How about the development progress of other COVID-19 vaccines in China? Can the infected COVID-19 vaccine be used

Although the COVID-19 epidemic has been well controlled in China, the epidemic situation is relatively severe in some foreign countries, so the development of vaccine has become the most concerned topic. How about the development of other COVID-19 vaccines in China? What is the specific significance of the current new vaccine? The National Health Commission has responded!

I. What is the development progress of other COVID-19 vaccines in China?

As you know, at present, there are 17 COVID-19 vaccines entering the clinical stage in our country, 4 of which have been conditionally approved, and the other three technical routes are basically in the phase III clinical stage or will enter the phase III clinical stage immediately. Everyone is very concerned about the progress going forward. For these vaccines, there must be two tasks before they are launched: one is to ensure that the safety and efficacy data of Phase III clinical trials comply with regulations, and the other is to complete commercial scale production process validation and establish reliable quality standards for control. Clinical trials require sufficient clinical research data, and there are significant difficulties in phase III clinical trials, which are all conducted abroad and require overcoming many challenges. What is the specific significance of the current new vaccines? Once sufficient data is obtained to demonstrate the effectiveness and acceptable safety of the proposed plan, the applicant can submit a marketing application to the National Medical Products Administration (NMPA). The NMPA will organize the review process as soon as possible to ensure the safety and effectiveness of the vaccine.

III. Can people infected with Wuhan COVID-19 vaccine fight? Generally speaking, those who have been infected with infectious diseases or asymptomatic infections will develop corresponding immunity and should have a protective effect similar to vaccination. Moreover, at present, the clinical trials have not provided the safety and effectiveness data of the cured population of COVID-19.

Therefore, people cured by COVID-19 are not recommended to be vaccinated with COVID-19 vaccine.
