Brief Summary

The COVID-19 pandemic is causing unprecedented morbidity and mortality.The safe and effective Novel coronavirus vaccine is an effective means to block the transmission of the virus by building up the immune barrier of the population.Clinical studies have shown that elderly people are at high risk of severe COVID-19 infection and have poor clinical prognosis.Considering the current situation of aging population in China, the elderly people should be given priority to vaccinate to obtain protection and reduce the risk of novel coronavirus infection.However, the current data on vaccines are mostly from young and middle-aged healthy people, while there is little research data on COVID-19 vaccination in the elderly.This study mainly studied the safety and effectiveness of COVID-19 vaccine in the elderly population and explored its potential immune mechanism.
