Alarming Drop in Childhood Vaccination Rates Sparks Health Concerns in Argentina
Table of Contents
Immunization coverage for key childhood vaccines in Argentina has plummeted to record lows in 2024, raising serious concerns among health officials and experts about the potential resurgence of preventable diseases. Official data reveals that less than half of children received crucial vaccinations upon entering primary school, with coverage rates for several doses falling between 6 and 12 percentage points compared to the previous year.
A Record Collapse in Immunization
The figures are stark. According to the Ministry of health, this represents the most important decline in vaccination rates in the last 15 years. Beyond the “vaccines of 5 and 6” – those administered between the 5th and 1st grade – a 10 percentage point drop was recorded across all vaccines recommended for 11-year-olds.
Of particular concern is the low uptake of the human papillomavirus (HPV) vaccine, with barely half of pre-adolescent girls and boys receiving the single dose recommended to protect against future infections that can lead to cancer. These findings stand in contrast to recent optimistic reports from the Ministry of Health highlighting improvements in immunization coverage for infants during their “first thousand days” of life.
reinforcements at Risk: polio and Beyond
The polio vaccine, though considered eradicated in the country, remains a critical concern. “Polio has been eradicated in the country, but if the schemes are not followed, thay will inevitably re-enter because they are not diseases eradicated from the world,” explained Dr.Rüttimann.
Rüttimann illustrated the risk with a timely example: “Now, such as, the National Team is going to Angola. It is a country in which there are poliomyelitis.If a player does not have the reinforcements applied, they run the risk of becoming infected. This is a reality.”
Measles, HPV, and Meningococcus: A Multifaceted Crisis
Coverage rates for the triple viral vaccine, protecting against mumps, rubella, and measles, have also dropped considerably, reaching 46.7% in 2024, down from nearly 90% since 2009.This is particularly concerning given recent measles outbreaks and heightened vigilance from PAHO.
The chickenpox vaccine, aimed at creating a “collective barrier” to protect vulnerable populations like older adults and pregnant women, was administered to only 45.8% of boys in 2024, a decrease from 52.33% the previous year.
Moreover, the triple bacterial vaccine, protecting against whooping cough, diphtheria, and tetanus, has seen a dramatic decline, falling from coverage rates near 90% in the decade 2009-2019 to just 46.4% in 2024. The vaccine protecting against meningococcus, crucial for protecting younger children, was administered to only 51.9% of the target population last year.
Concerns Extend to pediatrician Confidence
Rüttimann highlighted a worrying trend: a growing lack of confidence among pediatricians regarding the importance of vaccines. “The medical community is having doubts and that makes the problem proliferate, if the mother asks and the pediatrician doubts,” he explained. However, he stressed that “from the point of view of public health, there are aspects in which there can be no doubt.” He affirmed that “vaccines are hypersecure and effective and that many of those that never caused any problems are now being questioned, even though they have eradicated terrible diseases.”
Data Discrepancies and Methodological Shifts
The reported decline appears to contradict earlier statements from the ministry of Health, which claimed “improvements of up to 15 points in 2024.” This discrepancy stems from a change in methodology. The Ministry now incorporates an “expanded coverage by cohort” indicator, which extends the data collection period beyond the calendar year. Specifically, the counting of doses applied included various periods. The Ministry clarified that this new approach aims to provide a more accurate measure of vaccination rates by analyzing cohorts of children over a longer timeframe.
Despite the methodological adjustments, the underlying trend remains clear: vaccination rates in Argentina are declining, leaving the country vulnerable to the resurgence of preventable diseases and underscoring the urgent need for renewed efforts to promote immunization.
