Despite the benefits, vaccination faces several challenges:
Vaccine hesitancy: Misinformation and distrust can lead to reluctance or refusal to vaccinate. Access and distribution: Ensuring equitable access to vaccines, especially in low-resource settings, remains a challenge. Cold chain logistics: Maintaining the necessary temperature for vaccine storage and transport. Emerging pathogens: Rapidly developing vaccines for new or mutating pathogens (e.g., COVID-19).
