Disparities in COVID-19 vaccine coverage across the globe have uncovered inequities in global healthcare. While more than half of the population of the developed countries have been fully vaccinated, only a small percentage of the African population has received one vaccine dose so far, a far cry from the global vaccination targets. Furthermore, several low and middle income (LMICs) African countries lack the competence, infrastructure, logistics, and financial resources to mass-vaccinate their populations. This paper highlights the causes and implications of the low COVID-19 vaccine coverage on Africa and the global community, and discusses strategies for restructuring and strengthening COVID-19 vaccination in Africa.

Introduction: Understanding caregiver willingness to participate in pediatric clinical research is needed. We examined caregiver perceptions of pediatric clinical research during COVID-19 and examined research attitudes and sociodemographic factors as predictors of willingness.
Methods: A cross-sectional telephone survey was administered to caregivers of children from August 2020 to April 2021.

Background: The innate immune response is important for the development of the specific adaptive immunity, however it may also be associated with reactogenicity after vaccination. We explore the association between innate responsiveness, reactogenicity, and antibody response after first COVID-19 vaccination.
Methods: We included 146 healthy Dutch individuals aged 12-59 who received their first BNT162b2 (Comirnaty, Pfizer) COVID-19 vaccination.

Over the last decade, mRNA vaccines development has shown significant advancement, particularly during the COVID-19 pandemic. This comprehensive review examines the efficacy of pivotal vaccines against emerging COVID-19 variants and strategies for enhancing vaccine effectiveness. It also explores the versatility of mRNA technology in addressing other infectious diseases such as influenza, respiratory syncytial virus, HIV, cytomegalovirus, Ebola, Zika, Rabies, and Nipah viruses.

The recent expansion of mpox in Africa is characterized by a dramatic increase in zoonotic transmission (clade Ia) and the emergence of a new clade Ib that is transmitted from human-to-human (H2H) by close contact. Clade Ia does not pose a threat in areas without zoonotic reservoir. But clade Ib may spread widely, as did the clade IIb that since 2022 has spread globally among MSM.

Background: Disease severity and pregnancy outcomes following SARS-CoV-2 reinfections in pregnancy are not well understood.
Methods: We linked women aged 18 to 50 years testing positive in the community for COVID-19 between April 2021 and March 2022 to hospital, vaccine and maternal services databases. We compared hospital and intensive care unit (ICU) admission rates following infection and reinfection in pregnant and non-pregnant women, and low birthweight, prematurity and stillbirth in women infected and reinfected during pregnancy.
