronger and longer-lasting immune responses, especially during early childhood.
Stronger focus on respiratory disease prevention
Due to seasonal increases in respiratory infections, vaccines aimed at preventing respiratory diseases received greater emphasis, particularly for infants and young children, helping reduce complications and hospitalizations.
Updates to combination vaccines
Vaccines that protect against multiple diseases were adjusted to simplify the immunization process, reducing the number of injections without compromising effectiveness.
Expanded recommendations for specific groups
Children with chronic conditions, prematurity, or other health risks now have more detailed vaccination guidelines, with schedules adapted based on medical evaluation.
Vaccines That Remain Essential in 2026
Despite updates, several vaccines continue to be fundamental to child health protection:
-
BCG
-
Hepatitis B
-
Pentavalent vaccine
-
Polio
-
Pneumococcal vaccine
-
Rotavirus
-
MMR (measles, mumps, and rubella)
-
Varicella (chickenpox)
Following the recommended schedule for these vaccines is crucial to prevent the re-emergence of diseases that were previously under control.
Why Following the Updated Schedule Matters
Keeping vaccinations up to date ensures:
-
Individual protection for the child
-
Reduced circulation of viruses and bacteria
-
Community protection (herd immunity)
-
Prevention of outbreaks and epidemics
-
Safer school and social environments
Delayed vaccinations may require longer and more complex catch-up schedules.
Where Can Children Be Vaccinated in 2026?
All vaccines included in the national schedule remain available free of charge at public health clinics (UBS) throughout Brazil. Parents should bring the child’s vaccination card and confirm whether any age-specific updates apply.
How Can Parents Stay Organized?
Simple strategies can help families keep vaccinations on track:
-
Set reminders on your phone
-
Review the vaccination card at every pediatric visit
-
Take advantage of national vaccination campaigns
-
Ask questions directly at health clinics or with your child’s pediatrician
