Όνειρο ήταν και πάει

[Dwarven Blacksmith]

Η Κίνα πιστεύει ακόμα στο όνειρο και λέει ότι με 80% ως το τέλος του έτους θα καταφέρει να δημιουργήσει ανοσία αγέλης. Είμαι εκτός γραμμής

Ας βάλω και μια πηγή σ' αυτό.

China is expected to achieve 80-percent vaccination coverage against COVID-19 by the end of this year and reach herd immunity, Zhong Nanshan, the country's top respiratory expert, said in a virtual speech at a conference under the 5th China-Arab States Expo on Friday.

Achieving herd immunity depends on vaccine efficacy and virus transmissibility, he said.

"The efficacy of China-developed vaccines is about 70 percent, so the country would need more than 80 percent of the population to be vaccinated before establishing herd immunity," Zhong said, adding that China is expected to reach that goal by the end of 2021.

Πάει και η Κίνα.

Wu Zunyou, China's CDC chief epidemiologist:
Ανοσία αγέλης, not gonna happen.

"We previously thought COVID-19 could be basically contained through vaccines, but now it seems that there's no simple method to control it except with comprehensive measures, although vaccines are the most important weapon in curbing the epidemic, including Omicron," the chief epidemiologist said.

Responding to the question whether vaccinating 70 percent of the global population could end the acute phase of the pandemic, Wu said such an assertion is still open to discussion. Ahead of the fourth wave of the pandemic, many countries in Europe have already reached 70 percent total vaccination, and some countries like Germany, France and the UK have vaccination rates above 70 percent, but the occurrence of Omicron with breakthrough cases challenges the concept of herd immunity.

Και για τη θεωρία ότι από το Μάρτιο όλα θα είναι καλά:
(tl;dr θα πέσουν τα κρούσματα προσωρινά αλλά δεν πιστεύει ότι έρθει κανένα τέλος)

By March 2022, a large proportion of the world will have been infected with the Omicron variant. With continued increases in COVID-19 vaccination, the use in many countries of a third vaccine dose, and high levels of infection-acquired immunity, for some time the global levels of SARS-CoV-2 immunity should be at an all-time high. For some weeks or months, the world should expect low levels of virus transmission, the study said.

Wu believes there are some practical challenges to Murray's hypothesis as there are a lot of differences between the novel coronavirus and influenza.

"First, immunity can last up to a year after infection with influenza, while it generally lasts about 3-6 months after infection with COVID-19. Second, although influenza also has variation, its variation is regular, and its variation cycle is relatively long, usually once a year, meaning that this year, its variation will not affect the protection rate," Wu said. "But the variation of COVID-19 is very fast, almost every day."

The pandemic has gone through four waves. Seeing from the past two years, I can say the view that March has become the key point for ending the pandemic is not supported by sufficient scientific evidence, Wu said. "But, from a global perspective, it is possible, and very likely, that the trend will wane in March or for some time to come."

Some Western media reports also said that although Omicron has strong transmissibility, it is less severe compared to other variants like Delta, so people could treat it as a "flu" in a more optimistic way.

However, Wu said that Omicron cannot be a "flu" because it infects a different part of the respiratory tract than the flu (flu infects the upper respiratory tract, while COVID-19 infects the lower respiratory tract). Upper respiratory tract infections rarely cause pneumonia, unless the illness is prolonged.

Outside China, Omicron has a much higher rate in severity and fatality than that of influenza, so it cannot be a "big flu," the expert said.

Some other people also believe that the novel coronavirus can infect not only humans but also animals, so humans may never end the pandemic and have to live with the virus for a long time.
