Dr. Ashish Ja for herd immunity in the United States



If you are concerned after reading that public experts say that the United States is unlikely to reach herd immunity with COVID-19, Dr. Ashish Ja has a message for you.

“This is not tragic,” the dean of Brown University School of Public Health wrote on Twitter on Monday.

The doctor said many did not understand the recent situation New York Times article which examines experts’ predictions of the immune herd threshold in the United States – the point at which enough Americans would be protected from the virus to make the spread of the disease from person to person unlikely. Public health experts told the publication that herd immunity was not possible in America for the foreseeable future and perhaps never. They speculated that instead of disappearing from our lives, COVID-1

9 is likely to become a manageable threat that will circulate for years to come, depending on how much of the nation and the world is vaccinated and how the virus itself evolves.

Ja, who was not interviewed for Times history, share the key points of the article. He stressed that although the herd immunity threshold for COVID-19 is higher than previously expected, improving access to vaccines and opening photos for children will help improve the nation’s path to the target rate.

“We will have to look at options, vaccinate the world, continue testing, etc.,” he wrote, adding, “It’s all manageable. We will return to a new balance, as we do with many viruses. And COVID will not dominate our lives. And this is important. “

He also added that the herd’s immunity “is not an on / off switch”, so even if the threshold predicted by experts of 80 percent is reached, the disease will not disappear.

“With the onset of summer and autumn, we can’t help but hit herd immunity,” Ja wrote. “But the number of infections will be low. Vaccinated people will be mostly safe. And with better treatment, infections can become less problematic. And life will return to a recognizable norm. And that will be good. “
