Every patient hospitalized with influenza in Passo Fundo arrived unvaccinated.
No norte do Rio Grande do Sul, a influenza cobra um preço que poderia ter sido evitado. Oito vidas foram perdidas e mais de cem pessoas foram hospitalizadas nos primeiros meses de 2026 — todas elas, segundo as autoridades de saúde, sem vacinação. Em uma região onde apenas 42% dos grupos prioritários receberam a vacina, bem abaixo da meta nacional de 90%, a crise revela não apenas uma falha logística, mas uma ruptura no pacto coletivo de proteção que a saúde pública exige.
- Oito mortes e 109 hospitalizações por influenza na macrorregião Norte do RS em 2026 — incluindo uma criança, um adolescente e uma idosa, todos não vacinados — apontam para uma emergência silenciosa em curso.
- A cobertura vacinal despencou: apenas 42,55% dos grupos prioritários foram imunizados na região, contra uma meta de 90%, e em Passo Fundo apenas 16% das crianças de seis meses a cinco anos receberam a vacina.
- Passo Fundo concentra três das oito mortes e registra taxa de mortalidade hospitalar de 12,5% — acima da média estadual —, com um em cada três pacientes hospitalizados precisando de UTI.
- As autoridades municipais intensificaram a campanha de vacinação, distribuindo mais de 46 mil doses desde março, com novo lote de 5 mil doses chegando recentemente para reforçar os esforços até 31 de maio.
- O estado inteiro soma 743 hospitalizações e 53 mortes em 2026, com quase 28% dos internados necessitando de cuidados intensivos — números que as autoridades vinculam diretamente às lacunas na imunização.
O norte do Rio Grande do Sul enfrenta uma onda de influenza que, nos primeiros cinco meses de 2026, já ceifou oito vidas e enviou mais de cem pessoas aos hospitais. A Macrorregião Norte, formada por 147 municípios e tendo Passo Fundo como polo central, tornou-se o epicentro de uma crise que as autoridades de saúde atribuem diretamente ao colapso nas taxas de vacinação entre os grupos mais vulneráveis.
A cobertura vacinal entre idosos, gestantes e crianças de seis meses a cinco anos chegou a apenas 42,55% na região — uma queda acentuada em relação aos 56% alcançados em 2025. No estado como um todo, o índice é de 41,61%, muito aquém da meta de 90% estabelecida pelo Ministério da Saúde. Em Passo Fundo, o cenário é ainda mais preocupante: apenas 16% das crianças pequenas foram imunizadas, e todas as pessoas hospitalizadas pela doença na cidade chegaram sem vacinação.
As três mortes registradas em Passo Fundo ilustram a dimensão humana da crise: uma criança entre um e quatro anos, um adolescente e uma idosa acima de oitenta anos — nenhum deles vacinado. A taxa de mortalidade hospitalar na cidade é de 12,5%, superior à média estadual de 7,13%, e um em cada três pacientes internados precisou de UTI.
Em resposta, a prefeitura de Passo Fundo intensificou sua campanha, administrando mais de 29 mil doses desde março e recebendo recentemente um novo lote para reforçar os esforços até o fim de maio. As autoridades são diretas: as mortes e internações têm rosto e têm causa — e essa causa é a ausência da vacina.
The northern region of Rio Grande do Sul is confronting a surge in influenza that has claimed eight lives and sent more than a hundred people to hospitals in the first five months of 2026. The Macrorregião Norte, a sprawling area of 147 municipalities anchored by the city of Passo Fundo, has become the focal point of a public health crisis that officials trace directly to a collapse in vaccination rates among the groups most vulnerable to severe illness.
The numbers tell a stark story. In the six health districts that make up the northern macroregion, vaccination coverage among priority groups—elderly people, pregnant women, and children between six months and five years old—has reached only 42.55 percent. That represents a sharp drop from 2025, when the same region achieved 56 percent coverage after administering nearly 260,000 doses. This year, through May, the region has delivered just under 130,000 doses. Across the entire state, the picture is similarly grim: coverage sits at 41.61 percent, nowhere near the 90 percent target set by Brazil's Ministry of Health.
Passo Fundo, the region's largest city and its economic and medical hub, has recorded three of the eight deaths. The first victim was a child between one and four years old, who died unvaccinated. The second was an adolescent between twelve and nineteen. The third was an elderly woman over eighty. None of them had received the influenza vaccine. In Passo Fundo alone, twenty-four people have been hospitalized with influenza this year, and one in three of those patients required intensive care. The city's hospital death rate from the disease stands at 12.5 percent, above the state average of 7.13 percent.
The vulnerability is most acute among the youngest children. In Passo Fundo, only 16.03 percent of children aged six months to five years have been vaccinated—a figure that haunts health officials given that six hospitalizations in the city have occurred in that age group. Among pregnant women, coverage reaches just 31.82 percent. Even among people over sixty, where vaccination rates are highest, only 39.86 percent have received the shot. Every patient hospitalized with influenza in Passo Fundo so far this year arrived unvaccinated.
The state of Rio Grande do Sul as a whole has recorded 743 hospitalizations and 53 deaths from influenza in 2026. The incidence rate stands at 8.28 cases per 100,000 residents. Nearly 28 percent of hospitalized patients have required ICU beds. These are not abstract numbers—they represent people whose illness became severe enough to require hospital admission, many of them in their most vulnerable moments.
In response to the surge, Passo Fundo's municipal government has intensified its vaccination campaign. Since launching the push on March 30, the city has received more than 46,000 doses and has administered just over 29,000 of them. A fresh shipment of more than 5,000 doses arrived recently to bolster efforts. The campaign continues through May 31, though vaccination remains restricted to priority groups per federal guidance. Health authorities have been explicit about the connection between the deaths and hospitalizations and the vaccination gap, particularly among children, elderly people, and those with chronic illnesses. The message is clear: the people dying are the people who did not get vaccinated.

The Hearth Conversation Another angle on the story
Why has vaccination coverage dropped so sharply from last year? In Passo Fundo, the region went from 56 percent to 42 percent in a single year.
The source doesn't explain the cause directly, but the numbers suggest either reduced access, reduced demand, or some combination. The fact that they've had to intensify the campaign since late March implies awareness that uptake was lagging.
The most striking detail is that every single hospitalized patient in Passo Fundo was unvaccinated. Does that suggest the vaccine is working, or that people simply aren't getting it?
Both, really. It suggests the vaccine is effective—the vaccinated aren't ending up in hospitals. But it also means the unvaccinated population is bearing the full weight of the illness. That's not a failure of the vaccine; it's a failure of the campaign to reach people.
A child between one and four years old died. That's the age group with the lowest vaccination rate in the city—16 percent. Is there a pattern there?
Yes. The youngest children are the least protected, and they're also showing up in hospitalizations at higher rates. Six of the twenty-four hospitalizations in Passo Fundo were in that age group. When you have that little coverage in a vulnerable population, you get severe outcomes.
What does it mean that the campaign is restricted to priority groups? Why not vaccinate everyone?
The Ministry of Health is directing resources to the groups at highest risk of severe illness—elderly, pregnant women, young children, people with chronic conditions. It's a triage approach. But it only works if those groups actually get vaccinated, and right now they're not.
The state has applied 155,000 doses this year versus over 212,000 last year. That's a 27 percent drop. Is the vaccine supply the problem?
The source doesn't say supply is constrained. Passo Fundo received over 46,000 doses and has only used about 29,000. It looks more like a demand problem—people aren't coming forward to get vaccinated.
