just been to GP to ask for the ppv 23 vaccine [to protect the lungs],gp didnt know about it he only had details about ppv11[which has similar protection],so it seems its a little known condition that u can protect against,eventually he located it & the occupational hazard was listed @ the bottom of the page ,has anyone else had the vaccine administered,my employee had a hospital visit some years ago as he was experienceing flu like symptoms -these were diagnosed as 'METAL FUME FEVER' [VERY QUICK RECOVERY] NEEDLESS to say i've told him to get jabbed.my workshop & shed is very open with doors permanently open & i have an esab vented mask which i use occassionally however from my contacts it sounds an almost unheard of condition ,maybe this vaccine is a new treatment?
