I was checking my travel paperwork for my forthcoming holiday to Mexico when I noticed an underlined sentence saying immunise 4 to 6 weeks prior to trip. I had completely forgot , then it crossed my mind if our immune systems are suppressed on pred immunisation could be very dangerous to us. Your experiences please folks do you, don't you , only certain ones. Sorry to keep throwing hand grenades so close to the holiday session , but some country's immunisation is a must. Question is which ones ?
