Will taking the antiviral drugs Relenza or Tamiflu inoculate me?
It’s still unclear if that’s effective, and it is quite costly. [Editor’s note: According to drugstore.com, a prophylactic course of Relenza–10mg per day for 28 days–can cost at least $175 without insurance.] Also, it’s available only by prescription in the U.S., and availability varies from pharmacy to pharmacy and state to state. Some countries don’t allow prophylactic prescriptions; in Mexico, it’s now being controlled by the government.
