How did the domestically produced COVID-19 vaccine come about, which is free for all?

On the last day of 2020, the motherland gave us a New Year’s gift? The domestic new crown vaccine has been approved for sale, and the vaccination is free for all. How did the domestically produced COVID-19 vaccine, which is available to everyone free of charge, come about?

From free medical treatment for all infected people to free vaccination for all, saving everyone and not giving up on everyone has always been the principle that China adheres to and what it is doing.

Some netizens estimate that China’s population of 1.4 billion will cost an upper limit of about 350 billion yuan for free vaccines. This is obviously not something that can be explained clearly by economic logic, and has risen to the level of political ethics.

Perhaps this is the superiority of socialism! Explain all the precautions for vaccination clearly at once. If you don’t understand, don’t get vaccinated easily.

This is an emergency vaccination, so people with high risk of exposure are given priority, and ordinary people can wait. In addition, COVID-19 is different from influenza. Different strains of influenza are used to produce influenza vaccines every year. Although the new coronavirus is currently mutating into several subtypes, it is still a new coronavirus. Annual vaccinations are not required.

1. Do I want a fight?

The first thing to consider when getting vaccinated is the risk of exposure if you don’t get vaccinated. At present, the domestic situation is basically stable (there are occasional sporadic infections in individual areas, most of which are imported from abroad), and the risk of exposure to ordinary people is limited. Wash your hands frequently, wear a mask, take daily protection, and don't gather in groups. You are safe and do not need vaccination. But those at high risk of exposure must fight!

2. Who doesn’t want to fight? ?

The following suggestions are from a scientific perspective, not based on personal wishes.

Not recommended for the following groups:

1. Do not take it if you are younger than 18 years old or older than 59 years old, pregnant or lactating, or planning to become pregnant.

2. Do not take this if you are allergic. (Those with allergies or a history of vaccine allergy cannot take the shot; if you are allergic to the first shot, do not take the second shot.)

3. Those who are currently feeling unwell, including fever, acute inflammation and infection, Do not take medications for acute attacks of chronic diseases, as well as particularly serious chronic diseases. (Ordinary patients with chronic diseases can still take the shot when they are not in an acute attack period)

4. People with immune deficiencies (HIV, congenital immune deficiency, lymphoma, leukemia undergoing chemotherapy, etc.) must not take the shot. Will you die?

5. Do not take the vaccine if you have severe respiratory disease, severe cardiovascular disease, severe liver or kidney disease.

6. Those with a history or family history of convulsions, epilepsy, encephalopathy or mental illness; those suffering from uncontrolled epilepsy and other progressive neurological diseases, and those with a history of Guillain-Barre syndrome should not take the vaccine.

7. It is not recommended for patients with complications of hypertension and diabetes that cannot be controlled by medication.

8. For any other matters that cannot be discussed, please ask the doctor. Explain your personal health status and historical health status, and let the doctor make a judgment.

The current vaccine focus is on healthy young and middle-aged people among those at high risk of exposure, while others should wait.

3. If you have been infected with COVID-19, do you still need to get vaccinated?

Those who have recovered from the infection will have antibodies, but the effective time of the antibodies is a problem, especially for those who are asymptomatically infected. Moreover, there are also cases of secondary infection, indicating that immunity is not absolute. I suggest you refer to question 1. Are you a high-risk group?

4. Can it be given together with other vaccines? ?

Theoretically, it is possible, but there is still a lack of data support, so it is not recommended to mix it with other vaccines. If the situation calls for a fight, pay attention to priorities.

For example, if you have already started taking HPV shots, wait a month after the HPV shots are completed before taking the COVID-19 shot; if you go abroad, take the COVID-19 shot first and then consider other things.

If it is rabies vaccine and tetanus that may be fatal if not administered, you must get vaccinated first, regardless of whether you have already been vaccinated against COVID-19!

5. Is it safe? What are the side effects? ?

There are currently no reports of serious adverse reactions among the millions of people who have received emergency vaccinations in China. Common adverse reactions are generally: pain, itching, numbness and swelling (conventional immune response), as well as individual symptoms such as fever, fatigue, nausea, headache, etc., and other symptoms cannot be ruled out at present.

So after vaccination, you need to stay at the vaccination site for 30 minutes for observation, and then observe whether these symptoms subside in the next 2-3 days.

If your symptoms are serious or you cannot tell whether your symptoms are serious, seek medical attention in time!

6. Will everything be fine after vaccination? ?

No! ! ! No COVID-19 vaccine can provide 100% protection. Even if you have been vaccinated, you should be protected, isolated, and throat-pierced, there is nothing special about it. In addition, poking your throat may result in a positive result. In this case, you need to provide vaccination records to prove that you are not infected. Let me tell you, for workers like us who are working in a company and have no time to party and play, just wait a little longer!

7. How long will the vaccine last?

One injection and two injections, 14-28 days apart. The antibody concentration reaches its highest 14-28 days after the second war, which is the theoretical peak protection. Those who need to go abroad can reverse the vaccination time. For example, if you are going abroad in early March, you should get vaccinated now. As for how long the protection lasts, it is conservatively estimated to be half a year, but now it is expected to last up to a year.

8. The virus has mutated, is the vaccine still effective?

That definitely won’t work! But don’t worry, only large-scale mutations will affect the vaccine, and scientific researchers are always keeping an eye on it! It has not yet been discovered. Even if it is discovered, the next vaccine can be developed and mixed for vaccination. For example, this is how HPV bivalent, quadrivalent, and nine-price came about. Maybe the new coronavirus vaccine will also have bivalent, quadrivalent, or something like that. So, don’t worry when Azhong is doing things!

9. How many vaccines are currently available? Are ours good? ?

The global COVID-19 vaccine research and development technologies mainly include (currently there is no data to verify which process vaccine is better): inactivated vaccine gene recombinant vaccine vector vaccine (including adenovirus vector, attenuated influenza virus vector) Nucleic acid vaccines (mRNA vaccines, DNA vaccines)

Scientific evaluation of the quality of a vaccine requires comprehensive consideration of its safety, effectiveness, and accessibility.

The current emergency vaccination in our country is inactivated vaccine. Judging from the disclosed data, it is safe and controllable.

10. If I want to be vaccinated, how do I make an appointment? ?

Key groups: You can make unified reservations for vaccination through your work unit.

People traveling abroad: Individuals who need to travel to medium- and high-risk countries or regions for work or study can make an appointment for vaccination through social health centers and other channels.

General population: Those who meet the conditions (i.e., except for the groups listed in question 2) voluntarily apply for vaccination according to their epidemic prevention needs. Please consult the local health department or the Centers for Disease Control and Prevention for details.

When the epidemic occurred, we responded quickly, controlled and prevented the epidemic, developed a vaccine, and vaccinated it free of charge. It only took one year. This is China speed! I sincerely hope that after 2020, when the word "domestic" is mentioned, there will be less doubt and more pride. ?
