Drive Workplace Flu Vaccination Uptake: HR Comms Guide
Quick answer: Driving workplace flu vaccination uptake is a four-stage HR comms job: announce four weeks out, address objections two weeks out, run reminders the week of clinic, then send a thank-you and second-chance pathway after. In Aitor Aspiazu’s experience running corporate programmes for over a decade, around 35% of a workforce — roughly one in three employees — typically take up the offer.
Why Workplace Flu Programmes Need Active Promotion
A workplace flu vaccination programme rarely fills itself. Without active comms, employees forget the date, miss the window, or assume the offer is for someone else. The result is wasted vaccine doses, an underwhelming clinic, and a Finance team asking why next year’s budget should fund it again.
“In my experience running workplace flu vaccination programmes for over a decade, average uptake is around 35% — a good rule of thumb when planning is to assume one-third of your workforce will take up the offer.”
— Aitor Aspiazu, Corporate Care’s Founder and Chief Nurse Consultant
Strong HR comms can lift uptake five to fifteen percentage points above that baseline. The four-stage timeline below is the playbook we use across our 15+ years of Australian and New Zealand corporate programmes.
Influenza is a serious respiratory illness that drives workplace absenteeism. The Australian Immunisation Handbook notes that vaccinating employees can result in workplace benefits such as increased productivity and reduced absenteeism. For at-risk groups — adults aged 65 and over, immunocompromised employees, pregnant staff, and people with chronic conditions — the flu can also cause hospitalisation.
The Four-Stage Comms Timeline
Treat the rollout as a four-stage campaign, not a single announcement email. Each stage targets a different objection or behaviour.
T-4 weeks — Announcement
Open the campaign with a senior-leader endorsement email to all staff — from your CEO, Managing Director, Chief People Officer, Head of HR, Head of Health and Safety, or whoever in your senior team will sign for the programme. Two paragraphs is enough: why the programme matters, when the clinic is, and how to register. Pair it with an intranet post and a brief to people leaders so managers can answer questions in their team meetings the same week.
T-2 weeks — Objection-handling
Two weeks out, shift the comms from “what” to “why”. Put up an FAQ poster in the kitchen and toilets, send manager talking points to your line leaders, and post a short Q&A on your intranet. This is the stage where employee concerns get addressed before they become reasons to skip the clinic; see the common objections section below.
T-0 — Clinic week reminders
The week of the clinic, lean into reminders. A registration push email on Monday, a day-before SMS or Slack/Teams message, and a morning-of nudge for people who haven’t signed up yet. Walk-ins should be welcome. Many employees decide on the day, and a “no booking required” line in the comms removes the last friction point.
T+1 week — Thank-you and second-chance pathway
After the clinic, send a thank-you email to everyone who attended and a separate second-chance pathway for non-attendees. Flu vouchers let employees who missed the onsite clinic redeem their shot at a local pharmacy on the company’s tab, without a second clinic day. This single follow-up step is what lifts uptake the most in our experience.
Sample Employee Announcement Email
Copy and adapt this template for your T-4 weeks announcement. Send it from your senior endorser — CEO, Managing Director, Chief People Officer, Head of HR, Head of Health and Safety, or another visible leader your staff recognise. Senior endorsement is the single biggest signal that the programme matters.
Subject: Free flu vaccinations for all staff — clinic on [date]
Hi team,
Flu season is around the corner, and we’re running a free workplace flu vaccination clinic on [date], in [location], from [time]. Every employee is welcome. It takes about five minutes, and the company covers the cost.
Why it matters: getting your flu shot is a quick way to look after your own health this winter and to help keep our team well through the busy months. If you can’t make the onsite clinic, we’ll share a flu voucher pathway so you can get your shot at a local pharmacy instead.
To register: [link or “no booking needed — walk in on the day”].
If you have questions about the vaccine itself, the clinic team will be on hand to answer them, and your GP is always a good second port of call.
