Why can't we vaccinate faster?

In my experience, American public health experts place too little trust in their patients. They assume many will fail to get their second doses or will prematurely stop taking precautions.

In normal times, that might be understandable. But during epidemics, most people are highly motivated to save their lives and those of their children and parents. They readily follow instructions like “come back in four weeks.”

The easier you can make it for them — centralizing appointment scheduling, giving out Metro cards or taxi vouchers, letting churches or other social organizations book bloc appointments for members — the better the chances of success.

Striving for perfection saps that.
