The population of the United States is approximately 326 million. Vaccinating 80% of the population (the current estimate to reach herd immunity through vaccination) equates to roughly 262 million people. To date, 2.6 million people have received an initial dose of the vaccine (mostly the Pfizer version), i.e. about 1%. As of yesterday Happy Wife is in that count.
At this rate, reaching herd immunity via vaccination would take ten years. Clearly, a very different nationwide deployment model is going to have to be implemented if we’re going to “return to normal” by summer or fall of 2021.
