In a March 13 interview, the British government’s chief scientific adviser Vallance said the goal of the U.K.’s fight against the epidemic is to create “herd immunity” in society as a whole, rather than to suppress the epidemic altogether. What is herd immunity? Herd immunity means that the majority of people in a population are immune, so that epidemics will not be prevalent in that population. What is the percentage of infection needed for herd immunity? If we count 60 million people, there will be more than 40 million people infected, and the WHO mortality rate is about 3.4%. In other words, the intention is to sacrifice one to two million people in exchange for herd immunity, thus achieving the purpose of protecting the whole country. This is an incredible idea that leaves the elderly and people with low immunity completely out of the picture. It is a surrender to the disease, and the consequences are unthinkable if this is done. This will not only plunge the people of the country into a crisis of fear, but also the rest of the world, causing other countries to shut down their dealings with them. Not to mention the success, it is still a question of whether the supply of materials and energy can be maintained. Richard Horton, editor-in-chief of the academic journal The Lancet and a Fellow of the Royal College of Physicians and the Academy of Medical Sciences, took to social media to say, “This is another major mistake. The UK response needs to learn from the experiences of China and Italy, and not just be based on what is happening in the UK at the moment. It is simply incredible that the government seems to be ignoring the most important evidence from elsewhere.” And WHO spokesman Yasharevich, when asked in an interview what countries with a surge of cases should do, stressed: No country can use ‘powerlessness’ as an excuse to get down on itself. Many countries are going through the same test that China has previously endured. China, South Korea, Singapore and other countries have approaches that others can refer to. With most countries around the world still on guard and a vaccine still to be developed, the UK’s decision to make a ‘herd immunization’ could affect not just the health of the British people, but the lives of humans around the world. In the worst case scenario, the efforts of some countries may be in vain, and this includes China. The right way to boost immunity At this point, the people of the country to fight the virus, in addition to cooperate with the national policy, should actively improve their own immunity. Chen Huan, director of the Weight Loss and Diabetes Surgery Health Management Department at Youdao Doctor Group, reminds us to do the following: 1. Do more aerobic exercise. Proper exercise can strengthen the body’s immune system, and immunity is the most powerful weapon against the virus. 2, early to bed and early to rise. High-quality sleep can promote the body to produce sleep factor, strengthen the liver’s detoxification ability. 3, a balanced diet. Protein can promote the synthesis of antibodies, fruits and vegetables containing vitamins and minerals can improve the body’s immune function. 4, reasonable weight loss. Obese people belong to the group of low immunity, for obese people, weight loss is the most suitable way to improve immunity.
