No, OK, I do understand why. But it is a real pain …
Yesterday morning I had my ‘flu jab. I do this every year as (a) I’m now over 65 and (b) I have diabetes so I’m considered to be at “high risk”.
By mid-afternoon yesterday I was feeling rough. Last night I might as well have had ‘flu, I felt so awful — and I was so hot you could have fried an egg on me. (What a nasty idea!) I felt marginally better this morning and luckily I’ve gradually been improving as today has gone on.
Every year follows a similar pattern. 10+ years ago when I first started having ‘flu jabs they would make me feel rough for maybe half a day; on one classic occasion I felt awful for just one hour.
However a few years ago, when the vaccine contained “bird ‘flu” it knocked me out for over a week. Each year since then the vaccination has affected me for at least two full days, usually starting about24 hours after the injection. Consequently I scheduled this year’s shot when I knew I had three four days clear afterwards. It’s just as well I did, although if it has knocked me down for little more than 24 hours this year that’s definitely progress.
Yes, I do understand why this happens. Although the vaccine cannot give you ‘flu (the constituent strains are either live but attenuated or are totally inactive) like all vaccines they stimulate the immune system into producing antibodies — that’s what they’re supposed to do. And it is this reaction of the immune system, which thinks the body is being attacked, which causes the “illness” side-effects. What’s curious is that not everyone get these side-effects; and of course there are a small number of people (eg. those who are allergic to eggs) who cannot have the vaccine (or have to have an expensively produced alternative).
While the side effects are not pleasant they generally only last a day or two, and for my money they are far better than having real ‘flu which could last 2 weeks even without complications.
It’s just a nuisance to have to go through this every year. However until a way is found to produce a reliable “one shot forever” ‘flu vaccine we are stuck with annual injections. The ‘flu viruses are so variable, and they mutate so quickly, that the vaccine has to be changed every year. The game is to pre-guess which strains are most likely to be active during ‘flu season — for the northern hemisphere this guess has to be taken in February for the following winter; that’s because of the time required to produce the vaccine. When the experts guess right the vaccine is maybe 75-80% effective; guess wrong (as happened last year because of a late mutation) and effectiveness may be down at around 10%.
So while having a ‘flu jab is an annual PITA, it is one which for me is worth it. Until we get a universal vaccination, that is.
