    Abstract The impact of vaccine hesitancy on global health is one that carries dire consequences. This was evident during the outbreak of the COVID-19 pandemic, where numerous theories and rumours emerged. To facilitate targeted actions aimed at increasing vaccine acceptance, it is essential to identify and understand the barriers that hinder vaccine uptake, particularly regarding the COVID-19 vaccine in Ghana, one year after its introduction in the country. We conducted a cross-sectional study utilizing self-administered questionnaires to determine factors, including barriers, that predict COVID-19 vaccine uptake among clients visiting a tertiary and quaternary hospital using some machine learning algorithms. Among the findings, machine learning models were developed and compared, with the best model employed to predict and guide interventions tailored to specific populations and contexts. A random forest model was utilized for prediction, revealing that the type of facility respondents visited and the presence of underlying medical conditions were significant factors in determining an individual's likelihood of receiving the COVID-19 vaccine. The results showed that machine learning algorithms can be of great use in determining COVID-19 vaccine uptake.

    Abstract The BCG vaccine, like all other vaccines, is associated with adverse events following immunization (AEFI). Reducing the incidence of AEFI is crucial in reposing confidence in BCG vaccination and reducing hesitancy associated with the vaccine. This requires safety precautions before and during vaccinations, as well as reporting AEFIs after vaccination. This study assessed the adherence of health-care professionals to pre-vaccination precautions and adverse events following immunization (AEFI) reporting practices during BCG vaccination in four hospitals in Ghana. It is hoped that the findings of the study will serve as a baseline to identify gaps for further studies to generate a stronger evidence for policy formulation aimed at improving BCG vaccine safety in Ghana and other tuberculosis endemic countries. A cross-sectional study design was employed, and Statistical Package for Social Sciences, IBM® SPSS version 25 (SPSS Inc. USA) software was used for analysis. Chi-square and binary logistic regression tests were used to test the association between categorical variables and predictors of adherence to pre-BCG vaccination precautions, respectively, and a p-value of <.05 was considered statistically significant. The AEFIs commonly reported by mothers included abscess, injection site pain, injection site redness, fever, rash, muscle weakness, diarrhea, vomiting, coughing and rhinitis. Ninety-three participants (73.2%) were adherent to pre-BCG vaccination precautions. Ninety-two participants (72.4%) informed mothers to report all AEFIs encountered. Adherence to pre-BCG vaccination precautions and AEFI reporting were generally good; however, there is still room for improvement.

    Abstract Hypertensive disorders associated with pregnancy are a major health concern and a leading cause of maternal indisposition and transience. The main objective of this study was to assess the prevalence of hypertension in pregnancy as well as antihypertensive therapy and pregnancy outcomes among pregnant women at Tamale Teaching Hospital (TTH) in Ghana. This was a retrospective study conducted using data from the folders of pregnant hypertensive patients. The study was conducted at the maternity ward of TTH from 1 June 2018 to 31 May 2019. Participants were all pregnant women with a diagnosis of hypertensive disorders. The prevalence of hypertensive disorders in pregnancy was 12.5%. The most common antihypertensive medication prescribed was sustained-release oral nifedipine, which was prescribed for 548 (81.4%) participants either alone or with methyldopa, followed by oral methyldopa: 506 (75.2%), intravenous hydralazine: 94 (14.0%), intravenous labetalol: 28 (4.2%) and diuretics: 10 (1.5%). Thirty-eight (5.7%) babies died before delivery, whereas 635 (94.3%) babies were born alive. Twenty-six out of the 38 dead babies (68.4%) were babies of pregnant women with elevated BP, whereas 12 (31.6%) were babies of those with normal BP. There was a statistically significant association between BP control and delivery outcomes. The study observed adherence to antihypertensive medicines recommended by the standard treatment guidelines of Ghana for the management of hypertensive disorders in pregnancy. The BPs of about two-thirds of the study participants were well controlled with the antihypertensive therapy. The majority of the study participants with well-controlled BP had positive delivery outcomes.

    Abstract Background: Despite the significant role played by vaccines in global health, concerns over vaccine safety have increased tremendously over the years. There have been occasions where vaccines have caused rare, adverse reactions some of which have led to hospitalizations and even death. It is therefore important to establish the safety profile of routinely used vaccines in order to allay fears pertaining to their use.
    Objectives: This review was aimed at pooling together the safety data of selected vaccines used for routine immunization in Africa, a region of the world with paucity of vaccine safety data.
    Methods: Adverse Events Following Immunization safety data was searched for rotavirus, yellow fever, measles, rubella, tuberculosis (Bacillus Calmette Guerin-BCG), pneumococcal, Haemophilus Influenza type b, polio, meningococcal and the influenza A (H1N1) vaccines in PUBMED, Google Scholar, Clinical trials.gov and Cochrane controlled register of trials databases.
    Results: A total of twenty-four serious AEFIs and twenty-three minor AEFIs were identified from the review. The strength of association between AEFIs and vaccine was high for tuberculosis vaccine and moderate for all other vaccines.
    Conclusion: Even though AEFIs (including mild and severe) were identified in the review, all the vaccines studied were generally well tolerated.

    Abstract Globally, countries are still battling health challenges and the negative economic stress on the citizenry caused by COVID-19. This study explored the perspectives of market women in Ghana and South Africa on COVID-19. Data collection was executed in both Ghana and South Africa between March 2021 and December 2021. Employing semi-structured questionnaires, face-to-face interviews were conducted. Most of the market women in Ghana described COVID-19 as a global pandemic, while market women in South Africa described the disease as the deadly flu. There were similarities in the perceived signs and symptoms of COVID-19. Market women in both countries specifically observed that not adhering to the safety protocols was the major mode of transmission. Lemon, garlic and ginger were the most common foodstuffs used by the market women to fight COVID-19. To prevent COVID-19 at their places of work, market women stressed the importance of observing the safety protocols. An overwhelming majority of market women in both countries bemoaned the negative impact of COVID-19 on their businesses and suggested the need for financial assistance from their respective governments. The findings are intended to assist policymakers in both Ghana and South Africa to implement interventional projects to assist women whom the literature suggests are the most vulnerable during pandemics such as COVID-19.

