The Hell Syndrome vaccine is an inactivated vaccine of Hell Syndrome. The vaccine was made by infusing the Hell Syndrome virus with a "weakened" version of the Serum of Purification. Anyone with this vaccine develops targeted and innate immunity to the Hell Syndrome virus. The white blood cells of vaccinated people are also constantly updated to any mutations of the Hell Syndrome virus. Non-overridable.
The vaccine is currently being mass-produced and distributed across the universe.
Nice try, Clorax. But the Death Virus is and will always be superior to your "Hell Syndrome".
