疫苗由于具有预防和治疗传染病的作用 ,多年来人们一直致力于疫苗的研制和开发 ,但传统的疫苗一般需要多次注射才能达到良好的免疫效果 ,这是导致许多发展中国家的免疫覆盖率低的主要原因。因此近年来 ,科学家们致力于单次免疫疫苗的开发 ,其中疫苗控释微球的开发研制前景广阔 ,它的研制成功和广泛应用将有助于提高传染病高发国家的免疫覆盖率。本文对疫苗控释微球的制备和应用研究概况进行综述
Vaccines Because of their role in the prevention and treatment of infectious diseases, vaccines have been developed and developed over the years, but traditional vaccines generally require multiple injections to achieve good immunization, leading to immunization coverage in many developing countries Low main reason. Therefore, in recent years, scientists are committed to the development of a single immunization vaccine. Among them, the development of vaccine controlled-release microspheres has broad prospects for development. Its successful development and extensive application will help to improve the immunization coverage of infectious disease-prone countries. This review summarizes the preparation and application of vaccine controlled release microspheres
