Covid-19 defense: CNN analysis suggests 12% – and a third of the U.S. population – may currently have little protection against Covid-19.

U.S. Department of Disease Control and Prevention About 6% of the U.S. population is vaccinated against Covid-19, according to recent data from the Centers for Disease Control and Prevention. About 20 million people have received at least one dose of the two-dose method – which trial data show may provide partial protection against the virus – and more than 3.8 million people have been fully vaccinated.

Studies show that people who recover from Covid-19 are more likely to be immune to the virus over a period of time. About 25 million cases of Covid-19 have been reported to the CDC, with about 8% protecting against Covid-19.

However, the CDC estimates that U.S. Only a fraction of the total Covid-19 cases are reported in. The latest estimates show that the total number of cases in December was over 83 million. With 5 million or more cases reported in January, about 88 million people – U.S. More than a quarter of the population – after recovering from the infection – can actually be protected from Covid-19.

Experts say people who already have Covid-19 should still be vaccinated. CNN No. Chief Medical Correspondent Dr. According to Sanjay Gupta, the immunity you get from the Covid-19 contract lasts for a certain period of time, but the nature of the vaccine should give immunity for a long time.

CNN estimates of current defense against Covid-19 do not take into account any potential overlap in people who can be considered both vaccinated and infected.

With at least one vaccine dose administered to about 1% of the population and possibly a quarter of the population is immune after infection, as many people in the U.S. may be at least partially protected against covid-1 at present.

That said, trial data show that a single dose of the vaccine provides only partial coverage. And while some studies have found that the immunity to covid-1 to last for years after infection, others have found that it can weaken after only five months.
