I see that the MJC has issued a fatwa of permissibility for the pork vaccine.

Answer

The MJC as well as the NNB Jamiat has issued their haraam fatwas of permissibility for the pork vaccine. One cannot expect any better from these fussaaq and fujjar molvis and sheikhs who halaalize carrion. They are bereft of any Imaani conscience. They devour and feed others carrion, and pork is also on the menu, hence 'halaal' pork vaccine.
