Catching it and recovering is more effective than a vaccine.  Please study immunology before making comments like that.  I studied it in great detail for 2 of my 6 degrees, so I can tell you with absolute certainty that even if I do catch it again, the antibodies I possess will destroy the second infection immediately with absolutely no problem. Just because you saw something on TV or read about it on the internet doesn't automatically make it true.  Don't blindly follow the lies spouted by the media.  It makes you sound like a fatty screaming about HAES.
