Biologically tolerant polymer nanoparticles and hydrogels have been developed that can act as effective adjuvants in vaccines against viral and bacterial infections. These systems provide controlled immobilization of antigens of various natures, increase the stability of vaccine formulations, and significantly enhance the body's immune response.
The Figure shows a diagram of microgel particles as adjuvants.
Innovative materials are highly compatible with tissues and do not cause toxic or inflammatory reactions, making them suitable for a wide range of preventive applications. Thanks to the versatility of their structure and functional groups, such carriers can be adapted to different types of antigens, including protein, polysaccharide, and DNA structures.
The development paves the way for the creation of broad-spectrum vaccines capable of responding quickly to new epidemiological threats and pandemics.
