As vaccination campaigns proceed at different speeds around the world, all governments face the same ethical dilemma: how to deal with those who’ve completed their immunization program. The pressure to give back their full personal and social liberties, and to let them contribute in full to the economic recovery will be strong. But states would be unwise to create different classes of citizens.
The vaccines approved so far need two doses to be effective. At least 19 million citizens globally have received both jabs: More than half of them are in the U.S., 5.3 million in the EU and 2.2 million in Israel. The world’s population is slightly less than 8 billion, so the proportion is tiny. However, as the number of different vaccines increases, and drug companies boost production, this number will grow quickly.
