The pneumonia jag is not a live vaccine so you can't catch pneumonia from it. It is once only unless you have no spleen or have certain immune-suppressive conditions. It is often given with the annual flu jag and is less likely than the flu jag to give side effects.
There is also a vaccination against shingles available for those between 70-79 (I think) I have had that, again without side effects. My DM and her DS both had shingles in their 70s and were very unwell and in a lot of pain for months. DD had it on her face and around her eyes in her 20s and that was bad enough.
I was offered a one off pneumonia jab with my annual flu vaccination about 3 years ago. No ill effects at all though to be honest the flu jab was slightly more uncomfortable. I continue to have annual flu vaccinations without any difficulty.
My extremely fit 24 year old son developed pneumonia after a chest infection and was seriously ill, some years ago. Standing in A&E watching his SATs drop while nurses and doctors ran frantically towards him is not something I would ever wish to repeat. I am not unfit but am not sure I could have survived that at my age!
My late mother had COPD and was offered the pneumonia jab every winter in her final years. It was very effective and she had no side effects whatsoever.
I had it without problems. BIL has just been diagnosed with pneumonia but because he had the vaccine he is not housebound or seriously ill, proves the injection helps.
Just been told that there is a pneumonia jab available - a one off apparently. Sounds a good idea, but as I sort of believe that when you have a jab such as this, you are likely to suffer a mild form of the illness right away, I can't make up my mind what to do. Anyone willing to share their experiences please
