This year is different, with the likelihood of a world outbreak, and out of stock all round the world. One hospital informed me it's been out of stock for weeks. One private practice ordered 100 earlier and wanted 100 more but got none, and told me the manufacturer had stopped producing, would have no more this year. I'm not looking for one for myself or child because I prefer natural immunisation, but for my father because he's elderly. My husband can get one free for himself through his company but he prefers not to. If you can't get the vaccine, try to take more vitamin C, cod liver oil and do exercises to immunize yourself.
