Xinhua News Agency, Geneva, May 11 (Reporter Ling Xin) World Health Organization experts warned on Sunday that the term “group immunity” comes from the field of veterinary epidemiology and should be used with caution in human infectious diseases like pneopneumonia. Avoid ignoring personal life and suffering.
Michael Ryan, Executive Director of the WHO Emergency Health Program, explained at the regular press conference that day that the term is used in animal husbandry and related decisions are made only from the perspective of the “cruel” economy. , the status of individual animals Not in the scope of consideration. Particular care should be taken when applying the term “group immunity” to scenarios related to human infectious diseases, as this can lead to unrelenting stones that do not place individual life and suffering in the stone.
He said that the concept of “group immunization” is mainly used to calculate how many people in the population need to be vaccinated to achieve the corresponding immunization effect.
When around 60% to 70% of group members are infected and recovered, the possibility of an outbreak of disease will be greatly reduced, this is the so-called “group immunity” effect.
Ryan said preliminary results from epidemiological studies based on serum antibody detection show that the number of people infected with the new coronavirus is not as high as the total population, which is not what some people think: most of the people in the world are infected, the epidemic will end soon and everything can return to normal. In fact, the epidemic is far from over. Those countries that do not have enough anti-epidemic measures or that have not taken any action will suddenly and magically achieve the effect of “group immunization” at the expense of some older people. “This is a very dangerous calculation.”
He expressed his belief that most WHO members are reluctant to make such calculations. A responsible country will appreciate all members of society, will do everything possible to protect the health of all people and, at the same time, guarantee the stability of society, the economy and other fields.
