Flu Shots Or Not?
It sounded like a good idea when New York City's mayor,Rudollph Giuliani,advised New Yorkers recently to get a flu shot.After all,20,000 Americans each year die of influenza. And this year in particular,the mayor suggested,getting a flu shot might be an especially good idea, since it could help doctors distinguish between flu and the deadly inhalational(吸入的)form of anthrax(炭疽).How? Both anthrax and flu exhibit strikingly similar symptoms-fever, chills and muscle aches-in the early days of the infection.Physicians would be quick to suspect anthrax in anyone who was vaccinated(接种疫苗)against flu and still developed fever and chills. That would give them a better chance to identify any new victims of terror while their infection was still in its earliest,most treatable stages. Or so the mayor's reasoning went. Unfortunately,there are a couple of problems with his log-ic .For one thing,getting vaccinated against influenza doesn't guarantee you won't get sick .Al-though highly effective,the flu vaccine(疫苗)protects against only the dominant types of the dis-ease and even then does not provide 100% protection.It takes a couple of weeks for your body to respond to the vaccine with a sufficient number of antibodies(抗体).Each year thousands of Americans who get the vaccine nevertheless still get the flu. There are also plenty of reasons you might develop fever,chills and muscle aches that have nothing to do with either anthrax or flu .Indeed,doctors estimate that more than 80%of all flu-like illnesses each winter are caused by other groups of viruses.Getting vaccinated against flu can't protect you against suffering from these other illnesses. In the worst case,asking all healthy adults to get vaccinated could actually have the opposite effect to the one intended,leading to even more deaths if it means we run out of shots for those who are most vulnerable to the infection.Already there have been delays in getting this year's shipment of vaccine to clinics and doctor's offices.Those who should be at the front of the line in-clude folks who are 65 or older,nursing-home residents and adults and children with chronic health problems as well as anyone who cares for or lives with such people .Flu shots are also im- portant for men and women whose immune system is weakened by HIV(艾滋病病毒)or other conditions. The best reason to get the flu vaccine is that it proteets against most flus-not that you're worried about getting anthrax.While inhalational anthrax has killed only five people so far,many more could be at risk from flu-related complications.There's no need to worsen the tragedy by making this year's influenza epidemic any worse. It is not easy to tell anthrax from flu in the early days of the infection. A.Right B.Wrong C.Not mentioned [多选题]申请办理金信家E贷借款人应符合农信机构信贷基本制度,下列____选项正确?
