The importance of flu vaccinations is to be considered especially for those at risk of severe illness or complications of a flu illness. Flu can lead to complications and hospitalisation. Vaccination is the most effective way to protect against flu.
The flu, or influenza, is a contagious respiratory illness that can cause mild to severe symptoms. While many people recover from the flu without complications, it can be a serious health risk for certain groups of people.
Individuals with underlying health conditions, the flu can escalate quickly. Chronic illnesses such as diabetes, asthma, heart disease, and compromised immune systems increase the likelihood of severe symptoms. The flu vaccine is designed to reduce the severity of the illness. If vaccinated, those at risk significantly lower their chances of complications, such as pneumonia or exacerbation of existing conditions.
Certain individuals are more susceptible to severe flu illness. These groups include older people, young children, pregnant women, as well as those with chronic health conditions and weakened immune systems.
By vaccinating as many of the population, we create a layer of protection for those who are most vulnerable to the flu’s dangers, such as infants under six months who are too young to receive the vaccine themselves but ensuring that caregivers and family members are vaccinated helps to create a protective cocoon around them.
The flu seasons can overwhelm healthcare systems, especially during years with high infection rates. Those at risk of complications are more likely to require hospitalisation, which strains resources and medical staff.
The flu causes fever, chills, and fatigue, it can lead to complications such as bronchitis, sinus infections, ear infections, and worsening of chronic conditions. The flu can trigger severe outcomes like heart attacks or strokes, particularly in older adults.
Flu vaccines have been extensively studied and proven to be safe for many people, including those with pre-existing conditions. Side effects are mild, such as soreness at the injection site or low-grade fever. The benefits of the vaccine far outweigh the risks, especially for those with heightened susceptibility to severe flu symptoms.
Vaccinating helps protect the broader community. When more people are immunised, the flu virus has fewer opportunities to spread, reducing overall transmission rates. This is called herd immunity and is beneficial for protecting those who cannot be vaccinated, such as infants and individuals with severe allergies to vaccine components.
A flu vaccine is the best way to protect yourself and others from the flu. It reduces the risk of illness, if you catch the flu – you will have milder symptoms, and there is protection for others by reducing its spread protecting those who are not able to get vaccinated.
What can you do?
If you are considered old or vulnerable, ask about your flu vaccination.
Get vaccinated early offering protection before the virus is widespread.
Encourage family and friends eligible for vaccination to take up the flu vaccination.
It is a collective responsibility; by protecting yourself, you also safeguard the broader community.
