Every year, as influenza season approaches, we hear a familiar question:
“I took the flu vaccine last year. Do I really need it again?”
It is a reasonable question.
For many vaccines, we are accustomed to receiving a course of doses and considering ourselves protected for a long period. Influenza is different.
Influenza viruses continue to evolve, and the protection provided by vaccination can decrease over time. This is why influenza vaccines are reviewed and updated regularly to provide protection against the strains expected to circulate during the coming season. WHO monitors influenza viruses globally and makes recommendations on vaccine composition, while UAE health authorities consider local epidemiological and virological information when determining the appropriate vaccination approach.
This is also why influenza vaccination is recommended every year, rather than being treated as a one-time vaccination.
Influenza Is More Than a Bad Cold
For many healthy people, influenza may mean several uncomfortable days of fever, body aches, cough, fatigue and time away from normal activities.
For others, however, it can be considerably more serious.
Influenza can lead to complications and hospitalisation, particularly among people who are more vulnerable because of their age, pregnancy, medical conditions or immune status. WHO identifies pregnant women, young children, older adults, people with chronic medical conditions and people with immunosuppressive conditions or treatments among those at greater risk of severe disease or complications. Healthcare workers are also an important priority because of both their exposure and their contact with vulnerable patients.
That is one reason influenza vaccination is not simply about avoiding a few days of feeling unwell.
It is about reducing the risk of influenza and, importantly, reducing the likelihood of severe illness and complications. Current CDC guidance notes that vaccination can also reduce the severity of illness in people who become infected despite being vaccinated.
Who Should Consider Influenza Vaccination?
DHA guidance recommends routine annual influenza vaccination for people aged 6 months and above who do not have contraindications. Current CDC recommendations similarly support annual vaccination from 6 months of age, with particular importance for those at higher risk.
Particular attention should be given to:
- Pregnant women
- Adults aged 65 years and above
- Young children
- People living with chronic medical conditions
- People with weakened immune systems
- Healthcare workers and those caring for vulnerable individuals
- Workers who live in campuses
- People working in open offices
- Teachers
- Students
The appropriate vaccine may depend on a person’s age, health status, previous reactions and other clinical considerations. Vaccination should therefore always be provided following appropriate clinical assessment.
When Is the Best Time to Vaccinate?
Timing matters.
DHA guidance advises that influenza vaccination should ideally be offered during September or October, although vaccination can continue later in the season while influenza viruses are circulating and suitable vaccine remains available. CDC guidance similarly identifies September and October as appropriate vaccination months for most people.
This timing is useful because protection is not immediate.
It generally takes approximately two weeks after vaccination for the body to develop the immune response that provides protection.
So, rather than waiting until influenza is already circulating widely around us, vaccination is better considered as a preventive step taken ahead of the peak season.
Why Does This Matter in the Workplace?
This is where influenza also becomes relevant to Occupational Medicine and workplace wellbeing.
Workplaces bring people together.
An employee may come to work before realising they have influenza. Others may continue working despite mild symptoms. Shared offices, meetings, transport, accommodation and frequent interaction between colleagues can all provide opportunities for respiratory infections to spread.
WHO notes that seasonal influenza epidemics can contribute to significant workplace and school absenteeism and productivity losses.
For an organisation, therefore, influenza is not only an individual health issue.
It can mean employees being absent at the same time, disruption to teams and operations, and increased risk for colleagues who may be more vulnerable to complications.
A workplace influenza vaccination programme can form one part of a broader preventive-health strategy.
It does not eliminate every influenza infection, nor should vaccination replace basic infection-prevention measures.
But it provides organisations with a practical opportunity to make prevention easier and more accessible to their workforce.
Vaccination Is Only One Part of Prevention
The familiar measures still matter.
Regular hand hygiene, covering the mouth and nose when coughing or sneezing, avoiding close contact with people who are unwell, avoiding touching the eyes, nose and mouth, and staying home when sick all help reduce transmission.
Vaccination works alongside these measures, not instead of them.
And perhaps that is the simplest way to look at seasonal influenza prevention:
Do not wait for influenza to arrive before thinking about it.
For individuals, this means considering vaccination at the appropriate time and taking sensible precautions during influenza season.
For organisations, it means considering how preventive measures, awareness and access to vaccination can support the health of the workforce before absenteeism and illness become a workplace issue.
