The U.S. was quick off the blocks in its vaccination campaign but its pace has now slackened considerably. Earlier in the year, the world looked on with envy as the U.S. got jabs into arms at lighting speed but by late July, it had only managed to fully vaccinate 48.7 percent of its population. Many of the countries that looked on with envy back in February and March have now surpassed the U.S. in terms of full vaccinations and the list includes Canada (54.7 percent), Spain (54.3 percent) and Germany (48.7 percent) according to Our World in Data.

The current level of vaccination in the U.S. is not high enough to stop the spread of the highly infectious Delta variant of Covid-19 and 48 states saw their case count grow by 10 percent over the past week while 34 percent experienced a 50 percent leap.

According to, Alabama has the lowest rate of full vaccination in the U.S. at just 34.04 percent and it is followed by Mississippi (34.18 percent) and Arkansas (35.95 percent). At the opposite end of the U.S. vaccination league, Vermont has the highest share of fully vaccinated inhabitants at 67.28 percent while Massachusetts, Maine, Connecticut and Rhode Island all have rates of 60 percent or higher.
