Want a COVID booster? Maybe you should pay for it.

Though disheartening, the emerging consensus that the COVID vaccines offer declining immunity is hardly surprising. Some vaccines, such as those for polio, do offer long-term immunity; in contrast, influenza shots have become an annual ritual in many households. The possibility that COVID vaccines would require an annual booster has always been on the table. With a fourth COVID wave crashing on the borders of most provinces, the urgency of offering boosters appears to be growing.
