Herd immunity has been a subject that people all over the world have become familiar with these days, amidst the global crisis triggered by the coronavirus pandemic.
There are all kinds of debates about immunization taking place, and some even said that a vaccine could not turn out to be successful due to the lack of enough immunization in the US. People don’t really seem to be in a rush to get vaccinated, according to the latest reports. It’s been also revealed that people who test negative might still have immunity.
Study performs largest-scale study
Spain performed a large-scale study on the coronavirus which showed the fact that just 5% of the population managed to develop antibodies. This only strengthens the fact that the so-called herd immunity to Covid-19 is not achievable, according to the medical journal Lancet.
These findings showed the fact that 95% of Spain’s population is still susceptible to the virus. As we noted a while ago, herd immunity can be achieved when enough of the population has become infected with a bacteria or virus or vaccinated against it in order to kill its circulation.
The European Center for Disease Control told CNN that Spain’s research seems to be the largest study to date among the studies on the coronavirus undertaken by European nations.
Herd immunity through natural infection
CNN made sure to point out to the fact that there have been similar studies in China and the United States and “the key finding from these representative cohorts is that most of the population appears to have remained unexposed” to Covid-19, “even in areas with widespread virus circulation,” according to a Lancet commentary published along with Spain’s findings.
“In light of these findings, any proposed approach to achieve herd immunity through natural infection is not only highly unethical but also unachievable,” said the Lancet’s commentary authors.
