I hadn't known that there was a vaccine for pneumonia (which I barely know how to spell). But there is.
I was at the local clinic for a routine inspection, and the nurse said "I see you haven't had a pneumonia jab." "No, I haven't. Should I?" "Yes"
So I rolled up my sleeve, she gave me a jab, and it was as simple as that.
I wasn't vaccinated because I hadn't known it was possible. ome people deliberately avoid getting their children vaccinated against, for example, measles, because they don't understand how it works, why it works, and why it's a good idea. I'd say "Darwin", but this isn't them, it's their children.
Ask your GP about the pneumonia jab.
