Argument 3: If someone is healthy right now, why should he, by his own actions, place himself in danger – however remote – just to save himself from a danger that does not exist at this moment, and perhaps will not exist in the future?

Answer: First of all, we said that this vaccination does not pose a remote danger but a danger that is considered halachically negligible. Yet the crux of the matter is that Argument 3 does not relate specifically to the vaccination against swine flu, but to any vaccination. For that matter, arguments 1 and 2 relate as well to all vaccinations. Thus, Rabbi Yisrael Lipschitz, the author of Tiferet Yisrael on the Mishnah, has already dealt with this as it refers to Mishnah Yoma chap. 8 #3, regarding the vaccination against the Black Plague. He proved from several Talmudic sources that a person is allowed, by his own actions, to place himself in low-level danger of 1/1000 in order to save himself, in the future, from a high danger. As noted above, swine flu poses a serious danger. Therefore, those groups marked by the physicians as meant to receive the vaccination should not relate to it lightly.
