Being sick is a negative thing. Sometimes the effort, cost and pain of taking a preventing shot at a medical clinic might be a rational investment.
How about living in a country with Sharia law? What freedom and rights does not exist there, that exist in a non-Sharia country? There are many. Equal rights for women about inheritance, punishment for adultery, choice of clothing. Non-Muslim extra tax is a discrimination of non-Muslims. The list is probably longer. For more information, study Daniel Pipes website.
Is there a shot in the arm that might prevent this. Are there freedoms and rights in the non-Sharia country that may be taken away in a way that prevent Sharia from replacing the existing laws? Which of these rights and freedoms would be worth taking away? Are dictatorships, like China, able to supress Islamization? Would you prefer living in a Sharia-free China or a Sharia-ruled Western country?
There is a policy that more or less take away the risk of Sharia without breaking any rights or freedoms. That is to reject immigrants and refugees that are Muslim, on one hand, and on the other hand taking in non-Muslim refugees and immigrants at a rate that prevents the rate of Muslims in the country from increasing. One disadvantage with this method is that moderate Muslims that are escaping Sharia from Sharia-ruled countries are declined help, which would be heart-aching to do.
The rational person strives for a future and use means to do this that are optimal.
