MERS-CoV seroconversion amongst Malaysian Hajj pilgrims returning from the Middle East, 2016-2018: results from the MERCURIAL multiyear prospective cohort study.

Prospective cohort study to investigate the potential exposure to the Middle East Respiratory Syndrome-Coronavirus (MERS-CoV) following Hajj pilgrims is still very limited. Here, we report the antibody seroconversion study results obtained from successive three years cohort studies (2016-2018) involving the Malaysian Hajj pilgrims returning from the Middle East. A cohort study of Hajj pilgrims from Malaysia enrolled 2,863 participants from 2016-2018, all of whom consented to provide paired blood samples for both pre- and post-Hajj travel to the Middle East. ELISAs and micro-neutralization assays were performed to detect the presence of MERS-CoV IgG antibodies. Sociodemographic data, symptoms experienced during Hajj, and history of exposure to camels or camel products were recorded using structured pre- and post-Hajj questionnaires. A 4-fold increase in anti-MERS-CoV IgG between paired pre-Hajj and post-Hajj serum samples in twelve participants was observed. None of the twelve ELISA-positive sera had detectable levels of virus-neutralizing antibodies. All reportedly had mild symptoms of respiratory symptoms at a certain point during the pilgrimage, implying mild or asymptomatic infections. No association between post-Hajj serum positivity and a history of exposure to camels or camel products was obtained. Findings from the study suggest that serologic conversion to MERS-CoV occurred in at least 0.6% of the Hajj pilgrims returning from the Middle East. Since all the seroconvertants had mild to no symptoms during the sampling period, it highlights the likelihood of occurrence of only low infectivity spillover infections among the Hajj pilgrims.

Malaysian Parents' Willingness to Vaccinate Their Children against COVID-19 Infection and Their Perception of mRNA COVID-19 Vaccines.

Little was known about Malaysian parental attitudes, beliefs, and intentions surrounding coronavirus disease 2019 (COVID-19) vaccines for children when the National COVID-19 Immunization Program for Children (PICKids) was launched in February 2021. A cross-sectional online survey-based study was carried out from 15 March 2022 to 23 July 2022 on Malaysian parents/guardians of children between ages 5 and below 12 years old. A total of 15.7% reported being extremely willing, and 38.9% were somewhat willing to vaccinate children with a COVID-19 vaccine. Perceived low susceptibility to COVID-19 infection showed the greatest significant impact on vaccine acceptance (OR 35.46, 95% CI 15.26-82.40). Parents with a lower level of concern have a higher willingness for vaccination (OR 1.25, 95% CI 0.90-1.75). Of the parents that knew of the mRNA vaccine, 46.6% reported that they prefer their children to be vaccinated with conventional vaccines over mRNA vaccines. Poor knowledge about mRNA vaccines, lack of confidence in the mRNA technology, fear of unknown side effects, and perception that the mRNA vaccines contain microchips were significantly associated with a higher level of concern about their children receiving an mRNA vaccine. Public education campaigns to promote COVID-19 vaccination for children warrant addressing the concerns and knowledge deficits among vaccine-hesitant parents.

Acceptability for COVID-19 vaccination: perspectives from Muslims.

This study aims to assess COVID-19 vaccine acceptance among Muslims in Malaysia. A cross-sectional internet-based survey was to determine acceptance of COVID-19 vaccine. Other influential factors, namely socio-demographics, COVID-19 experience, self-perceived level of religiosity, support in immunization, COVID-19 immunization attitudes, and health fatalistic beliefs (measured using the Helpless Inevitability Subscale of the Religious Health Fatalism Questionnaire, RHFQ-HI) were investigated. The majority reported a definite intent to receive the COVID-19 vaccine (57.3%; 95% CI 55.0-59.6) followed by a probable intent (42.7%; 95% CI 40.4-45.0%). COVID-19 immunization attitudes measured by attitudinal barriers to vaccination scores were found to be the strongest influence of COVID-19 vaccination intent, whereby participants who have lower attitudinal barrier scores reported higher COVID-19 vaccination intent (OR = 6.75 ; 95% 5.20-8.75). Although religious health fatalism was not significantly associated with vaccination intent, a significantly higher proportion of participants with score 4-9 (61.9%) in the RHFQ-HI reported intent to receive COVID-19 vaccine than those with a score of 10-20 (53.5%), p < .001. Intervention for people with skeptical attitudes toward COVID-19 vaccination is warranted.

Assessment of Impact of Containment During the COVID-19 Epidemic and Coping Behaviours Using Newly Developed Assessment Tools

Background: The confinement measures during COVID-19 had a massive effect on physical and psychological health in public. This study assessed the impact of containment and coping behaviour among the Malaysia public during the COVID-19 pandemic. Questions assessing the impact of containment and coping behaviours were developed and psychometrically tested. Methods: Exploratory factor analysis (EFA) was conducted with the items using principal component analysis extraction and Varimax rotation. Partial least squares structural equation modelling was used to determine the relationship between coping and impact. Results: The 13-item of impact and 10-item coping instruments were developed with three dimensions identified through EFA. Both scales demonstrated excellent composite reliability and good convergent validity. The survey findings revealed that the impact on individual psychological aspects was prominent, followed by well-being and lifestyle. Mindfulness and physical coping strategies were most commonly reported. Coping through seeking help from health professionals and hotlines had a positive direct effect on well-being and lifestyle (b = 0.231, p < 0.001), psychological (B = 0.132, p < 0.001), and employment-related (0.194, p < 0.001) impacts. Coping through mindfulness practise had a negative effect on well-being and lifestyle-related impact (B = −0.180, p < 0.001) and employment-related impact (B = −0.096, p = 0.008). Conclusions: Despite some limitation, the scales for measuring impact and coping behaviours have the potential to be used as a measurement tool in future studies. Findings highlight the enormous impact of the pandemic on psychological well-being and lifestyles. Health authorities should support individual coping as it was found to be an important resilience-related factor to mitigate the impacts of containment during the pandemic.

The use of the health belief model to assess predictors of intent to receive the COVID-19 vaccine and willingness to pay.

BACKGROUND: The development of a vaccine against SARS-CoV-2 infection is on the way. To prepare for public availability, the acceptability of a hypothetical COVID-19 vaccine and willingness to pay (WTP) were assessed to provide insights into future demand forecasts and pricing considerations. METHODS: A cross-sectional survey was conducted from 3 to 12 April 2020. The health belief model (HBM) was used to assess predictors of the intent to receive the vaccine and the WTP. RESULTS: A total of 1,159 complete responses was received. The majority reported a definite intent to receive the vaccine (48.2%), followed by a probable intent (29.8%) and a possible intent (16.3%). Both items under the perceived benefits construct in the HBM, namely believe the vaccination decreases the chance of infection (OR = 2.51, 95% CI 1.19-5.26) and the vaccination makes them feel less worry (OR = 2.19, 95% CI 1.03-4.65), were found to have the highest significant odds of a definite intention to take the vaccine. The mean ± standard deviation (SD) for the amount that participants were willing to pay for a dose of COVID-19 vaccine was MYR$134.0 (SD±79.2) [US$30.66 ± 18.12]. Most of the participants were willing to pay an amount of MYR$100 [US$23] (28.9%) and MYR$50 [US$11.5] (27.2%) for the vaccine. The higher marginal WTP for the vaccine was influenced by no affordability barriers as well as by socio-economic factors, such as higher education levels, professional and managerial occupations and higher incomes. CONCLUSIONS: The findings demonstrate the utility of HBM constructs in understanding COVID-19 vaccination intention and WTP.
