Despite the comprehensive and continuous vaccination campaigns around the world against Covid-19, it seems that reaching herd immunity in any country during this period is an elusive dream due to the increase in the number of deadly virus infections.

For example, in the United States of America, nearly 100 million Americans have been fully vaccinated, and Coronavirus infection is at its lowest level there since October 2020, but, despite all this good news, no one is able to determine whether The war against Corona would have already been won by achieving herd immunity, especially as daily vaccination rates have begun to decline, according to thelist.

Besides, it seems that health experts around the world, say the best we can all hope for, is for the virus to be less lethal and to become something that we all have to live with.

Herd immunity
The reason: The goal of herd immunity appears to be very difficult to achieve.

Evolutionary biologist Rustam Antya, who works at Emory University in Atlanta, is one of those who believe that “it is unlikely that the virus will disappear, but we want to do everything we can to make sure it is likely to become a mild infection.”

Also, an epidemiologist, Dr. Anthony Fauci, called for changing the method of the phrase “herd immunity,” and explained: “People were confused and believed that you would never reduce the infection until it reached this mysterious level of herd immunity, whatever that number was. That is why we stopped using herd immunity in the sense. The classic, I’d say: forget that for a second, we have to vaccinate enough people around the world, and the infection will go down. ”

The goals of herd immunity have changed
Originally, public health experts believed that herd immunity could be reached if 60% to 70% of the population received the vaccines, however, this changed because doctors based their assumptions on the original form of the virus.

In fact, the Corona virus has mutated and is expected to be at least 60% contagious of the original virus, in order to reach herd immunity, at least 80% of the population around the world must now be vaccinated, and with some opponents to vaccination, it will be It is difficult to reach the percentage where herd immunity can be achieved.

Doctors haven’t even begun to think about what would happen if the virus continued to mutate to become more contagious, or whether immunized people could infect other people with the virus, however, public health experts have not stopped trying to combat the spread of COVID-19.

As reported by the Australian Broadcasting Corporation (ABC) news, the World Health Organization (WHO) now recognizes that the virus is primarily transmitted through the air and transmitted through infected droplets. They are calling on governments to combat the epidemic by reducing the risk of transmission through the air / it may be It is a bit late for some, but others still see this as a shift in the right direction for the World Health Organization, whose guidance is important for controlling Corona.
