Objective To observe the effect of extracts from Flos Lonicerae inhibiting influenza A virus FM1 strain. Method Use the method of hemagglutination test, determine the hemagglutination inhibition titer that extracts from Flos Lonicerae inhibiting influenza A virus in vitro and in embryonated egg. Result Compared with the control group, the hemagglutination inhibition titer of extracts from Flos Lonicerae group were degraded. The depressant effect kept on from 1 hour to 24 hour, and the depressant effect were degraded with the stepping down of the concentration. At the concentration of 100, 50, 25 mg/mL, extracts from Flos Lonicerae had the preventative effect and therapeutical effect on embryonated egg infected by influenza A virus (P

【Objective】 To understand the status of COVID-19 vaccination among elderly adults in long-term care facilities and analyze the influencing factors so as to provide scientific basis for improving the policy of COVID-19 vaccination. 【Methods】 The socio-demographic characteristics, disease-related data, disability, and COVID-19 vaccination status of 575 elderly adults who resided in long-term care facilities in Shaanxi Province were collected via Sojumpin in January 2022. Factors that affected non-vaccinated elderly adults were analyzed by using the SPSS 25.0 software. 【Results】 Of the included 575 participants, 199 (34.6%) were not vaccinated against COVID-19. Univariate analysis showed that COVID-19 vaccination was associated with age, room type, length of stay, marital status, number of children, chronic diseases (i.e., diabetes, stroke, dementia), disability degree, and long-term medication use. Logistic regression analysis demonstrated that age of 90 years or above (OR=4.25), triple room (OR=6.17), moderate disability (OR=2.94), severe disability (OR=6.67), long-term medication use (OR=1.81), and stroke (OR=1.74) were independent risk factors for not injecting COVID-19 vaccine. 【Conclusion】 The COVID-19 vaccination coverage rate of elderly adults in long-term care facilities needs to be improved, and more attention should be paid to the high-risk groups (e.g., who are older, and have disability, long-term medication use, or stroke).
