US can achieve herd immunity through the summer through vaccinations alone, CNN analysis finds

by

This week, President Joe Biden said the U.S. will have enough vaccine for every adult by the end of May, and a CNN analysis of federal data shows that immunity to herds is probably not far behind.

At the current rate of about 2 million shots per day – the latest average of seven days in doses reported by the US Centers for Disease Control and Prevention – the US can achieve herd immunity through vaccination alone. It will probably be even sooner if individuals who have natural immunity due to previous infection are taken into account.

When will the US achieve herd immunity and what will it look like?

Herd immunity thresholds for Covid-19 are estimates only at this time. But experts generally agree that between 70% and 85% of the population needs to be protected to suppress the spread, a series that dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, recently quoted.

According to the latest data from the CDC, more than 8% of the population – almost 28 million people – have already been fully vaccinated.

If vaccination continues at the current rate, and the two-dose vaccines from Pfizer / BioNTech and Moderna are the only options, 70% of the US population could be fully vaccinated by mid-September.

But the U.S. Food and Drug Administration recently approved the vaccine vaccine for Johnson & Johnson for emergency use, and the company promised to deliver 100 million doses to the U.S. in the first half of the year.

What life is like in countries where Covid-19 vaccination is increasingly a success

At the current rate of approximately 2 million doses per day, including 100 million doses of Johnson & Johnson vaccine, 70% of the U.S. population could be fully vaccinated by the end of July and by 85% by mid-September. to a CNN analysis.

The CDC estimates that more than a quarter of the population may have been infected by Covid-19, which has protected the share of the population to nearly a third. Assuming that there is no overlap between people with natural immunity and those protected by vaccination, herd immunity can be achieved as early as June.

Experts note that some new variants threaten progress, which may reduce the protection of vaccines and promote a degree of natural immunity, and that hesitation against vaccines may also cause limitations.
