Only six students carried proof of the second dose
En una escuela del distrito de Viñani, en Tacna, la confirmación de un segundo caso de sarampión expuso una brecha silenciosa: la mayoría de los niños en el aula afectada carecía de la vacuna que podría haberlos protegido. Las autoridades de salud y educación respondieron con rapidez, eligiendo la precisión quirúrgica sobre el cierre masivo, conscientes de que detrás de cada niño sin vacunar había una familia con sus propias dudas, creencias o miedos. La escena refleja una tensión que trasciende las fronteras de Tacna: la fragilidad de la confianza colectiva en tiempos en que las enfermedades prevenibles encuentran los huecos que deja la hesitación.
- Solo seis de aproximadamente treinta estudiantes en el aula afectada contaban con la segunda dosis de la vacuna contra el sarampión, una cifra que alarmó a las autoridades desde el primer momento.
- La negativa de muchos padres a vacunar a sus hijos —motivada por creencias personales, convicciones religiosas o desconfianza hacia las vacunas— dejó a una gran parte del alumnado expuesta a una enfermedad altamente contagiosa.
- Para evitar el cierre total del colegio, las brigadas médicas adoptaron una estrategia aula por aula, aplicando cierres preventivos de una semana únicamente donde se detectaran estudiantes sin vacunar.
- La llegada del invierno intensifica la urgencia: la temporada de enfermedades respiratorias amplifica el riesgo de transmisión del sarampión entre niños no protegidos.
- Las autoridades anunciaron la expansión de las campañas de vacunación a otros colegios de alta matrícula en la región, apostando por la prevención antes de que surjan nuevos casos.
Cuando las autoridades de salud y educación llegaron al colegio Prócer Manuel Calderón de la Barca, en el barrio Viñani de Tacna, los registros de vacunación revelaron algo inquietante: en el aula donde se había confirmado el segundo caso de sarampión de la región, apenas seis de unos treinta estudiantes contaban con la segunda dosis de la vacuna.
La respuesta fue inmediata. El director de la UGEL local, Julio Tapia Calizaya, llegó junto al director regional de educación y al director regional de salud. Las brigadas médicas del centro de salud de Viñani recorrieron el colegio para evaluar el estado de vacunación de cada alumno y administrar dosis donde fuera necesario. La semana anterior, el primer caso de sarampión había obligado al cierre temporal del colegio Santísima Niña María —que contaba con cerca del ochenta por ciento de cobertura vacunal—. Esta vez, las autoridades querían actuar con mayor precisión.
En lugar de cerrar toda la institución, decidieron intervenir salón por salón, de primero a sexto grado. El cierre preventivo de una semana se aplicaría únicamente a las aulas donde se identificaran estudiantes sin vacunar. Tapia Calizaya explicó que la baja cobertura obedecía a rechazos parentales por creencias personales, convicciones religiosas o lo que describió como una alarma injustificada frente a las vacunas. Hizo un llamado directo a los padres para que firmaran los consentimientos informados sin demora.
El contexto agravaba la urgencia: el invierno se acercaba a Tacna, y con él el aumento estacional de enfermedades respiratorias. Las brigadas médicas anunciaron que extenderían las campañas de vacunación a otros colegios con alta matrícula, reforzando también medidas básicas como el uso de mascarillas y el lavado frecuente de manos.
Más allá del operativo sanitario, la intervención dejó al descubierto una fractura en la confianza comunitaria. Las autoridades evitaron señalar directamente a los padres, pero su mensaje fue claro: la hesitación tiene un costo concreto, medido en semanas de clases perdidas y en el riesgo de que el segundo caso no sea el último.
When health and education officials arrived at Prócer Manuel Calderón de la Barca school in Tacna's Viñani neighborhood on a routine Tuesday, they were not prepared for what the vaccination records would reveal. A second measles case had been confirmed in the region, and the discovery sent a chill through the classroom where it occurred: only six students—out of roughly thirty—carried proof of the second dose of measles vaccine.
