Herd immunity to CoVID-19 not yet reached this year?
More than 90 million people have fallen ill with CoVID-19 since the outbreak of the coronavirus pandemic, and for 1.94 million it has proved fatal. And while China has managed to resolve the crisis quite smoothly, the United States and Europe are not doing so well, and now we have to contend with a new strain, the so-called British, which appears to be more infectious. Therefore, the only effective remedy seems to be the vaccination that will achieve herd immunity, provided that about 70% of the population will decide to do so. This is problematic for at least two reasons, firstly, some people do not want to vaccinate, and secondly, we still have problems with the availability of vaccinations.
