(TNS) - If everything goes according to plan, much of California could come close to herd immunity levels of vaccination by late summer. Within weeks, the effects could be dramatic: very low case rates, people comfortably allowed to gather again, maybe even some looser rules around mask-wearing.
Of course, little about this pandemic has stuck to the plan.
Between the emergence of new coronavirus variants, unreliable vaccine supplies and uneven access to the doses available, it may take months or even years longer than anyone would like to hit herd immunity. It's possible California, the nation and the world may never get there.
