On the afternoon of March 28, the Joint Prevention and Control Mechanism of the State Council held a press conference to introduce the vaccination and supply guarantee of COVID-19 vaccine.

Essential points for COVID-19 vaccination

Q:1. What should I do if I am not sure whether I am suitable for vaccination?

A: If it is truly contraindicated, it should not be inoculated. If it is a prescribed condition, it is recommended to inform the doctor before vaccination.

Q:2. How long is the protection period of the vaccine?

A: Based on antibody levels, it's probably over 6 months. However, antibodies are not the only protective indicators, and related studies will be carried out in the future.

Q:3. We have received the COVID-19 vaccine, do we need to vaccinate again?

A: The booster injection was designed in the clinical process of the overall design. In the future, A phase III clinical study will be carried out overseas to determine whether the booster injection should be used.

Q:4. What is the preventive effect of COVID-19 vaccine?

A: The vaccine itself protects against infection, illness, severe illness and death.

Q:5. After the first dose, how long is the best time to give the second dose?

There is a level of antibody 9 months after inoculation

Zhang Yuntao, vice president of Sinopharmaceutical China Biology, said the preliminary results showed that the booster needle could effectively improve the durability of the antibody and the ability of the vaccine to resist mutation.

We also need to conduct a phase III clinical study overseas to continue to observe and see how long-lasting the protection is.

Whether a booster injection is needed or not will be answered according to the results of the next three phase clinical studies.

A new coronavirus booster needle has been designed to enhance antibody persistence

For the elderly over 60 years old

Mass vaccination was carried out

Some regions have begun to vaccinate people over 60 years of age who are in good physical condition under the condition of full assessment of their health status and if infected.

According to the inoculation of the first and second stage clinical elderly group in China and the feedback of large-scale overseas use, the incidence of adverse reactions of vaccine inoculation in the elderly group is relatively low.

To date, no abnormal cases associated with the vaccine have been detected.
