Since the New Year of 2020, the whole country has been shrouded in the haze of the COVID-19 epidemic. Through the joint cooperation of governments at all levels, medical staff, and all citizens, whether it is closing cities, closing communities, or vaccination, epidemic prevention work has been carried out in an orderly manner. This has also enabled the epidemic to be effectively controlled.
However, just this spring, epidemic counterattacks occurred in many places across the country. A new round of epidemic recurrence occurred in Jilin, Shandong, Shaanxi, Shanghai and other places. However, since most people have received three shots of the new crown vaccine , Therefore, most of the infected people are asymptomatic or have mild symptoms and have not caused too serious losses.
However, due to the recurrence of epidemics in many cities across the country, everyone has questioned the efficacy of the new crown vaccine. Many people are also concerned about whether a fourth shot of the new crown vaccine is needed next? Let’s listen to what relevant experts have to say about the next steps to fight the new coronavirus epidemic.

The scary thing about the new coronavirus
In recent years, as scientists have analyzed the new coronavirus, they have discovered that the new coronavirus can be infected through close contact with gases emitted by droplets such as coughing, sneezing, talking, etc. In addition, it can also It is transmitted through mother-to-child transmission and aerosol . The transmission route is extremely wide, and people of all ages are likely to be infected.
When analyzing COVID-19, Academician Zhong Nanshan said that mucus in the lungs is one of the causes of death. The damage caused by COVID-19 to the lungs is not a one-time fix and then there will be no worries, but there is still the possibility of recurrence, and the damage to the lungs is not It can be repaired immediately, but it may take up to 15 years for the lungs to repair slowly. During these 15 years, if other diseases affect the repair of the lungs, the body's immunity will also decrease.
According to Tong Zhaohui, an expert on the medical treatment team of the Central Steering Group and deputy director of Beijing Chaoyang Hospital, compared with patients with SARS in 2003, one of the several obvious characteristics of patients with new coronary pneumonia this time is: cardiac damage The attack is very severe. Indicator analysis found that the heart's troponin increased at a high rate.
Researchers at Tongji Hospital have found that patients with new coronavirus infection may have kidney damage and suggest that when patients with confirmed infection (especially severe and critically ill patients) are admitted to the hospital, they should pay attention to the patient's kidney damage as soon as possible and use multiple kidneys if necessary. Protective measures are expected to become one of the effective measures to reduce the mortality of critically ill patients.

Is the fourth shot about to start?
Recently, there have been recurring epidemics in many places across the country. Coupled with the emergence of new crown mysterious cloned viruses, more and more people have begun to pay attention to the fourth shot of vaccination. Therefore, the fourth shot of the new crown vaccine is required. ?
Abroad, many countries have started the fourth wave of COVID-19 vaccination, such as Israel, the United States, Germany, Thailand, etc. According to the testing data of medical staff participating in the trial in Israel, one week after the fourth injection, these medical staff had Antibodies increased fivefold.
We are still in the wait-and-see stage as to whether my country will take the fourth shot of the COVID-19 vaccine. Zhang Wenhong, director of the National Medical Center for Infectious Diseases, said in an interview: At present, my country's epidemic prevention and control is relatively good. There is no need to be so anxious about the fourth shot of the vaccine. More international experience can be used as a reference.
Judging from the third booster shot of COVID-19, research on variants, including variants, has conclusively shown that the COVID-19 vaccine is highly effective in reducing severe illness and mortality. It can increase antibody levels dozens of times, minimizing the risk to patients. The seriousness rate is reduced to a minimum.
In addition, everyone is more concerned about the issue of special drugs. Zhang Wenhong, director of the National Center for Infectious Diseases, said that the end of the COVID-19 pandemic has never relied on drugs. This kind of drugs only helps us get out of this pandemic and reduce deaths as much as possible. . The pandemic itself relies on people's own immunity, which is acquired through vaccines or natural infection.
WHO research shows that China's Sinopharm, Feasible and other domestically produced new coronavirus vaccines can prevent the risk of severe hospitalization infection with the Omicron strain . It is expected that the domestic vaccine will be effective in patients infected with the Omicron strain. The protection will last. As long as they are not unvaccinated or high-risk groups, vaccinated people will have a certain degree of immunity.
At present, the third dose of vaccination in our country is still continuing and steadily advancing, and domestic epidemic outbreaks occur from time to time, so everyone still needs to focus on daily prevention and control.

Those who plan to vaccinate, please note that these 9 categories of people may not be suitable for vaccination!
. Those who are allergic to any component of the vaccine, or have had severe allergic reactions to vaccines in the past, such as acute allergic reactions, urticaria, skin eczema, dyspnea, angioedema or abdominal pain.
. Those who have fever, suffer from acute diseases, serious chronic diseases, or are in the acute attack stage of chronic diseases.
. Pregnant women and lactating women, and those who plan to have children within 3 months of vaccination.
4. Those who have a history of convulsions, epilepsy, encephalopathy or mental illness, family history, those who suffer from uncontrolled epilepsy and other progressive neurological diseases, and those who have a history of Guillain-Barre syndrome .
5. Those who have been diagnosed with congenital or acquired immune deficiency, HIV infection, lymphoma, leukemia or other autoimmune diseases .
6. Those who are known or suspected to have severe respiratory diseases, severe cardiovascular diseases, liver and kidney diseases, or malignant tumors.
7. Those who use immune modulators such as anti-tumor drugs.
8. Those with a history of COVID-19 infection.
9. Clinicians or vaccination staff believe that the vaccine is not suitable for the vaccinator.
At this stage, the above nine categories of people are recommended to postpone vaccination of the new coronavirus vaccine. Everyone must make a true introduction to the vaccination staff based on their actual situation to avoid serious consequences.

Even if you are vaccinated, you must take protective measures
Zeng Yixin, deputy director of the National Health Commission, said that even if you are vaccinated against the new coronavirus, vaccinated people must take protective measures. After all, the protective effect of vaccines is not 100%, especially when the current herd immunity has not yet been established. Even if vaccinated, these protective measures will still remain intact to better ensure everyone's safety.
. Wearing a mask
Wearing a mask is an effective way to reduce public cross-infection , effectively reduce the risk of transmission, prevent the spread of the epidemic, and ensure the health of the people. Research shows that if a person carrying the new coronavirus has close contact with a healthy person and both wear masks, the infection rate will be reduced to 1.5%. If neither person wears a mask, the infection rate will be as high as 90%.
, wash hands frequently
absorption is even called the most economical vaccine. On the basis of wearing a mask, maintaining hand hygiene is an important link that cannot be ignored. Through absorption, 80% of diseases can be prevented and diarrhea can be reduced by more than 50%. And 1/4 of respiratory infections , so you must wash your hands properly and maintain hand hygiene to reduce the spread of viruses and bacteria.
. Opening windows for ventilation
Opening windows for ventilation can help reduce the amount of viruses that may exist indoors, and also help exchange indoor and outdoor air. After the outdoor air is diluted, it is almost impossible to bring viruses into the room. When opening windows for ventilation, pay attention to the frequency of ventilation. Ventilate at least 3 times a day, and the ventilation duration is preferably 20 to 30 minutes.
