The world's top ten virologists and epidemiologists say people who have not been vaccinated against coronary heart disease are now at the highest risk.They say its delta type is more capable of infecting people with two doses of the vaccine than with the onset of the coronavirus.

According to the United States, 83 percent of newly infected people are infected with delta. That is why the United States is not lifting the travel ban at the moment.

In addition, the Biden administration is considering making masks compulsory again. Antonio Faucci, an infectious disease specialist in the country, said reluctance to get the corona vaccine had led to a rise in corona infections in the United States.

Delta type has also spread in Singapore. Three-quarters of those infected are vaccinated. Meanwhile, Israeli health officials say 60 percent of those who have recently been hospitalized with covid have been vaccinated.
