Flu Vaccinations in Hout Bay: Why an Annual Flu Injection Matters

Influenza is more than an unpleasant winter cold. It is a contagious respiratory illness that can cause fever, coughing, body aches, headaches, fatigue and, in some patients, serious complications such as pneumonia or hospitalisation.

South Africa’s 2026 influenza season started unusually early, during the week beginning 9 March. The NICD has advised that seasonal influenza vaccination remains the most effective available protection against flu and severe influenza-related illness.

Hout Bay Family Medical Clinic encourages local residents to consider an annual flu vaccination, particularly before or during the Cape winter months.

What Is the Flu Injection?

The flu injection is an annual vaccine designed to protect against the influenza virus strains expected to circulate during the coming season.

Influenza viruses change over time, which is why the vaccine is updated and administered each year. Protection from previous vaccination also gradually decreases, making annual vaccination important.

The injected influenza vaccine contains inactivated virus and cannot cause influenza. Some people may experience mild, temporary effects such as tenderness at the injection site, tiredness or a slight fever as the immune system responds.

When Should You Get the Flu Vaccine?

In South Africa, the ideal time to receive the flu vaccination is usually during March or April, before influenza becomes widespread during winter.

It takes approximately two weeks after vaccination for the body to develop an adequate immune response. However, the NICD emphasises that it is not necessarily too late to vaccinate after the flu season has started, as vaccination may still provide protection during the remainder of the season.

Residents who have not yet received their 2026 flu injection can speak to a doctor about whether vaccination would still be beneficial.

Who Should Consider an Annual Flu Injection?

Influenza can affect anyone, but some people have a higher risk of severe illness and complications.

Vaccination is especially important for:

• Adults aged 65 and older;
• Pregnant women;
• Young children;
• Healthcare and care workers;
• People living with asthma or chronic lung disease;
• Patients with diabetes;
• People with heart or kidney disease;
• Patients with weakened immune systems; and
• People living with other chronic medical conditions.

The World Health Organization identifies pregnant women, young children, older adults, healthcare workers and people with certain chronic conditions as priority groups for seasonal influenza vaccination.

A doctor can assess your medical history and advise whether the flu vaccine is appropriate for you or your child.

Can the Flu Vaccine Give You Flu?

No. The injected flu vaccine uses inactivated virus and cannot cause an influenza infection.

Some people mistake mild side effects following vaccination for flu, while others may contract a different respiratory virus around the same time. It is also possible to be exposed to influenza shortly before vaccination or before the vaccine has had enough time to produce protection.

These situations do not mean that the vaccine caused the illness.

Is the Flu Injection 100% Effective?

No vaccine prevents every case of illness. The effectiveness of the influenza vaccine can vary depending on a person’s age, health and how closely the vaccine strains match the viruses circulating that year.

However, vaccination can reduce the likelihood of contracting influenza and may lower the risk of severe illness and complications if infection does occur. Seasonal flu vaccination remains the primary method of preventing influenza.

Flu Vaccination During Pregnancy

Pregnant women have an increased risk of complications from influenza and are included among the priority groups for vaccination.

The inactivated flu vaccine is considered appropriate during pregnancy, but patients should always discuss vaccination with their doctor based on their individual health and pregnancy circumstances.

Should Children Receive the Flu Vaccine?

Young children, particularly those under five, may be more vulnerable to serious flu-related complications. Flu vaccination may therefore be recommended based on the child’s age, medical history and risk factors.

Parents should consult their family doctor regarding the appropriate vaccine, dosage and timing for their child.

Flu Vaccine Versus a Common Cold

Influenza and the common cold are both respiratory illnesses, but they are caused by different viruses.

A cold often develops gradually and commonly causes a runny nose, sneezing and a mild cough. Influenza frequently starts more suddenly and may cause significant fever, body aches, exhaustion, headache and a dry cough.

The flu injection protects against influenza. It does not prevent every cold, sore throat or respiratory infection.

Who Should Speak to a Doctor Before Vaccination?

Most people can safely receive an influenza vaccination, but you should first discuss it with a healthcare practitioner if you:

• Have previously experienced a serious vaccine reaction;
• Have known allergies relevant to the vaccine;
• Are currently acutely unwell;
• Have a complex medical condition;
• Are immunocompromised;
• Are pregnant;
• Are arranging vaccination for a very young child; or
• Are uncertain whether vaccination is appropriate.

Your doctor can review your health history and provide personalised advice.

Protecting the Wider Hout Bay Community

Vaccination does more than protect an individual. Reducing influenza transmission can help protect older relatives, young children, people with chronic conditions and other vulnerable members of the Hout Bay community.

Other practical steps include washing hands regularly, covering coughs and sneezes, ventilating indoor areas and avoiding close contact with others while unwell.
