These SARS-CoV vaccines all induced antibody and protection against infection with SARS-CoV. However, challenge of mice given any of the vaccines led to occurrence of Th2-type immunopathology suggesting hypersensitivity to SARS-CoV components was induced. Caution in proceeding to application of a SARS-CoV vaccine in humans is indicated.

God gave me one hell of an immune system. My exwife and kids got e coli from a daycare outbreak - crapping blood and all - I never had anything happen and I cared for them all. Same with flu, has happened a number of times to my ex, I usually dont get it even when we lived together. Just finished my 250 bottle of quercetin and probably wont reup.
