There is now a strong consensus among scientists and public health experts that the United States will fail to achieve a state of mass immunity against SARS-CoV-2, at least for the foreseeable future. Experts tend to conclude with slow vaccinations that the virus will not disappear in the United States, but it will be a “manageable” threat in the next few years. The New York Times reported in a new article.
Collective immunity refers to a condition in which a high percentage of people in a given community are immune to infection so that the infection cannot spread. In the case of a coronavirus infection, immunity may be the result of vaccination or infection, but it is not clear how many people have the protection needed to stop the infection. At first, epidemiologists spoke by 60 to 70 percent, but later on, higher estimates began to appear.
In the United States, 32 percent of the population currently has vaccinations against COVID-19, for example, Ashish Jha, dean of the School of Public Health at Brown University. BelievesThat about 60 percent of the population could actually have “some immunity”. However, in a country of more than 330 million people, tens of thousands of cases are still increasing daily, while the vaccination rate has been declining for more than two weeks. Around mid-April, the CDC reported an average of more than 3.3 million doses taken daily, and today the index is below 2.5 million.
Experts: The virus will continue to kill
According to the New York Times, the persistent reluctance of some Americans to vaccinate and the spread of novel coronavirus mutations now lead to an expectation that the United States will evade herd immunity for a long time to come. “Instead, it concluded that the virus is likely to become a manageable threat that will occur in the United States for years to come and continue to cause hospitalizations and deaths, to a much lesser extent,” the newspaper said.
“It is very unlikely that the virus will disappear,” said evolutionary biologist Rustam Antia of Emory University in Georgia. “But we want to do everything we can to increase the chance that it will not become a very dangerous infection,” he said.
To reduce the severity of the expected “waves” of infection, experts say it is necessary to continue to vaccinate the population, especially the elderly and groups with other risk factors. High immunization coverage in these segments of the population may keep hospitalization and mortality balance relatively low even after quarantine measures are launched.
The shift in the thinking of the professional public is also reflected in the statement of government epidemiologist Anthony Fauci, who advises US President Joe Biden on combating COVID-19. “We have stopped using the term collective immunity in the classic sense,” he told the New York Times. He added: “I say: forget it for one second. If you vaccinate enough people, the infection will disappear.”
Polls show that about 30 percent of adults in the United States still refuse or reserve Covid-19 vaccines. During a recent inquiry about today’s results looking at The Axios website, 14 percent of respondents said they would not receive the vaccine, and 21 percent are awaiting a decision.
