To deal with the "pestilences" (Matthew 24:7), forced vaccination and banning unvaxed people is an attempt at an impossibility. The Bible predicts that even if everyone was vaccinated, things are just going to get worse. These are the last days in which everything is going to have no real solution and will continue to fall apart until they enact religious laws believing finally that these things are from God. But even that will not suffice because there will always be those "that keep the commandments of God, and the faith of Jesus" (Revelation 14:12). And so the final step will be "that as many as would not worship the image of the beast should be killed" (Revelation 13:15).
