The COVID-19 vaccination campaign is an ongoing worldwide effort to vaccinate large numbers of people against COVID-19 in order to ensure protection from the disease, control the rate of infection, reduce severe outcomes, and get back to normal life. Most African countries had a delay in the initiation of their COVID-19 vaccine national rollout compared to other regions in the world, and the goal of the immunization exercise in the continent is to vaccinate over 60% of the African population to attain herd immunity. Over the years, vaccination programmes are usually faced with challenges in Africa because of numerous factors. So far, some of the major challenges threatening the success of the COVID-19 vaccination rollout in most African countries includes the slow onset of the vaccination exercise, limited funds, concerns around vaccine safety and uncertainties, storage requirements and regulatory hurdles for vaccines, limited shelf life of COVID-19 vaccines, inability to access vulnerable communities in a timely fashion, problems around the use of different vaccines, and wars and conflicts. The solutions and other imperative recommendations to these challenges were provided so as to optimize the vaccination programme and to achieve an appreciable success in the COVID-19 vaccination programme on the continent. In conclusion, a holistic and timely planning, fast execution of plans, rigorous community involvement, and a robust multi-sectoral partnership will ensure a successful COVID-19 vaccination campaign in Africa.

The aim of this review is to give a synopsis on the coronavirus disease 2019 (COVID-19) pandemic, with major focus on the preventive measures. Ever since the influenza pandemic of 1918, and the second world war of (1939)(1940)(1941)(1942)(1943)(1944)(1945), the world has not been faced with a common problem in recent memory like the COVID-19 pandemic. The unprecedented COVID-19 pandemic is caused by infection with a viral pathogen, the nascent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and is characterized by respiratory failure in severe cases. The communicability period of COVID-19 varies, but it is usually between 2-14 days, and the major signs and symptoms of COVID-19 are high temperature (fever), severe and consistent cough, and serious breathing problems in severe cases, however, complications result in the serious inflammation of the lungs, and organ malfunction occurs in patients with comorbidities and health conditions especially diabetes, heart disease and obesity. With high virulence and contagious nature of SARS-CoV-2, over 11.4 million confirmed cases and over 533,780 deaths have occurred as a result of COVID-19 globally, with over 6.1 million recoveries as of 6 th July 2020. Presently, there is no known cure for COVID-19, however, remdesivir has been approved for emergency use for the treatment of COVID-19 patients by the Food and Drug Administration, a United States federal regulatory body (FDA), while various clinical trial treatments and vaccines are being tried globally. The world is faced with containing the spread of the infection, and this review revealed that thorough hand washing with antiseptic soap and running water and usage of alcohol hand sanitizer, frequent surfaces cleaning, strict adherence to social distancing, regular respiratory hygiene, wearing of protective face masks, frequent testing, self-isolation, quarantine and rigorous contact tracing will help to prevent further spread, and control the transmission of the viral pathogen. It is however strongly recommended that only the strict compliance to the mitigative and preventive measures provided above will yield the desired results in the prevention, management and control of the COVID-19 pandemic.

Background: Examination stress is caused by various stressors: the fear of inadequate preparation for the exam and fear of failing it, the need to pass very well in the exam to satisfy the parental and guardian expectation and the extra effort made to work harder, burning the midnight oil over the preparation for the examination. The aim of this study is to use the data of blood pressure to find out the effect of examination stress on the various Nigerian secondary school classes. Method: Quasi experimental research design was used for this study, A sample of (650) respondents was selected using stratified sampling technique. Digital sphygmomanometer was used to measure the actual blood pressure readings of the respondents. The readings were taken twice on each occasion with at least thirty minutes interval in sitting positions. The measurements were carried out three times during the study, two weeks after resumption for the second term of 2017/2018 academic year, two weeks before the second term examination and four weeks after the terminal examination. Results: The results show that the mean systolic blood pressure two weeks before the start of the examination is generally higher for all the classes than their values at the beginning of the term and their values at four weeks after the examination. Since blood pressure increases with stress . Conclusion: examination stress increases towards the start of examination and reduces after it, males and females differ in their experience of stress imposed by academic examination, and blood pressure increases with stress.

Background: The aim of this study was to examine the factors predicting the acceptance of COVID 19 vaccines in West Africa, with a focus on Nigeria. Four (4) hypotheses were posed for this study. Methods: This study employed a descriptive method design. The sample size was comprised of 32,224 respondents, all Nigeria citizens. A multistage sampling technique was employed for the survey involving quantitative data. A questionnaire was used as the instrument for data collection. The data collected for this study were analysed using both descriptive and inferential statistics (t-test and ANOVA). Results: The findings of this study revealed that there is a significant difference in COVID-19 vaccine acceptance based on age F (9, 32214) = 812.114, P<0.05, ƞ2=0.1849; based on gender differences t = (32222) = -21.808, P<0.05; based on religion t = (32222) = --75.228, P<0.05; and based on income F (4, 32219) = 740.394, P<0.05, ƞ2=0.084. Conclusion: The findings of this study show that there is a significant relationship between age, gender, religion, income and the acceptance of COVID-19 vaccines in Nigeria. The findings further show that men are more vaccine-hesitant than women; older people find it easier to accept vaccination; Christians are more likely to accept COVID-19 vaccines than people from other religions. It is therefore recommended that religious leaders should be well educated on the health benefit of the COVID-19 vaccination and that the government should put more effort into improving the economy of the country so that the individual income can improve.
