Keeping vaccination records current is a contribution to community protection
Em Várzea Grande, no coração do Brasil, menos de três em cada dez pessoas pertencentes aos grupos prioritários buscaram a vacina contra a gripe, mesmo enquanto doenças respiratórias avançam entre crianças, idosos e portadores de doenças crônicas. A campanha de vacinação, iniciada ainda em março, encontra resistência silenciosa — não de hostilidade declarada, mas da inércia humana diante de riscos invisíveis. É uma tensão antiga na saúde pública: a distância entre o que se oferece e o que se aceita, entre a proteção disponível e a vulnerabilidade que persiste.
- Com apenas 28,69% dos grupos prioritários vacinados, Várzea Grande enfrenta uma corrida contra o tempo enquanto casos de síndrome respiratória aguda grave lotam prontos-socorros e UPAs.
- Crianças e idosos são os mais afetados pela circulação antecipada do vírus influenza, que chegou antes do esperado e pegou a população despreparada.
- A secretária municipal de saúde e enfermeiras de vigilância epidemiológica intensificam campanhas, unidades móveis e busca ativa — mas o fosso entre esforço e adesão permanece alarmante.
- Vacinas disponíveis gratuitamente nas 25 unidades de saúde do município podem reduzir hospitalizações em até 75% em crianças, segundo a OPAS, mas a maioria dos elegíveis ainda não compareceu.
- A expansão da campanha para a população geral depende de autorização do Ministério da Saúde em Brasília, deixando a cidade presa nos limites do que já foi permitido enquanto os casos sobem.
No início de junho, Várzea Grande registrava um número que preocupava as autoridades de saúde: apenas 19.560 pessoas — menos de 29% dos 68.180 integrantes dos grupos prioritários — haviam se vacinado contra a gripe. A campanha corria desde março, mas a adesão permanecia baixa enquanto as doenças respiratórias avançavam pela cidade.
Os grupos prioritários abrangiam uma fatia ampla e vulnerável da população: crianças de seis meses a seis anos, pessoas acima de sessenta anos, gestantes, puérperas, trabalhadores da saúde e da educação, povos indígenas, quilombolas, pessoas com doenças crônicas ou deficiências permanentes, além de motoristas, trabalhadores portuários e pessoas em situação de rua. Apesar da abrangência, a maioria ainda não havia buscado proteção.
A secretária municipal de saúde, Valéria Nogueira, reconheceu a gravidade da situação. Prontos-socorros e UPAs estavam sobrecarregados, especialmente com crianças e idosos com dificuldades respiratórias. A enfermeira de vigilância epidemiológica Maria José Neves reforçou os dados: vacinas disponíveis podem reduzir hospitalizações entre 30% e 75%, dependendo da faixa etária, e a meta federal de cobertura total entre crianças e idosos — necessária para atingir a imunidade coletiva — estava longe de ser alcançada.
As 25 unidades básicas de saúde do município continuavam oferecendo doses gratuitamente, mas apenas para os grupos autorizados. A expansão da campanha para a população geral dependia de uma decisão ainda pendente do Ministério da Saúde. Enquanto Brasília não se pronunciava, a cidade seguia trabalhando com o que tinha — e o relógio não parava.
By the second week of June, fewer than three in ten people who should have gotten a flu shot in Várzea Grande had actually done so. The numbers were stark: 19,560 people vaccinated out of 68,180 who belonged to priority groups—a coverage rate of just under 29 percent. The city's health department had been running the campaign since late March, but uptake remained stubbornly low even as respiratory illnesses spread through the community.
The priority groups were broad and specific: children between six months and six years old, anyone over sixty, pregnant women and new mothers, healthcare and education workers, indigenous peoples, quilombo residents, people with chronic conditions or permanent disabilities, police and rescue personnel, truck drivers, public transit workers, port workers, and people experiencing homelessness. Together they represented the population most vulnerable to severe flu complications. Yet most of them had not sought out a vaccine.
Valéria Nogueira, the municipal health secretary, acknowledged the situation was troubling. Respiratory illness cases had climbed noticeably, especially among children, the elderly, and those already managing chronic diseases. The city had been pushing awareness campaigns, conducting active outreach, and running mobile vaccination units to try to reach more people. But the gap between effort and result remained wide. Nogueira framed vaccination as essential—a tool to prevent serious complications and reduce cases of severe acute respiratory syndrome. The message was clear: this was not optional.
The campaign itself had started early, in late March, because the influenza virus had begun circulating ahead of schedule. The initial phase had ended in May, but the federal Health Ministry had not yet authorized expanding vaccination beyond the priority groups. So the twenty-five health clinics across the municipality continued to offer doses only to those designated populations, waiting for word from Brasília to open it up to everyone else.
Maria José Neves, an epidemiological surveillance nurse, explained what she was seeing on the ground. Emergency rooms and urgent care clinics were packed with people struggling to breathe. Children and elderly patients made up a large share of those seeking help. The virus was circulating, and it was hitting hard. She pointed to data from the Pan-American Health Organization showing that current flu vaccines could cut hospitalizations by 30 to 40 percent in adults and reach effectiveness rates as high as 75 percent in children. The federal government had set a target of 100 percent coverage among children and the elderly to achieve what epidemiologists call herd immunity—the point at which enough people are protected that the virus struggles to spread.
Nogueira returned to a simple message: vaccination remained the strongest defense against outbreaks, severe illness, and hospital admissions. The vaccines were safe, effective, and free at every basic health clinic. Keeping vaccination records current was not just an individual choice—it was a contribution to community protection. But that framing, however sound, had not yet moved nearly 71 percent of the priority population to seek a dose.
The next step depended on federal action. The Health Ministry would decide when, or if, to expand the campaign beyond priority groups. Until that authorization came, the city could only work with the population it had been given permission to vaccinate. The clock was running, respiratory cases were climbing, and the gap between who needed protection and who had received it remained stubbornly wide.

La Conversación del Hearth Otra perspectiva de la historia
Why do you think so few people in the priority groups actually came in for the shot?
That's the question everyone's asking. The vaccine is free, it's available at twenty-five clinics, and the health department has been pushing hard. But people don't always act on what they're told, even when it's in their interest.
Is it distrust of the vaccine itself, or just inertia?
Probably both. Some people are skeptical about vaccines generally. Others just haven't gotten around to it—they're busy, they don't think they're at risk, they forget. When you're managing a chronic illness or raising young children, a flu shot might not feel urgent until you're already sick.
But the health secretary said respiratory cases are surging. Shouldn't that be urgent?
You'd think so. But the surge is happening in hospitals and clinics, not necessarily in people's homes yet. If you haven't had a sick child or elderly relative in the ICU, the threat feels abstract.
What happens if coverage stays this low?
The virus keeps spreading. More people get seriously ill. More hospitalizations. The whole point of vaccinating priority groups is to protect the most vulnerable and reduce the overall burden on the system. At 29 percent coverage, you're not getting that protection.
Can the city do anything else to move the needle?
They're already doing mobile clinics and active outreach. What might help is making it even easier—maybe vaccination at schools, at senior centers, at workplaces. But ultimately, the federal government has to decide whether to open it up to the general population. Right now they're holding the line at priority groups only.