    Abstract This study assessed adverse events following immunizations (AEFIs) reported on COVID-19 vaccines in VigiAccess and determined the reporting trends across all continents of the world. The study was cross-sectional quantitative in design. VigiAccess was searched on 10 November 10 2021 for reported adverse events following the introduction of COVID-19 vaccines. After entering the search term, "COVID-19 vaccines" in VigiAccess, AEFIs associated with nine approved brands of COVID-19 vaccines had been documented in the database. Data were captured among age groups, sex, and continents of the world and analyzed using Statistical Package for Social Sciences (SPSS) version 25. Overall, 2,457,386 AEFIs had been reported in VigiAccess at the time of the search. No causal associations could be established between the vaccines and the AEFIs. The public accessing VigiAccess data should therefore be made aware of this in order to not falsely attribute AEFIs to COVID-19 vaccines when assessing the database.

    Abstract Background: Many of the cancer cases in Zimbabwe are HIV related, making it a significant health concern in the country. This concern requires innovative ways, such as implementing Value-Added Tax (VAT) to finance cancer management through health insurance. The study explores the general public, cancer patients, and public authorities' perception regarding using the VAT system for financing cancer treatment.
    Method: A qualitative cross-sectional study was conducted to explore the perception of study participants on 'Value Added Tax' as a source of healthcare financing in Harare. This was done through the use of in-depth interview guides. A total of 25 participants took part in the study. Fifteen were members of the general public, 5 were cancer patients, and 5 were key informants representing public authority. Members of the general public and cancer patients were conveniently selected, while key informants were purposively selected. Data were analyzed descriptively and by grounded theory whereby codes were developed by induction.
    Results: The general public and cancer patients perceived cancer treatment as generally unaffordable and showed readiness to pay for a cancer levy through VAT. Cancer patients expressed disappointment at the low support for cancer treatment compared to HIV treatment concerning the already established AIDS levy. Public authorities also perceived the VAT system as an appropriate programme for health care financing.
    Conclusion: This preliminary study found that a 'Value-Added-Tax' system could potentially be an acceptable model to finance public healthcare, including cancer treatment in highly informal settings like Zimbabwe.

    Abstract Background: Cancer is one of the leading causes of death globally. Owing to high toxicity, patients using chemotherapy drugs have a higher risk for developing adverse drug reactions (ADRs). Pharmacovigilance studies are essential in oncology to evaluate ADRs caused by anticancer drugs and improve patient safety. This study aimed to analyze serious ADRs associated with the use of doxorubicin and epirubicin reported to VigiBase.
    Method: All anonymized data on suspected ADRs for doxorubicin and epirubicin as 'serious' and 'suspected' or 'interacting' drugs between 1968 and 30 August 2021, were extracted from VigiBase. Descriptive statistics were conducted in Microsoft Excel, and data were summarized using frequencies and percentages.
    Results: A total of 35,620 serious individual case safety reports was analyzed. The majority of reports were from females (Dox = 61.41%; Epi = 86.56%), while the predominant age group was 45-64 years (Dox = 42.06%; Epi = 57.39%). Physicians were the more likely group to report serious ADRs (Dox = 50.03%; Epi = 34.11%). In general, Europe reported the highest for doxorubicin (38.08%), while Asia recorded the highest reports for epirubicin (53.28%). Oceania reported the least for both drugs (Dox = 0.45%; Epi = 0.04%), followed by Africa (Dox = 0.72%; Epi = 0.29%). Blood and lymphatic system disorders were the most reported serious category (Dox = 11053 [44.47%]; Epi = 6659 [61.84%]). The most common manifestations were febrile neutropenia (Dox = 10.52%) and bone marrow failure (Epi = 23.89%).
    Conclusion: This study provides relevant global insights into serious ADRs for doxorubicin and epirubicin. This knowledge may assist in minimizing and proactively managing ADRs. It can also inform policies to improve patients' quality of life.

    Abstract Introduction: The World Health Organization has reported a rise in cervical cancer in Ghana. Ghanaian women predominantly undergo opportunistic Pap smear screening for cervical cancer. Numerous studies have documented differences in the sociodemographic traits of participants undergoing Pap smear testing or screening, which correlates with their screening habits. This study aims to assess sociodemographic variables, including others that determine Pap test utilization at a single center in Ghana.
    Methods: A single-center survey was conducted by extracting data from the records of women who walked in for Pap smear testing. A telephone survey was also conducted among these women to document their barriers to utilizing the center. For data analysis, descriptive statistics and chi-square were utilized.
    Results: A total of 197 participants' records were retrieved for the study. Most participants were market women (69.4%) and uneducated (71.4%). Their Pap smear screening records indicate that the majority (86%) had no history of cervical cancer screening, and only 3% tested positive for Pap smear test. Educational level, occupation and family history of cancer significantly correlated with participants' Pap smear history (p<0.05). However, most sociodemographic factors were not significant with the Pap test results of the participants (p>0.05). The perceived barrier identified by most participants was the need for more information (67.40%) on the test.
    Conclusion: This study revealed that sociodemographic and gynaecological factors do not correlate with Pap test results. However, education level, occupation, and family history of cancer were significantly associated with the history of Pap smear uptake. The most significant barrier hindering Pap smear services was the need for more information.
