Antigen bomb

An antigen bomb was improvised by Captain Kathryn Janeway to distribute an antigen to the macroviruses invading in 2373. 
Attaching a canister of the macrovirus antigen to a grenade, Janeway tossed the resultant bomb into holodeck 2 where she had managed to lure the macroviruses, destroying them (although causing heavy damage to the holodeck in the process). ()
