THE flu, otherwise known as influenza, is not just a “bad cold”. It is a highly contagious virus that can lead to serious complications, hospitalisation and even death, particularly in vulnerable groups of people. Early preparation, including timely vaccination, remains one of the most effective ways to reduce both individual illness and community spread.<\/p>\n
Pharmacists are commonly asked, “If I had the flu shot last year, why do I need another one?”. The short answer is that influenza viruses are constantly changing.<\/p>\n
There are multiple strains of influenza viruses, but the most significant are influenza A and influenza B. These viruses mutate frequently and as a result the immune protection from last year’s vaccine may no longer be effective against this year’s circulating strains.<\/p>\n
As a result, every flu vaccine is reformulated annually to match the strains that experts predict will circulate during the upcoming season.<\/p>\n
Twice a year, the World Health Organisation (WHO) makes recommendations on which influenza strains should be included in the vaccine. One recommendation is set for the Northern Hemisphere and one for the Southern Hemisphere, including Australia. Australian vaccines are formulated specifically for our flu season, which typically peaks from June.<\/p>\n
In Australia, community pharmacies, like your local Direct Chemist Outlet (DCO), generally start receiving flu vaccine stock from mid-March through to April, depending on the manufacturer and distribution schedules.<\/p>\n
This timing aligns with national immunisation recommendations, which advise vaccination from April onwards, before flu activity increases.<\/p>\n
While annual flu vaccination is recommended for everyone aged six months and over, it is especially important to plan early if you:<\/p>\n
Are aged 65 years or older<\/p>\n
Are pregnant or planning a pregnancy during flu season<\/p>\n
Have chronic conditions such as asthma, diabetes, heart disease or immune compromise<\/p>\n
Live or work with vulnerable individuals<\/p>\n
Work in healthcare, aged care, childcare or other high-exposure settings<\/p>\n
If you are thinking about the flu season before it arrives, you are already taking the right first step.<\/p>\n
Speak with your local DCO pharmacist early to discuss vaccination options and ensure you are protected for the season ahead.<\/p>\n
