After scanning his mobile phone into the "Healthy Cloud" vaccination registration system, Dr. Zhang Wenhong carefully filled in his personal information. This step also needs to fill in the QR code representing the inoculation point of Huashan Hospital, which is also one of the traceable information. Finally, the first step of information registration is completed by signing the electronic informed consent form.
The second step in the registration process is to fill in the paper informed consent form manually. At the same time, the vaccination nurse confirmed several key information. The third step in the registration process is to input the barcode information generated in the first step into the inoculation point information platform. The nurse checked the name of the vaccinator again.
At present, according to the "two-step" vaccination plan for COVID-19 vaccine issued by National Health Commission, Shanghai has started emergency vaccination for key posts with high risk of COVID-19 infection (related personnel at imported cold chain cargo ports, overseas working and studying personnel, border port staff, medical and health personnel, etc.). In the future, Shanghai will also start to vaccinate people who go abroad for personal reasons with COVID-19 vaccine in due course. Domestic inactivated whole virus vaccine was used for inoculation, and the inoculation dose was 2 times, with an interval of 2 weeks to 4 weeks.
Extended data
Two weeks after the second dose of vaccine, it will have a good immune effect.
Wang Huaqing, chief expert of immunization program of China CDC, said that the inactivated vaccine should be given twice, and the immunization effect will be better. According to the vaccine literature published in COVID-19 in the early days, the vaccine mainly works two weeks after the second dose of vaccine, which will produce good immune effect.
According to previous research results, to block COVID-19, the immune threshold of the general population is around 70%, or slightly lower. How to choose the threshold is closely related to the vaccine protection efficacy and vaccination rate, which is in direct proportion. When the vaccination rate in the population reaches a very high level, the immune barrier is established. I hope to plant all kinds of vaccines when I have the opportunity.
