At the beginning of the new year, a new coronavirus epidemic swept the world. Since the discovery of the first Omilon variant in South Africa on 9 November 2021, in just two months, Omilon has invaded nearly 150 countries and regions around the world. It has a strong infectiousness and concealment, which has brought great obstacles to the normal life of human beings.
It is worth noting that China has defeated the epidemic in a short period of time with the "zero new crown" policy and the attitude of "zero tolerance" for the virus. However, the cunning virus does not want to disappear from human vision easily. Today, 14 provinces in China have detected cases of Omiclon, whether the need for a fourth dose of vaccine has become an urgently known problem for the people of the whole country, Professor Zhang Wenhong, director of the National Center for Infectious Diseases And director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, explained.
The pandemic is sweeping the world
As we all know, the most effective and concise way to fight the virus is to get the new crown vaccine. At present, many countries in the world have the ability to produce vaccines independently, and people in most countries have been vaccinated with at least two doses of COVID-19 vaccine.
However, there are always countries that have not yet completed vaccination due to various factors, and the United States is one of them. As a typical negative example of the fight against the epidemic, the current epidemic situation in the United States can be called the worst in the world.
As of January 17, the cumulative number of confirmed cases in the United States exceeded 66.99 million, and the cumulative number of deaths exceeded 870,000. Importantly, Omilon cases account for 95.4% of the new cases in the United States, proving that Omikeron has become the mainstream virus in the United States. Fauci, director of the American Institute of Infectious Diseases, pessimistically believes that under the invasion of Omicron, all Americans will not be able to escape. And, given the political differences between the two parties in the United States, most of the American people are not vaccinated. It can be seen that under the wave of the epidemic, the situation in the United States will be even worse.
The same is true in Europe, where the number of new infections in European countries has reached new highs after the abandonment of the "new crown clearance", and all European countries have been reduced to high-risk areas. Although its vaccination rate is slightly better than that of the United States, it still cannot withstand the "offensive" of the epidemic, and Europeans will have to meet many challenges in the future.
Zhang Wenhong gave the answer
At present, 14 provinces in China have reported imported cases of Omi kerong, and a new round of anti-epidemic war is about to start. And when the Spring Festival comes, the difficulty of this battle will increase. Therefore, various localities have issued a series of policies such as "non-essential do not go out" to cope with the tense epidemic situation.
In the context of the Omicron epidemic, the people of the whole country want to know whether to get the fourth dose of vaccine, in this regard, Zhang Wenhong, director of the National Infectious Diseases Medical Center, gave the latest statement on January 15, including studies including variants, which confirmed that the new crown vaccine has a significant effect in reducing severe illness and mortality, especially the third dose of vaccine can increase antibody levels by dozens of times. As for the fourth stitch, he thinks it is too early to say, "There is no need to be so anxious now, and we can have more international experience for us to use." ”
Zhang Wenhong said that in principle, after the next year, whether it is the level of herd immunity, or the immune barrier established through vaccines, or the listing of new crown treatment drugs, it means that "this may be the last 'cold winter'".
