Background: Messenger RNA (mRNA) vaccines emerged as a powerful tool in the fight against infections. Unlike traditional vaccines, this unique type of vaccine elicits robust and persistent innate and humoral immune response with a unique host cell-mediated pathogen gene expression and antigen presentation.

Methods: This offers a novel approach to combat poxviridae infections.

Article Synopsis
  • - Breast tuberculosis (TB) is a rare form of TB affecting the breast, seen in less than 0.1% of breast conditions in western countries, but more common (up to 3-4%) in TB-endemic areas like Africa and Asia.
  • - A case was reported of a 54-year-old HIV-positive woman with a six-month history of breast masses, initially suspected to be cancer, but was later confirmed to be TB upon histological examination.
  • - The findings highlight that TB symptoms can be non-specific and unusual in HIV patients, particularly in cases of extra-pulmonary TB.

Epstein-Barr Virus (EBV), structurally similar to other herpes viruses, possess significant global health challenges as it causes infectious mononucleosis and is also associated with various cancers. Due to this widespread impact, an effective messenger RNA (mRNA) vaccine is paramount to help curb its spread, further underscoring the need for its development. This study, following an immunoinformatic approach, aimed to design a comprehensive mRNA vaccine against the EBV by selecting antigenic proteins, predicting Linear B-cell epitopes, cytotoxic T-cell lymphocyte (CTL) and helper T-cell lymphocyte (HTL) epitopes, and assessing vaccine characteristics.

Background: The safety of the COVID-19 vaccines has been a topic of concern globally. This issue of safety is associated with vaccine hesitancy due to concerns about the adverse effects of the vaccines. Consequently, this study determined the short-term safety profile of the Oxford/AstraZeneca COVID-19 vaccine in Ekiti State, Nigeria.

Introduction: Diabetes mellitus (DM) is an important global public health challenge, and the burden of the disease is huge, particularly in low- and middle-income countries (LMICs), where the majority of people with this condition reside. Undiagnosed DM is more prevalent in LMICs. The aim of this study is to determine the prevalence and associated factors for DM in Ekiti State.

  • Mpox is a zoonotic disease due to the Mpox virus, which was first noted outside its typical regions in Central and West Africa on May 21, 2022.
  • A study involving 647 patients across 16 countries found the majority of cases were young males, mostly homosexual-bisexual, with symptoms like rashes, fever, and lymphadenopathy.
  • The findings highlight the need for increased awareness and swift public health responses to manage Mpox’s spread beyond endemic regions.

Hepatitis B virus (HBV) infection follows a natural course of events predicted by a dynamic interaction between viral antigen and the host immune system, which forms the basis for HBV serological diagnosis. These interactions may deviate from the typical serologic patterns. This study investigates the types of atypical HBV serologic profiles (AHBSP) across clinical cohorts of patients with HBV infection in southwestern Nigeria.

Introduction: Although vaccines are the safest and most effective means to prevent and control infectious diseases, the increasing rate of vaccine hesitancy and refusal (VHR) has become a worldwide concern. We aimed to find opinions of parents on vaccinating their children and contribute to available literature in order to support the fight against vaccine refusal by investigating the reasons for VHR on a global scale.

Methodology: In this international cross-sectional multicenter study conducted by the Infectious Diseases International Research Initiative (ID-IRI), a questionnaire consisting of 20 questions was used to determine parents' attitudes towards vaccination of their children.

The development of potent antiretroviral drugs has significantly reduced morbidity and mortality associated with human immunodeficiency virus infection, however, the effectiveness of these medications depends upon consistent daily oral intake. Non-adherence can lead to the emergence of resistance, treatment failure and disease progression. This has necessitated the development of long-acting antiretroviral formulations administrable via an infrequent dosing regimen.

The approval of vaccines for emergency use signifies a great milestone to end the COVID-19 pandemic. However, less than 2% of the global vaccines have been administered in Africa, putting the continent in a precarious situation in the eventuality of another wave that may consume its health system. There is still an enormous task in Africa in the face of vaccine nationalism.

Article Synopsis
  • Hepatitis B virus (HBV) affects around 2 billion people worldwide, leading to about 800,000 deaths annually from liver-related diseases, with significant prevalence in sub-Saharan Africa where many people also have HIV.
  • A study screened 250 HIV/AIDS patients for HBV, finding an 8% co-infection rate, and compared their serological profiles to HBV-only patients, highlighting key differences.
  • The study revealed that the average age of HIV/HBV co-infected individuals was higher (45.5 years) than those with only HBV (30.5 years), with a higher percentage of females in the co-infected group, and shown variations in serological markers like HBeAg and H

Unlabelled: The widespread of coronavirus (COVID-19) is a new global health crisis that poses a threat to the world. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originated in bats and was discovered first in Wuhan, Hubei province, China in December 2019. Immunoinformatics and bioinformatics tools were employed for the construction of a multi-epitope subunit vaccine to prevent the diseases.

The pandemic of Coronavirus disease 19 is not abating since the outbreak began in December 2019. Africa is currently experiencing a surge after an initial low incidence and nosocomial infections could be contributing to this. A dominant factor responsible for this is a weak healthcare system because of many years of neglect due to abysmal budgetary allocation to the sector.

Stimulation and generation of T and B cell-mediated long-term immune response are essential for the curbing of a deadly virus such as SAR-CoV-2 (Severe Acute Respiratory Corona Virus 2). Immunoinformatics approach in vaccine design takes advantage of antigenic and non-allergenic epitopes present on the spike glycoprotein of SARS-CoV-2 to elicit immune responses. T cells and B cells epitopes were predicted, and the selected residues were subjected to allergenicity, antigenicity and toxicity screening which were linked by appropriate linkers to form a multi-epitope subunit vaccine.

The COVID-19 infection has been a matter of urgency to tackle around the world today, there exist 200 countries around the world and 54 countries in Africa that the COVID-19 infection cases have been confirmed. This situation prompted us to look into the challenges African laboratories are facing in the diagnosis of novel COVID-19 infection. A limited supply of essential laboratory equipment and test kits are some of the challenges faced in combatting the novel virus in Africa.
