Responding to dynamic global threats, vaccines for emerging and re-emerging infectious diseases focus on pathogens with epidemic potential such as Ebola, Nipah, and chikungunya. These diseases often surface in vulnerable regions where healthcare infrastructure is limited. Rapid vaccine design, field-ready delivery, and regulatory harmonization are central to mitigating outbreaks. Technological platforms like mRNA, VLPs, and viral vectors are being deployed for speed and adaptability. Cross-sector collaboration is vital to preclinical pipelines, clinical trials, and emergency use readiness. As the frequency of zoonotic spillover rises, vaccines for emerging and re-emerging infectious diseases represent critical investments in pandemic preparedness and global security.
