COVID-19 vaccine booster, did you get it?

COVID-19, here comes the booster. Did you get it? There is still one month before the end of the 11 th holiday. This month can be said to be full of crises! COVID-19 patients have been found in many provinces of China. Do you feel horrible? However, with the efforts of epidemic prevention personnel, this epidemic will eventually pass.

At present, more than 20 provinces have started the intensive vaccination of COVID-19 vaccine. Should we get this booster vaccine? What should I pay attention to? I'll talk to you about two or three things about vaccination today ~

Why do you need to strengthen the injection?

Will there be a fourth needle and a fifth needle in the future?

We know that after vaccination, we will produce protective antibodies in our bodies. If we are exposed to COVID-19 virus, antibodies will neutralize the virus, thus preventing infection, especially severe cases, and reducing mortality.

But if the time is too long, the antibody level in the body will weaken with time. In order to ensure the stability of our immunity, we need to vaccinate booster vaccines according to the immune characteristics of different vaccines. So as to stimulate the body to improve the antibody level in vivo, maintain it for a longer time and improve the protective effect.

"Nature" magazine reported that Yale University in the United States found that the risk of reinfection increased by 50% after 17 months if patients recovered from the infection of coronary heart disease without wearing masks and vaccinating, which was also proved by the research of the Centers for Disease Control and Prevention in August this year.

Many people have this misunderstanding. Will I not be infected with COVID-19 virus after vaccination? This idea is wrong. Even if you are vaccinated, you may be infected with COVID-19 virus.

Vaccine plays a role in preventing the development of severe diseases, but it can't 100% prevent infection, so even if it is vaccinated, it is even vaccinated with booster needles. Winter is coming. Most experts predict that the epidemic situation in COVID-19 will get worse in winter. In this case, protective measures such as wearing a mask, washing hands frequently and keeping social distance should be taken.

As for whether there will be a "fourth needle" or a "fifth needle" in the future, it is still uncertain. We need to adjust the way to enhance immunity according to the variation of virus and the change of antibody level in our body.

Can booster needles prevent mutant strains? I believe that everyone has understood COVID-19's ability to mutate. Since the outbreak, there have been more than 1000 mutants in COVID-19! In particular, the Delta mutant, which made a lot of noise a few days ago, has more than twice the spreading power of the non-mutant virus, even surpassing SARS, smallpox and influenza, so some people suspect that it is useless to get a booster shot. ...

This idea is wrong!

From May to June in 20021year, an outbreak of δ COVID-19 occurred in Guangdong Province, China. The Guangdong Provincial Center for Disease Control and Prevention has observed the infected people who have completed two doses of vaccine. It was found that the protective effect of inactivated vaccine in China reached 70% in COVID-19 Delta, and the protective rate of severe infection in COVID-19 was 100%. Those who are not vaccinated have little immunity to COVID-19.

After vaccination, the antibody level in the body has been greatly improved and the immunity has been strengthened. The antibody produced has a longer existence time and can produce good cross-neutralization protection for mutants such as Delta.

Who can inject the enhancer?

At this stage, priority should be given to strengthening the immunization work of high-risk groups and key post groups, ensuring the basic operation of society, people who meet the requirements of epidemic prevention and control of major events and the elderly aged 60 and above, and people who need to be vaccinated after completing the second dose of vaccine for 6 months. Friends who meet the vaccination conditions should adhere to the principle of all finished shots and get COVID-19 vaccine booster shots in time.

Strengthening the vaccination of vaccines needs to be differentiated according to the types of vaccines, such as 2 shots of Newcastle disease inactivated vaccine or virus vector vaccine 1 shot. And intensive injection can only be vaccinated after 6 months.

This is because strengthening the needle is to consolidate and improve the vaccine effect. In principle, what vaccines have been vaccinated before, and what vaccines have been injected. At present, the strategy of strengthening immunization in China is vaccination with the same technical route, and mixed vaccination is generally not recommended (you can check your vaccination record and the last vaccination time through Health Treasure, and then postpone vaccination for 6 months).

If other vaccines are vaccinated during this period, it is best to be separated from other vaccines for at least two weeks to minimize unexpected interactions. At the same time, we should also closely observe the reaction after vaccination, and it is best to consult the doctor in charge of vaccination.

In addition to the above, when rabies vaccine, tetanus vaccine and immunoglobulin need to be vaccinated due to animal injury, trauma and other reasons, the vaccination interval with COVID-19 vaccine may not be considered.

What preparations do you need for vaccination? Please bring your ID card, mobile phone and other valid documents and tools before vaccination.

After vaccination, you need to stay in place for at least 30 minutes. You should rest more and drink more water when you get home.

Do not drink alcohol 3 days before and 3 days after vaccination. Do not take a bath on the day of inoculation, keep the injection site clean and sanitary, and do not squeeze and massage the inoculation site to prevent local infection. After inoculation, the diet should be light, and if you are allergic, eat less spicy and seafood foods.

As for where to get the vaccine? You can go to the vaccination unit in COVID-19 approved by the local health administrative department for vaccination.
