Understanding Influenza and Its Impact

The influenza virus is notorious for its ability to spread quickly, causing widespread illness, hospitalisation, and in severe cases, even death. Every year, the flu makes its rounds across the country, often peaking during the winter months. According to the Australian Department of Health, the flu causes thousands of hospitalisations each year, with those aged over 65, young children, pregnant women, and individuals with underlying health conditions being at higher risk of complications.

What’s more, the flu is not just a mild illness. While many people may experience mild symptoms like fever, sore throat, and muscle aches, others can develop life-threatening complications such as pneumonia, bronchitis, or organ failure. With hospitals often overwhelmed during peak flu season, getting vaccinated is one of the best ways to reduce your chances of catching the virus and, in turn, lessen the burden on healthcare services.

Why Do You Need the Flu Vaccine Every Year?

• Flu Strains Change Each Year

One of the biggest reasons flu vaccinations are needed annually is the virus’s ability to change from year to year. The flu virus mutates frequently, which means new strains emerge regularly. This process, known as antigenic drift, leads to variations in the virus that can evade the immunity built up from the previous year’s vaccination.

Each year, global health organisations such as the World Health Organisation (WHO) and the Australian Influenza Surveillance Committee assess which strains of the flu are most likely to be circulating. Based on this data, they update the vaccine to target the most prevalent strains for that particular flu season. As a result, the vaccine you received last year may not protect you from the new strains that have emerged, making a yearly booster shot necessary for optimal protection.

• Immunity Decreases Over Time

Even though the flu shot helps build immunity, this protection doesn’t last forever. Over time, your body’s immune response to the flu vaccine weakens, and you become more susceptible to infection again. This is why flu shots are recommended every year, to boost your immunity and give you the best chance of avoiding the flu.

This annual revaccination helps maintain high levels of protection in the population, which can prevent widespread outbreaks and help protect those who are particularly vulnerable, such as the elderly, young children, and individuals with weakened immune systems.

• The Severity of the Flu Can Vary

Each year’s flu season can vary in severity. Some seasons may see only a mild flu strain circulating, while others can be more aggressive and lead to higher hospitalisation rates. The flu vaccine is designed to offer protection against the most common and severe strains, so getting vaccinated each year ensures that you are protected, regardless of the severity of the season. Even if you don’t experience severe symptoms, the flu can still cause you to miss work, school, or other important activities.

• Protecting Those Around You

Vaccination isn’t just about protecting yourself; it’s about protecting others, particularly those who are more vulnerable to the flu’s effects. Infants, the elderly, pregnant women, and those with chronic conditions like asthma condition, diabetes, or heart disease are more likely to experience severe flu complications. By getting your flu shot, you help reduce the overall spread of the virus, which can ultimately protect those who may not be able to get vaccinated themselves or may not respond well to the vaccine.

Herd immunity works when a large proportion of the population is vaccinated, making it less likely that the flu virus will spread widely. While some people may be unable to get vaccinated due to medical reasons, the more people who are vaccinated, the less opportunity the virus has to spread within communities.

The Benefits of Flu Vaccination

1. Reduces the Risk of Hospitalisation

Flu vaccinations are particularly important for the elderly and those with pre-existing health conditions. Every year, thousands of Australians are hospitalised due to complications from the flu. These hospitalisations can be avoided by getting vaccinated and reducing the severity of symptoms if someone does contract the virus.

2. Prevents the Spread of the Virus

Even if you’re not personally severely affected by the flu, getting vaccinated helps reduce the overall spread of the virus in the community. This is especially important in areas where large groups of people gather, such as schools, workplaces, and public transport. By lowering the chances of becoming infected, you help keep the virus from spreading to others, particularly those who are more at risk.

3. Helps the Healthcare System

During flu season, the healthcare system often becomes overwhelmed with flu-related cases. This puts immense pressure on hospitals, medical clinics, and healthcare workers, potentially delaying care for other conditions. A widespread vaccination campaign reduces the number of people who get sick and need hospitalisation, allowing the healthcare system to operate more smoothly and efficiently.

4. Protection Against Other Illnesses

While the flu vaccine doesn’t protect against COVID-19 or other respiratory infections, it’s essential to note that flu shots can help lessen the burden of any other illnesses circulating. For example, during flu season, flu and COVID-19 might circulate simultaneously. By getting vaccinated against the flu, you’re also reducing the risk of experiencing “co-infection,” which can worsen outcomes.

Who Should Get the Flu Vaccine?

In Australia, the flu vaccine is recommended for everyone aged six months and over, but it’s particularly important for certain groups of people:

• Pregnant Women: Pregnancy can make women more susceptible to severe complications from the flu. The vaccine is safe and recommended for pregnant women, as it also protects the baby.
• Children Aged 6 Months to 5 Years: Young children are more likely to suffer complications from the flu. Vaccinating children can help reduce the risk of serious illness.
• Older Adults (65+): People over 65 are more likely to experience severe flu complications, including pneumonia, which can lead to hospitalisation or even death.
• People with Chronic Conditions: Those with conditions like asthma, diabetes, or heart disease are at greater risk of developing complications from the flu.
• Healthcare Workers: Health professionals who are regularly exposed to sick individuals should get vaccinated to protect both themselves and their patients.
