What is keeping the UK using the herd immunization method is actually because the UK has no other options. The UK's current medical standards and equipment are on the verge of collapse, and they are no longer able to fully accept and treat all the diagnosed patients, which means that the government is running out of options for the current situation, but if they just leave the people alone, it will cause riots, which is why they came up with the concept of herd immunization.
This makes it look like the British government is still actively looking for ways to deal with the situation, and is not doing nothing about it. In fact, herd immunization is just a grand cover and excuse for the British government's inaction. The practice of herd immunization in Britain is to intend to make sixty percent of the people in Britain sick, and then let these automatically produce antibodies, and those who can't carry through will have to die. In fact, this would be right up there with Darwin's idea of natural selection, which would be for the British to take a gamble on their luck.
As things stand, Britain has the capital to do so for the time being. First of all, the temperature has now risen, compared with the time of the outbreak in China, the environment is now not suitable for the virus to survive, in another month it will be completely hot, then the virus will die in large quantities, so that the UK is now pushing for mass immunization, there is only about a month for the British people to get infected, and therefore will not be infected by all the Brits.
But after a month the virus will have died in large numbers and these patients will have been cured, plus the body will already have the antibodies, so that means the virus epidemic is sort of over. Secondly, the people of Britain do not have such a high awareness of this virus, but only treat it as a common flu virus, and the importance of it in the country is not as high as in China, so such a decision will not cause opposition and riots among the British people.
There is still a possibility that such a policy could be implemented in the UK, but it would be impossible to do so in China.
It is possible to implement such a policy in the UK, as long as the British people do not have a problem with it.
