Announcements

World Immunization Week, celebrated annually during the last week of April, is a global health awareness initiative highlighting the critical role of vaccines in protecting people of all ages against vaccine-preventable diseases.

On this momentous occasion, we are thrilled to present a thoughtfully selected compilation of articles and Special Issues that focus on the pioneering research and cutting-edge strategies in immunology and vaccination. We encourage readers to delve into these scholarly contributions and stand with us in our commitment to preserving and enhancing global immunization health.

Join us as we explore the latest findings and innovative methods that are shaping the future of immunization. Together, we can strive towards a world where every individual has access to the life-saving benefits of vaccines.

We hope that the established journals in the fields of biology life sciences and medicine and pharmacology at MDPI will provide a communication platform for innovative ideas regarding prevention and treatment.
