Why you should book your flu and covid jab together

Flu jabs might not be at the top of everyone’s to-do list, but protecting your people and your business should be. And if you’re booking your workplace flu programme, it’s smart to think double: flu and Covid.

With higher-than-expected demand for both the flu and updated Covid vaccines, some suppliers are already reporting limited availability. Combining flu and Covid vaccinations into one workplace clinic is the most efficient way to protect your team and your business from the two biggest seasonal health threats.

Flu and Covid-19 haven’t gone anywhere. Both viruses are expected to co-circulate during the 2025/26 winter season, especially in indoor workplaces where people spend long hours together. Offering both vaccines in a single appointment helps ensure your team is protected from both threats before the peak hits. According to the latest GOV UK data, Covid cases rose by 20% in the last week of September, with early signs of an uptick in flu as the season gets underway (Gov, 2025).

Co-infection with flu and Covid can happen and it’s not something you want your team dealing with during the busiest months of the year. One common concern is whether getting both jabs at once is “too much” for the immune system. It isn’t. A study published in The Lancet confirmed that co-administering flu and Covid vaccines is safe, effective and does not reduce the immune response to either jab (PubMed). So yes, we recommend two jabs, one appointment.

From an organisational point of view, a combined flu and Covid vaccination clinic is a no-brainer. It means:

  • A single visit
  • Less time away from desks
  • Easier scheduling
  • No need to send multiple reminders or manage two booking systems. Plus, it improves uptake. Employees are more likely to get both when it’s quick, convenient, and all in one go.

The cost of absenteeism continues to rise, and preventable illnesses like flu and Covid are major contributors. According to Verve Healthcare, UK employers lose up to £702 per employee each year due to absenteeism, much of it linked to illnesses that vaccination can help prevent (Verve Healthcare, 2025). Running a combined vaccine clinic is one of the most effective ways to reduce that cost.

It also sends a clear message: your business cares about health, safety, and staying operational through the most unpredictable months of the year. Whether your team is on-site, hybrid, or split across multiple locations, we can help design a solution that works for you.

Protect your people. Protect your productivity.
