US Closing in on 350,000 Daily COVID-19 Vaccine Doses

An original version of this article was published by sister publication Contagion.

The US has administered more than 4.5 million doses of coronavirus 2019 (COVID-19) vaccine to its population as of Monday, January 4, per estimated counts from the US Centers for Disease Control and Prevention (CDC) and University of Oxford.

While discussion surrounding the distribution of recently-authorized two-dose mRNA vaccines BNT162b2 from Pfizer and BioNTech, and mRNA-1273 from Moderna, has focused on the merits of single-dose versus standard administration, the nation has increased its daily vaccination count from approximately 235,000-348,000 in just 1 week.

Presently, the very small countries of Israel and Bahrain are reporting a substantial vaccination count per capita, while the United States improves on a slow rollout start.

Unsurprisingly, among the most vaccinated states thus far are California, Texas, and New York—large, highly populated regions notably affected during various waves of the pandemic since March 2020.
