Navigating Rotavirus Vaccination: A Global Perspective on Progress and Challenges

Rotavirus infection is a significant cause of childhood morbidity and mortality, resulting in severe diarrhea, dehydration, electrolyte imbalances, and metabolic acidosis in infants and young children (1). The destruction of enterocytes following rotavirus infection can lead to malabsorption, which is the inability to absorb nutrients from the intestines. Gastroenteritis may also be a risk factor for developing inflammatory bowel disease (IBD), and gastrointestinal infections can exacerbate colitis in patients with existing IBD (2). Rotavirus remains the leading cause of diarrheal deaths globally, accounting for nearly 19.11% of such deaths in 2019 (3). Global statistics reveal that 80% of rotavirus-related deaths occur in developing nations. Notably, India, Nigeria, Pakistan, and the Democratic Republic of Congo, continue to account for a substantial portion of rotavirus deaths (4). While the overall Age-Standardized Death Rate (ASDR) has declined, regional variations persist, with Africa, Oceania, and South Asia facing a considerable burden that requires a nuanced approach to public health strategies(3).
