About the second dose of the novel coronavirus vaccine

With the gradual progress of national vaccination, in many areas of China, many people have received the first dose of the new coronavirus vaccine (mostly the new coronavirus inactivated vaccine implemented by the state), and are waiting for the second dose of the vaccine

.

However, because there is a certain time interval between the first and second dose, some problems also arise

.

But don’t be afraid

.

Xiaobian has sorted out three common problems in the second dose of the new coronavirus inactivated vaccine

.

Let’s have a look

.

Why does the vaccination interval change? It is believed that in many people’s cognition, the interval between the first dose and the second dose is 14-28 days

.

However, in the first edition of novel coronavirus vaccination guidelines (hereinafter referred to as the latest guidelines) issued by the Commission of health on March 29, the requirement for the interval between the first and second doses of vaccines has changed to 3-8 weeks

.

This is because the clinical trial of Kexing vaccine found that the protection efficiency of 2-shot interval < 21 days is lower than that of 2-shot interval ≥ 21 days

.

This may be related to the fact that the vaccine needs sufficient time for the human body to produce an immune response

.

Before vaccination is not standardized how to do? In many areas, new vaccines are still in short supply

.

Due to the difference of local vaccination, many vaccinations do not fully comply with the vaccination standards

.

In many areas, the vaccination interval is less than 14 days, or even two injections are inoculated together

.

In the face of this situation, the latest guidelines point out that if the vaccination interval is less than 14 days or even two injections are inoculated at the same time, the third dose should be replanted; If the interval of inoculation is more than or equal to 14 days, there is no need to replant

.

If the second dose is missed for some reason, leading to the delay of the second dose, there is no need to re vaccinate, just need to make up the second dose that has not been vaccinated

.

Can two injections of vaccine be mixed? Similarly, due to regional differences, people in many regions may not be able to get the second dose of vaccine from the same manufacturer after receiving the first dose from a certain manufacturer

.

In view of this situation, the latest guidelines point out that the same type of second dose vaccine from different manufacturers can be vaccinated

.

For example, if you choose to vaccinate with the new inactivated coronavirus vaccine, there will be no problem with the first dose of Beijing biological and the second dose of Beijing Kexing Zhongwei, and vice versa

.

I hope you can successfully complete the vaccination of the novel coronavirus vaccine and contribute your own strength to the anti epidemic work of the motherland
