Although many countries are preparing to vaccinate against coronavirus at the beginning of the new year, many health experts do not see the possibility of reaching a ‘hard immunity’ to this global epidemic this year. They attribute this to low-income countries’ uncertainty about vaccinations, lack of confidence in vaccines in many places, and the evolution of the virus. Dale Fisher, chairman of the World Health Organization’s Outbreak Alert and Response Network, told Reuters next conference: ‘We are not going to go back to normal. That’s why we need to reach out to hard immunity and that should be the case in most countries. As a result, we will not see that situation by 2021. News bdnews24.com.
Fischer said some countries may reach a state of “hard immunity”, but they will not be able to return to normalcy, especially when it comes to border control. The World Health Organization (WHO) has said in a statement that it has no plans to sue.
Hard immunity theory says that if 80 to 90 percent of the population in an area is infected with a virus, it must be assumed that all of them have developed immunity to the virus. If that is true, the incidence of the virus will decrease. Now that the vaccine has been introduced, it is possible to give it on a large scale in most countries of the world, through which it is also possible to develop immunity against coronavirus in most citizens. Dale Fisher is talking about that ‘hard immunity’.
Pandu Riono, an epidemiologist at the University of Indonesia, says the “excessive reliance” of some countries’ governments on the vaccine could also lead to danger, as it may not be possible to reach “hard immunity” soon. The Indonesian government thinks vaccination is enough to deal with the epidemic. They have forgotten that it is important to make people aware of the need for testing, publicity and safety, because it will take some time for vaccines to reach everyone who needs them.
More than 90 million people worldwide have been infected with the new coronavirus. The epidemic, which began in China in December last year, has killed 1.9 million people so far. Pfizer-Bioentech, Moderna and Oxford-AstraZeneca vaccines have been introduced in the United States, Singapore, the United Kingdom and several countries in the European Union. Indonesia and India are also set to launch large-scale vaccinations in the next week. Developed countries are at the forefront of the ticker line. The World Health Organization (WHO) has warned that low- and middle-income countries are still unvaccinated.
