The Flu Comes Back: Understanding Seasonal Influenza and Vaccination
The flu comes back, like every year,” begins Aurore Girard, general practitioner and vice-president of the Scientific Society of General Medicine. The eternal return, therefore. But not in the same way, since the influenza virus, responsible for the flu, is classified into several strains, themselves subdivided into subtypes. Experts use the circulation of the flu virus in the southern hemisphere (which begins winter before us) to predict the strains expected in Europe.
Understanding Influenza Strains and Vaccination
Every year, the influenza virus undergoes changes leading to new strains of the virus. The two strains that circulated in Australia belong to subtype A and are covered by the vaccine,” emphasizes Dr. Girard. Vulnerable people are encouraged to get vaccinated from mid-October to avoid serious illness, hospitalizations, and the risk of death. It is noteworthy that more than 90% of flu-related deaths concern people over 65. Additionally, individuals living with underlying chronic pathologies, such as:
- Cardiac issues
- Renal problems
- Pulmonary complications
- Endocrine disorders (e.g., diabetes)
are also at heightened risk of complications from the flu.
The Flu Season in Belgium (2023-2024)
In 2023, the flu season in Belgium lasted eleven weeks, with hospitalizations peaking at the end of January 2024. Around 550,000 Belgians, or 5% of the population, contracted the flu, and among them, 1 in 1,000 people developed serious complications requiring hospitalization.
The Importance of Vaccination Rates
Authorizing pharmacists to administer the vaccine has boosted the vaccination rate. Last year, 20% of vaccines were administered in pharmacies. However, despite these efforts, the overall vaccination rate among people at risk remains well below the World Health Organization (WHO) recommendations. Key statistics reveal:
| Group | Vaccination Rate (%) | WHO Recommendation (%) |
|---|---|---|
| Seniors (65+) | 50.7 | 75 |
| Chronically Ill | 43.4 | 75 |
With barely half of the vulnerable population vaccinated in Belgium, it becomes imperative to increase awareness and accessibility of the influenza vaccine to reduce hospitalizations and mortality rates.
Benefits of Getting Vaccinated Against the Flu
Vaccination against the flu comes with numerous benefits, particularly for vulnerable groups. Here are some key advantages:
- Reduces Severity: The flu vaccine decreases the severity of illness in those who do contract the virus.
- Protects Vulnerable People: By getting vaccinated, you help to protect those around you who may not be able to be vaccinated, including young children or people with specific health conditions.
- Prevents Hospitalizations: Getting the flu vaccine significantly reduces the risk of hospitalization due to flu-related complications.
- Community Health: Higher vaccination rates contribute to herd immunity, protecting the entire community from outbreaks.
Practical Tips for Flu Season
As flu season approaches, it’s essential to adopt proactive measures to protect yourself and others. Here are some practical tips:
- Get Vaccinated: Make sure to receive your flu shot from a healthcare provider or nearby pharmacy by mid-October.
- Practice Good Hygiene: Regular handwashing, using hand sanitizers, and avoiding close contact with sick individuals can help reduce flu transmission.
- Maintain a Healthy Lifestyle: Eating a balanced diet, exercising regularly, and getting adequate sleep can bolster your immune system.
Case Studies: Impact of Vaccination on Seasonal Flu
Understanding the impact of vaccination can be further illustrated through case studies. For instance:
- Case Study 1: A senior center in Belgium offered flu vaccinations to its residents, resulting in a dramatic decline in flu cases from previous years.
- Case Study 2: A community health initiative focused on raising awareness about flu vaccinations improved the vaccination rate among local seniors by 30%.
First-Hand Experience: The Importance of Vaccination
A local nurse, Marie Dupont, shares her first-hand experience regarding the importance of flu vaccinations:
“In my years of working in healthcare, I’ve seen how devastating the flu can be for our elderly population. Vaccination not only protects them but also brings peace of mind to families. I always encourage everyone, especially those at higher risk, to get their flu shot each year.”
Conclusion
Every year, influenza poses significant health risks, especially for vulnerable populations. Understanding the strains and the importance of vaccination can help mitigate these risks. Awareness campaigns and increased accessibility are vital in improving vaccination rates and protecting community health during flu season.
