Objective The coronavirus disease 2019 (COVID-19) pandemic has had a serious impact on health all over the world. Cancer patient, whose immunity is often compromised, faces a huge challenge. Currently, some COVID-19 vaccines are being developed and applied on general population; however, whether cancer patients should take COVID-19 vaccine remains unknown. Our study aimed to explore the knowledge, attitude, acceptance, and predictors of intention to receive the COVID-19 vaccine among cancer patients in Eastern China. Methods A cross-sectional study was conducted in Eastern China from June 17th to September 3rd, 2021. Patients were selected using a convenience sampling method. A self-report questionnaire was developed to assess knowledge about the COVID-19 vaccine, attitude towards the vaccine and acceptance of the vaccine; following a review of similar studies previously published in the scientific literature, multivariate logistic regression analysis was used to determine the predictors associated with COVID-19 vaccine acceptance. Results A total of 2158 cancer patients were enrolled in this study. The rate of vaccine hesitancy was 24.05% (519/2158); further, among the participants of vaccine acceptance, 767 had taken COVID-19 vaccine (35.54%), and 872 were willing to get vaccinated (40.01%). A total of 24 variables including demographic characteristics, clinical status of cancer, impact of COVID-19 pandemic on study participants, patients’ knowledge about the COVID-19 vaccine, and attitude towards the vaccine, had significant differences between the “vaccine hesitancy” population and “vaccine acceptance” population. Multivariate logistic regression analysis indicated that parameters including alcohol consumption (odds ratio [OR] = 1.849; 95% confidence interval [CI]: 1.375–2.488; P -reference [ P -Ref] < 0.001 vs non-drinkers), income impacted by COVID-19 pandemic (OR = 1.930, 2.037 and 2.688 for mild, moderate, and severe impact, respectively; all P -Ref < 0.01 vs no impact), knowledge of how the vaccine was developed (OR = 1.616; 95% CI: 1.126–2.318; P -Ref = 0.009 vs unknown), believing in the safety of the vaccine (OR = 1.502; 95% CI: 1.024–2.203; P -Ref = 0.038 vs denying the safety of vaccine), willingness to pay for the vaccine (OR = 3.042; 95% CI: 2.376–3.894; P -Ref < 0.001 vs unwilling), and willingness to recommend families and friends to get vaccinated (OR = 2.744; 95% CI: 1.759–4.280; P -Ref < 0.001 vs do not recommend) were contributors to vaccine acceptance. While such as being retired (OR = 0.586; 95% CI: 0.438–0.784; P -Ref < 0.001 vs...

The global monkeypox outbreak in 2022 has severely affected the life and health of people. Currently, partial smallpox vaccines have been approved for monkeypox prevention. Considering the potential occupational health risks of monkeypox infection among healthcare workers (HCWs), this study explored the willingness of Chinese HCWs to receive the monkeypox vaccine and analyzed the factors influencing their decision. We conducted an online cross‐sectional survey among HCWs of 10 Chinese hospitals from May 30th, 2022 to August 1st, 2022. Specifically, a self‐report questionnaire was administered to evaluate the attitude and acceptance of HCWs toward the monkeypox vaccine, followed by a multivariate logistic regression analysis to determine the independent predictors of vaccination. The survey included 1032 participants, of whom 90.12% expressed their willingness for vaccination (vaccine hesitancy rate = 9.88%). Univariate analysis showed that 11 variables differed significantly between the vaccine acceptance and vaccine hesitancy groups. Multivariate logistic regression analysis demonstrated that the age of 30–40 years (odds ratio [OR] = 0.504, 95% confidence interval [CI]: 0.284–0.893, p = 0.019 vs. age of <30 years old), working in a secondary hospital (OR = 0.449, 95% CI: 0.249–0.808, p = 0.019 vs. working in a tertiary hospital), considering vaccination necessary for controlling monkeypox infection (OR = 4.135, 95% CI: 2.109–8.106, p < 0.001 vs. not considering it necessary), willingness to pay for the monkeypox vaccine (OR = 2.125, 95% CI: 1.206–3.745, p = 0.009 vs. no willingness to pay), considering implementation of mandatory vaccination necessary (OR = 1.990, 95% CI: 1.023–3.869, p = 0.043 vs. not considering it necessary), and recommending family members and friends to take the vaccine (OR = 13.847, 95% CI: 7.487–25.609, p < 0.001 vs. not recommending) were crucial independent predictors of the willingness to receive monkeypox‐related vaccination. This study evaluated the acceptance and hesitancy rates of Chinese HCWs toward the monkeypox vaccine and found that the willingness to receive vaccination was mainly correlated to age, hospital level, and attitude toward vaccination. Therefore, to promote vaccine absorption, we recommend expanding publicity, formulating reasonable policies, and improving the recognition of vaccines.

BackgroundThis study aimed to investigate the association of serum concentrations of vitamin A, D, and E with recurrent respiratory tract infections (RRTIs).MethodsA total of 1200 children aged at 0.5–14 years were selected via a face-to-face survey in Harbin, China. Among the participants, 600 children with RRTIs comprised the symptomatic group (RRTI group), whereas 600 healthy children were used as controls (control group). Blood samples were collected to measure serum levels of vitamins A and E by HPLC; the serum level of 25-hydroxycholecalciferol (25(OH)D), was measured by HPLC-MS/MS.ResultsSerum levels of vitamins A and E, as well as 25(OH)D, were significantly lower in the RRTI group than the control group. The conditional logistic regression model and the receiver-operating characteristic curve showed that the insufficiency or deficiency of vitamins A, D, and E was positively correlated with RRTI occurrence (p < 0.05).ConclusionsLow serum concentrations of vitamins A, D, and E were associated with RRTIs in children from northern China.
