As mentioned yesterday, the Novel Coronavirus vaccine has been made available free of charge to the whole population and vaccinations have been carried out in many hospitals.

However, many people are not too clear, or the matter is still hesitant, Shanghai Huashan Hospital, director of the Department of Infection Zhang Wenhong yesterday talked about this topic, instant surge on the hot search --

Zhang Wenhong says fear of getting vaccinated is a human problem

More than 300 million views and 30 thousand discussions

"I'm afraid of any kind of vaccine, mainly because of the pain," and "We only care about the safety of the vaccine, not its free cost."

Director Zhang Wenhong，Affiliated to Fudan University,Department of Infection, Huashan Hospital, About the safety of vaccines, What benefit does vaccine have? Hit vaccine how long can tube?

Those who are not vaccinated will suffer

Developed countries are rapidly completing the vaccination and will reopen once they have completed the COVID-19 vaccination.

When the world's big economies such as the United States, alliance countries, Japan and so on are reopened, and our country continues to close, so to the economy and public psychology caused by the impact, will be far greater than the loss of novel coronavirus.

When the door is open, people who have not been vaccinated will suffer and will be very worried wherever they go.

China has produced 5 million doses of Novel Coronavirus vaccine per day

Novel Coronavirus will be permanent

Novel Coronavirus will be a resident virus in the future, always.

For each individual, the reason to get vaccinated is simple: if I get infected in the future, I'll be fine.

The protection rate of our inactivated vaccine against severe disease is more than 90%, and the protection rate against death is nearly 100%. Vaccination at the national level is to stop transmission, from the individual level is not an accident.

Is it possible to reinfect with novel coronavirus after vaccination with coronavirus? Possible.

Vaccination is not 100% protective, but after vaccination, even if the infection may be asymptomatic, or similar to the common cold, small flu, or large flu.

When can the mask be taken off?

We need at least a 70 percent vaccine protection rate to be able to say that we constitute an effective immune barrier.

70% is the minimum requirement, not necessarily enough, because the vaccine protection rate is not 100%; If the protection rate is calculated at 90%, I think the ideal vaccination rate is above 80%, it can be said that we can safely open the door.

If the country vaccinates 5 million doses of vaccine every day, it will take about half a year to reach a 70% protection rate, which is an ideal estimate.

Hit vaccine how long can tube?

The expiration date will become clearer over time, and the duration of the antibody will be available.

After the attenuation of the antibody does not mean that there is no protection rate, we need a year or more to get this data; Many countries vaccinate before us, and their data will come out first.

China will push ahead with the largest mass vaccination campaign

According to the latest information from the joint prevention and control mechanism of the State Council, as of 24:00 on March 22, 2021, China has received 80.463,000 doses of Novel Coronavirus vaccine, with a steady increase in the number of vaccinated people.

At present, more than 100 million Chinese Novel Coronavirus vaccines have been vaccinated at home and abroad, and the vaccines are safe and effective. Next, we will accelerate the promotion of free vaccination for all the people in the country, from high-risk and key groups to the general population, which will be the largest centralized vaccination.

Director Liang Zongan, West China Hospital of Sichuan University and Respiratory and Critical Care Medicine: The vaccination "wind" is coming,Suggest the whole people "follow suit"!

There is no doubt about the efficacy and safety of vaccination

At present, there are 5 types of vaccines in China, including 3 inactivated vaccines, 1 adenovirus vector vaccine and 1 recombinant protein vaccine. Liang Zongan introduced that the safety of the five vaccines is beyond doubt in terms of effectiveness and safety. It is a traditional vaccine with a very standard production process, and the effectiveness of the vaccine in existing clinical studies has also been verified.

Liang Zongan further explained that according to the results of recently published studies, the effectiveness of several vaccines is around 60 to 80 percent, which all reach the range of basic protection effectiveness of vaccines.

However, the effectiveness of the vaccine studied in some places is even higher, such as Turkey, where the effectiveness is more than 90% and the protection against severe diseases is almost 100%. Judging from the existing data and studies, both effectiveness and safety are guaranteed.

"Of course, less information has been published on adenovirus vector vaccines and recombinant protein vaccines, but it is important to remember that clinical studies for vaccines are more rigorous than for any drug, so it is important to remember that as long as they are approved by the state, there is no doubt about their efficacy and safety."

People with allergies should be cautious and careful when inoculating COVID-19 vaccine

In the "Informed Notice of Urgent Use of COVID-19", it is clearly reminded that some people are not suitable for vaccination, such as those who have previously been infected with COVID-19 or those with positive nucleic acid and antibody tests. Why can't these populations be vaccinated?

"China does have strict requirements for the vaccination of the new coronavirus, in order to avoid accidents or serious complications caused by the injection of the vaccine."

Liang Zongan said that when China conducted clinical research on COVID-19 vaccine, people in the [vaccination taboo] group were not in the scope of the study, so these groups would be restricted by the vaccination.

"It's important to note that people with allergies need to be careful when they get vaccinated, because almost all of our vaccines contain protein, which can cause some allergic reactions."

Act quickly!
