Ok, so I'm not perfect.

But Franics, please use a more authoritative resource than a corporate website which does state this by the way
"TAMIFLU is not a substitute for the flu shot; vaccination is the first line of defense for flu protection."
Granted, there is no serum for the Swine. I would trust Wiki more than the Tamiflu website. Although Wiki isn't perfect either
http://en.wikipedia.org/wiki/OseltamivirBut I will restate strongly, the first line of defense is good hand washing. Airborn particles are included in that, even if you don't go everywhere with a mask...which are useless if they are not airtight around your face and filter the size of the virus. So back to square one...wash your hands because protecting yourself from airborn sources is pretty hard as a layman in public settings.
About N95 masks
http://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/n95list1.htmlhttp://www.ph.ucla.edu/EPI/bioter/n95masks.htmlAlthough anthrax spores and smallpox aren't paint chips, the masks do provide protection against bioterrorism, since the most likely used bacterium would be dispersed in particle form, Utgoff says. In fact, the anthrax mail attacks first spotlighted the N95, as office mailrooms scurried for protective gear.
The N95 is made by various manufacturers under different names, from MSA's "Affinity Foldable Respirator" to 3M's "Particulate Respirator." Look for "NIOSH N95" on the package; the "N95" is a government efficiency rating that means the mask blocks about 95 percent of particles that are 0.3 microns in size or larger.
The N95 rating meets the Centers for Disease Control and Prevention guidelines for protection against tuberculosis and anthrax spores, as well as the most foreseeable bioweaponry, which ranges in size from 1.0 to 5.0 microns. So the N95s are more than capable of preventing their inhalation.
Senate Majority Leader Bill Frist (R-Tenn.), a physician and public health expert, upped the masks' visibility even more recently when he advised that people keep a mask rated N95 or better on hand for each member of the family in his book "When Every Moment Counts."
...the mask blocks about 95 percent of particles that are 0.3 microns in size or largerso if the Swine Flu is 0.3 microns or larger, then you are covered... if you want to wear the damn things all day and night
