Chile Braces for Respiratory Virus Season: Experts Urge Early Vaccination
Chile’s Ministry of Health has initiated its 2026 Vaccination and Immunization Campaign on March 1st, a proactive move to shield the population against the anticipated surge in respiratory viruses. Experts from the University of Chile emphasize that timely vaccination against influenza and COVID-19 is crucial for preventing severe illness, hospitalizations, and fatalities.
The Importance of Proactive Immunization
The decision to advance the campaign is rooted in the understanding that vaccine-induced protection isn’t immediate. Dr. Vivian Luchsinger, an immunologist at the University of Chile’s Faculty of Medicine, explains that the immune response takes approximately one to two weeks – or even longer – to reach peak effectiveness. Vaccination before the peak of viral circulation is key.
This strategy aims to ensure that vulnerable populations are adequately protected before the winter months, when respiratory viruses typically spread more rapidly. Dr. Jeannette Dabanch, an infectologist, notes that Chile’s temperate climate allows for predictable timing of influenza increases, usually beginning in late April or early May. Starting the campaign in March allows for progress towards the health authority’s target coverage of 85%.
Beyond Individual Protection: A Community Health Approach
Vaccination isn’t solely about individual well-being; it has broader implications for public health. Dr. Luchsinger highlights that reducing the number of severe cases alleviates strain on healthcare resources, including consultations, emergency rooms, hospital beds, and intensive care units. Early vaccination plays a vital role in mitigating pressure on the healthcare system during peak seasons.
Combining Vaccination with Everyday Precautions
Even as vaccination is paramount, experts stress the continued relevance of preventative measures. Dr. Luchsinger emphasizes that the same strategies used during the COVID-19 pandemic remain effective against other respiratory viruses, including wearing masks when experiencing respiratory symptoms, frequent handwashing, using hand sanitizer, covering coughs and sneezes, and avoiding crowded indoor spaces.
Dr. Dabanch adds that these precautions are particularly important as vaccines aren’t available for all respiratory viruses. Maintaining good hygiene and responsible behavior remains fundamental during periods of increased viral activity.
Addressing Declining Risk Perception
A potential challenge is the decreased sense of risk following the most acute phases of the pandemic. Dr. Luchsinger cautions that SARS-CoV-2 and influenza continue to circulate, causing hospitalizations and deaths, particularly among older adults, pregnant individuals, those with compromised immune systems, and people with chronic illnesses.
Dr. Dabanch concludes, “Vaccines were the primary tool that enabled a return to everyday life after the pandemic, and both influenza and COVID-19 immunizations have proven safe and effective in preventing severe illness and reducing mortality.”
Who Should Prioritize Vaccination?
- Individuals aged 60 and older (influenza) and 65 and older (COVID-19 and pneumococcal vaccine).
- Healthcare personnel in public and private facilities.
- Individuals with chronic conditions aged 11 to 59 with risk factors.
- Pregnant individuals at any stage of pregnancy.
- Infants and schoolchildren from 6 months to 5th grade.
- Preschool and school staff up to 8th grade.
- Newborns and infants born after October 1, 2025 (RSV immunization).
Frequently Asked Questions
Q: How long does it take for the vaccine to provide protection?
A: The immune response takes around one to two weeks, or even longer, to reach its peak.
Q: What if I’ve already had COVID-19? Do I still need to get vaccinated?
A: Yes. Vaccination provides additional protection, even if you’ve previously been infected.
Q: Are there any side effects from the vaccines?
A: Common side effects are usually mild, such as pain at the injection site, fatigue, or mild fever.
Q: Where can I get vaccinated?
A: Contact your local healthcare provider or check the Ministry of Health website for vaccination locations.
Did you know? The Ministry of Health has expanded the vaccination campaign to include immunization against Respiratory Syncytial Virus (RSV) for newborns and infants born after October 1, 2025.
