“The vaccine does not stop disease spread after a certain number of months,” says Dr. Jay Bhattacharya, a professor of medicine and health policy at Stanford University. Even if children were all vaccinated, COVID-19 would continue to spread among the population.

“We can try to restructure our societies essentially around the prevention of a single infectious disease forever … Or we can live our lives relatively normally, using the technologies we have to protect the vulnerable. Those essentially are the two broad choices we face as a society,” says Dr. Bhattacharya.
