The Rule of Seven and getting your Flu jab

Way back in the 1930s, Hollywood film makers came to realise that moviegoers needed to see advertisements for the studio’s films a whole seven times, before they would decide to buy a ticket and go to the cinema. The Rule of 7, as the idea became known, was quickly taken up by advertisers and marketing companies. I’m not sure if the rule still applies today, but for the purposes of this week’s blog, I’m going to assume it does.

I’m on a campaign to persuade everyone to get their flu jab asap. So, I’m taking every opportunity to remind, persuade, and challenge people, to get their flu jab. There are very good reasons for doing so. The ‘flu season’ in the UK has already started, and it has started in a big way. Every day last week there were nearly 1,800 people struggling with influenza in acute hospital beds, 69 of whom were in critical care units.

According to NHS England (NHSE), this is 56% higher than the same week last year and ten times higher than two years ago. The NHSE Chief Executive, Sir Jim Mackey, noted last week that this number could easily quadruple in the coming weeks. People need to get their flu jab, in order to reduce the risk of becoming one of these patients in hospital.

Fortunately, nearly 17 million flu vaccinations have been given this year. However, the population of England is just over 58 million people, and across the UK, over 68 million. Anyone over the age of 65 (and many others, see here) can get a free flu vaccination. If you are not eligible, flu vaccinations cost on average £12. Now if you think that is not a great way to spend your hard-earned cash, consider the story of Steve Collett.

Last Christmas, Steve spent 19 days in a coma after catching flu. He spent 52 days in hospital and has not been able to return to work since due to the long-term consequences of his illness. Like other healthcare workers he was entitled to a free flu vaccination. He chose not to have one, believing himself to be a fit and healthy individual. There were nine to ten days where it was uncertain as to whether Steve would survive, or not. If Steve’s experience doesn’t persuade you to get your flu vaccination, last year there were 7,800 deaths from flu. That is more than double the 3,600 deaths in 2023-2024.

Getting a flu vaccination is the best way to protect yourself. For healthcare professionals like Steve, it not only protects the individual, but the patients they care for. Paradoxically, over the last few years healthcare professionals have for various reasons, been reluctant to get a flu vaccination. This year we have access to more robust data on the uptake of flu vaccinations by healthcare colleagues. The national average uptake level currently stands at just under 40%. The best (Harrogate and District NHS FT and Norfolk and Norwich NHS FT) have both achieved a 61% uptake. Well done to both organisations!

There are other compelling reasons for folk to get their flu vaccination; that is the current state of urgent and emergency care services. A&E departments are already experiencing increased demand. Whilst a third of all people who pitch up have no need for emergency care*, nationally, A&E departments are becoming increasingly busy, as health problems associated with winter begin to rise. They are not great places to be, if you don’t need to be there. Helpfully, last week, NHS England posted a great short film on YouTube entitled 24 Hours Not in A&E’ to try and help folk get help for common health problems rather than pitch up at an A&E department. Getting a flu vaccination will also help you avoid an A&E department attendance for flu.

Finally, this year’s flu mutation, H3N2, is said by the World Influenza Centre to be more infectious and leading to more severe illness and hospital admissions than previous flu viruses. It’s been described as a ‘nastier’ virus than those previously experienced. China is a few weeks ahead of the UK with its flu season. The H3N2 flu virus is already beginning to cause China hospital and other health care services to become overwhelmed. So please, please, if you haven’t already done so, get your flu vaccination as soon as you can. Let’s try and keep each other healthy and safe.


* I was astounded to discover that there were over 200,000 A&E attendances this time last year for non- emergency conditions which could easily have been sorted elsewhere. These included almost 9,000 attendances for itchy skin and nearly 97,000 for a sore throat.
