NCT05012839
Background The impact of the coronavirus disease 2019 (COVID-19) pandemic on medical services is overwhelming due to limited medical resources. During its initial surge in 2020, Taiwan's government rapidly established diverse public actions, which helped maintain the medical supply without travel restrictions. However, whether the fear of being infected with COVID-19 interfered with health-seeking behavior (HSB) remains unclear. Therefore, this study aimed to elucidate whether acute complicated appendicitis (ACA) rates in adults were affected by the COVID-19 pandemic. Methods A retrospective analysis of acute appendicitis in adults was performed between January 1 and June 30, 2020 (COVID-19 period). The control period was collected from the first two quarters for the preceding 3 years. Outcome measures were ACA and length of hospital stays.

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.
