Amid the outbreak of the Corona epidemic, the World Health Organization has stated that there is no possibility of covid herd immunity in 2021. Herd immunity is when a person develops antibodies against a large proportion of the population against a disease. Depending on the disease, this large part can change its meaning.
Usually, this share can be between 60 and 80 percent. Herd immunity is achieved in two ways:
First - by vaccinating a large part of the population
Second, due to the spread of the disease to a large part of the population
In the case of Corona, the first method is safe, but it requires an effective and safe vaccine. The other way is dangerous because people cannot be left to become sick or die of an epidemic.
Herd immunity is also confusing and scientists have changed their scale about it. American immunologist Doctor Anthony Fauchi was earlier saying that when 60 to 70 percent of the world's population is exposed to infection, it will become herd immunity against the virus.
90 percent of people will be affected by the infection, then herd immunity will come
When the epidemic began to worsen, the figure was 70 to 75 percent. If the graph of deaths from infection worldwide is uncontrollable, then the rate goes up to 80 to 85 percent. Now that many forms of mutations have been detected in the virus in many countries of the world, it is being said that now around 90 percent of the population will be exposed to infection, only then herd immunity is possible.
Vaccine prepared by hard work
Let us know that the global epidemic coronavirus outbreak has been going on for almost a year. After the hard work of scientists, many vaccines have been prepared. In many countries, including the US, Britain, and Russia, people have started getting vaccinated, while the vaccination campaign is going to start in India soon. The countries that made the vaccine included China.
India has approved two vaccines simultaneously. These include Oxford AstraZeneca's Kovishield and Bharat Biotech's Kovaxin. Currently, the vaccination rehearsal continues in the country. Vaccination will start in the country on 16 January.
The United Nations health agency also said that many countries are experiencing extraordinary circumstances with increased vaccine supply bottlenecks, along with an increase in cases of coronavirus infection, and many countries offering a second dose to increase initial coverage Considering delaying.