The intervention was swift and coordinated. Julio Tapia Calizaya, director of the local education authority, arrived alongside Yuri Mejía Tang, the regional education director, and Julio Aguilar Vilca, the regional health director. Medical brigades from the Viñani health center fanned out through the school to assess vaccination status and administer doses where needed. The officials had been preparing for this moment since the previous week, when the first measles case had forced a different school—Santísima Niña María—to close temporarily. This time, they were determined to act faster and smarter.
The gap in vaccination coverage was staggering. Tapia Calizaya explained that the low numbers stemmed from parental refusal rooted in personal beliefs, religious conviction, or what he called "unjustified alarm" about vaccines. The contrast with the other affected school was stark: Santísima Niña María had achieved roughly eighty percent vaccination coverage among its students, a rate that had allowed authorities to limit the preventive closure to a single week. Here, at Prócer Manuel Calderón de la Barca, the situation demanded a different approach.
Rather than shut down the entire school, officials decided to target their response by classroom. Health personnel moved through each section from first to sixth grade, documenting who was protected and who was not. If an unvaccinated student was identified, the closure would apply only to that specific classroom and only for one week—a surgical intervention rather than a blunt one. The priority, Tapia Calizaya stressed, was to protect the academic year while protecting the children. He appealed directly to parents to sign informed consent forms immediately, allowing health workers to vaccinate their children without further delay.
The timing mattered. Winter was arriving in Tacna, bringing with it the seasonal surge in respiratory illnesses. Measles, highly contagious and preventable only through vaccination, posed a particular threat to any gathering of unprotected children. The officials were racing against both the calendar and the clock of disease transmission. Medical brigades announced plans to expand beyond this single school, moving into other high-enrollment institutions across the region to strengthen vaccination campaigns and reinforce basic preventive measures: masks worn consistently, hands washed frequently, children dressed warmly against the cold.
What emerged from the intervention was a portrait of a public health system trying to manage not just disease, but the fracture in community trust that had left so many children unprotected. The officials did not blame parents outright, but their language was clear: collaboration was essential, and the cost of hesitation was measured in weeks of lost schooling and the risk of further spread. As the vaccination teams continued their work, the question hanging over Tacna was whether the appeal would reach enough families in time, or whether the second case would become the first of many.

We've asked Health to evaluate and verify the vaccination status of the children. We're reviewing all sections from first to sixth grade, and if we find unvaccinated cases, suspension would only affect that specific section and only for one week.— Julio Tapia Calizaya, director of the local education authority
We urge parents to sign informed consent forms immediately so health personnel can vaccinate their children and avoid delays or class suspensions.— Julio Tapia Calizaya
The Hearth Conversation Another angle on the story
Why did only six students have the second dose in a classroom of thirty? That's an unusually low number.
It comes down to vaccine hesitancy rooted in personal beliefs and religious objections. Parents refused consent, so the children never received the shot. It's not a knowledge gap—it's a trust gap.
But the other school, Santísima Niña María, had eighty percent coverage. What was different there?
That's the puzzle. Both schools are in the same region, same health system, same messaging. The difference might be in how individual communities received the information, or which voices they trusted. We don't know yet.
So the officials decided not to close the whole school. Why take that risk?
Because closing schools has its own cost—lost instruction, disrupted families, economic impact. They chose precision: isolate the unvaccinated classroom, vaccinate quickly, limit the closure to one week. It's a gamble that speed and targeted action can contain the spread.
And if it doesn't work? If measles spreads beyond that classroom?
Then they'll have to close more broadly. But winter is coming, respiratory illnesses are rising, and they're already planning to expand vaccination campaigns to other schools. They're trying to get ahead of it.
What do the parents who refused vaccination say now?
The officials didn't report their response. They just appealed for immediate consent forms. Whether that appeal lands depends on whether parents believe the risk of measles is greater than their fear of the vaccine.