Thanks,
[Senior leader name — CEO, MD, Chief People Officer, Head of HR, Head of H&S, or your endorsing leader]
Aitor’s 35% rule of thumb above is a useful planning baseline — if this is your first programme and you don’t have site-specific data, plan capacity for roughly one-third of headcount. Strong comms (the four-stage timeline above) can lift the figure further.
Common Employee Objections (and How HR Can Address Them)
Five objections come up in nearly every workplace programme. The HR job isn’t to play doctor. It’s to give employees a short, sensible response and a place to read more if they want detail.
“The shot gave me the flu last time”
Many people who feel under the weather after a flu shot are responding to the immune response, not flu itself. The vaccine cannot give you the flu. For the science of why this happens, point employees to our explainer on why you may feel sick after your flu shot.
“I never get the flu”
Not having had it before doesn’t mean you’re immune; it means you’ve been lucky so far. The maths plays out across a workforce of any size; some people who have never had it will get it this year. For more on this, see our post on common workplace flu misconceptions.
“Side effects are bad”
For most healthy adults, mild soreness or fatigue for a day or two after the shot is the most common reaction. That’s the immune system doing its job. For the full breakdown of what’s normal versus when to call your GP, employees can read our post-vaccination side effects explainer.
“I’ll get vaccinated at my GP”
That’s fine. Onsite is the convenient option, but the goal is uptake, not attendance. If a colleague prefers their GP, encourage it; just ask them to confirm they’ve had the shot so you can track participation. For staff who want to use a local pharmacy outside the onsite clinic window, point them to the voucher programme.
“I’m pregnant or immunocompromised — should I?”
For at-risk groups — pregnancy, immunocompromise, age 65+, chronic conditions — the flu vaccine is recommended every year, and is often free under the National Immunisation Program. The clinical detail is best discussed with the employee’s own GP; the HR job is to encourage the conversation rather than answer it. For the post-vaccination experience side, our side effects explainer is a useful read.
Arranging the Onsite Clinic
Once you’ve nailed the comms, the operational side — vendor selection, scheduling, room setup, AIR reporting — is the next job. We’ve covered that in detail in our step-by-step planning and setup guide. The points below are the operational essentials that interact directly with your comms plan.
Get senior management involved
Position flu vaccines as a must-have for the business, not a nice-to-have. Senior leaders who attend the clinic first set the tone for the rest of the workforce far more than any poster or email can.
Assign a flu coordinator
One named coordinator (or a small team) who owns the calendar, the registration list, the day-of running order and the AIR reporting. Pull in workplace safety and occupational health colleagues if you have them.
Choose a vaccination provider
Most workplaces use an external provider that handles the nurses, vaccines, consents and AIR reporting. If you also want a flu voucher pathway for remote, hybrid or missed-clinic staff, look for a provider that does both. The comms is simpler when one team handles the whole programme.
Run the clinic in business hours
Employees attend the onsite flu vaccination clinic during their shift, on the clock. Off-the-clock clinics depress uptake. The convenience signal flips, and employees see the offer as something they have to give up time for.
Offer to family members
Where the budget allows, extending the offer to employees’ immediate family is a strong retention signal. Family members can attend the clinic in person or use vouchers at their local pharmacy.
Plan a clinic room that respects privacy
A single quiet space with a curtained or partitioned area for the consult and injection. Check current Safe Work Australia guidance on shared-space ventilation and seating before signing off the room.
Cover staff who can’t attend onsite
For sites where an onsite clinic isn’t possible, give employees an hour off work to visit a local pharmacy or run the flu voucher campaign. Staff search for their local pharmacy at fluvouchers.com.au and the company is invoiced directly. New Zealand workplaces follow the same model; see our New Zealand programme page for the local pricing and provider list.
Bottom line
Promotion is a four-week comms job, not a one-email announcement. Aitor’s 35% benchmark is the floor, not the ceiling; strong comms can lift uptake five to fifteen percentage points above it. Treat the announcement, the objection-handling poster, the clinic-week reminder, and the thank-you-and-second-chance email as four separate jobs, not one. That’s the entire playbook.
Run a workplace flu programme that actually fills the clinic.
