At present, the epidemic prevention and control in Shanghai is still in a critical period. Vaccination is the most effective means to block the spread of the epidemic. All districts in Shanghai focus on the "elderly" and provide a series of safe and convenient services to enable citizens to vaccinate at the door of their homes and buildings, so as to further accelerate the improvement of vaccination coverage for the elderly. In order to facilitate the vaccination of residents, Putuo District of Shanghai has transferred medical forces to carry out mobile vaccination services in "epidemic free communities" since late April. She Feng, director of Taopu town social development office, introduced that in order to serve the elderly group well, the community had a thorough understanding of the vaccination situation of the elderly in advance, and then fed back the vaccinated elderly, vaccinated manufacturers and other information to the town community health service center to accurately connect the information at both ends of supply and demand, so as to improve the vaccination efficiency. After the vaccination into the community, in order to avoid crowd gathering, the residents' committee staff and volunteers plan the route in advance, divide the work and cooperate, call the number by building and vaccinate by section. In recent days, in front of the small parking lot of Yiliu apartment on Changshou Road Street, a "vaccination line" has been working in an orderly manner. The vaccination site is divided into registration and evaluation area, vaccination area and outdoor observation area. In the registration link, the elderly residents can automatically generate the vaccination QR code by scanning their ID card. Residents need to provide vaccination code, health code, nucleic acid test report within 48 hours or antigen negative record within 24 hours. They can be vaccinated after signing the informed consent for vaccination. The on-site community staff said, "everyone responded very positively. The number of vaccinations was higher than expected, and nearly half of them were over 60 years old". In addition, taking into account the recent gradual rise in temperature, many temporary vaccination sites have also set up blue sunshade tents. "Although it is a temporary vaccination site, it is very considerate in all aspects, and it is very convenient to vaccinate in the community." A Shanghai citizen said that he had not been vaccinated with the "booster needle" because of his busy work. He added protection to himself by taking advantage of the vaccination to "enter the community". It is reported that according to the relevant epidemic prevention requirements, mobile vaccination sites will be added in eligible communities in Shanghai to expand the scope of vaccination, especially to improve the vaccination coverage of elderly groups.
