The coronavirus disease 2019 (COVID-19) outbreak caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) has affected various medical fields worldwide. However, relatively few studies have examined the impact of COVID-19 infection and vaccination on in vitro fertilization (IVF) outcomes changes antibody concentration follicular fluid (FF). A total 45 women were prospectively recruited assigned to 3 groups: uninfected non-vaccinated control group (Control group), infected (COVID + vaccinated (Vaccination group). Serum (FF) estradiol, progesterone, concentrations measured. There no statistical differences number retrieved oocytes (P = .291), mature .416), good-quality embryos .694) among groups. In group, BNT162b2 exhibited a significantly lower trigger-day serum estradiol/MII oocyte level (110.6 pg/mL) than other vaccines (289.5 .006).

Materials methods Human Development Index (HDI), Education (EI), Democracy (DI), COVID-19 rates, data were collected from sources such as UNDP - Reports, UNESCO Index, Economist Intelligence, WHO– Dashboard, Our World In Data, The Financial Times Dashboard. Statistical analysis Pearson correlation, linear regression analyses done to determine a relation between above-mentioned indices rates (1-dose, 2-dose, booster, combined).

The COVID-19 pandemic highlighted the critical importance of vaccination in controlling infectious diseases. While previous research has identified social cohesion as a potential facilitator health behaviors, empirical studies exploring its direct impact on rates, especially across different age groups, remain limited. This cross-sectional study utilized data from 2021 Korean Community Health Survey, nationally representative survey conducted South Korea. analysis focused adults aged 50 and older, categorizing them into two groups (50–64 ≥65). We investigated association between perceived neighborhood status, for socio-economic concerns related to COVID-19. Statistical was using complex sample multiple logistic regression adjust confounders. included 135,352 participants, with an showing that group ≥65, higher levels were significantly associated increased uptake (aOR trust neighbors: 1.200, 95% CI: 1.058–1.362; aOR mutual assistance among 1.491, 1.312–1.695). Interestingly, these associations not significant 50–64 group.
