Testing vaccine candidates quickly with lab-grown mini-organs

Developing and testing new treatments or vaccines for humans almost always requires animal trials, but these experiments can sometimes take years to complete and can raise ethical concerns about the animals' treatment. Now, researchers reporting in ACS Central Science have developed a new testing platform that encapsulates B cells -- some of the most important components of the immune system -- into miniature 'organoids' to make vaccine screening quicker and greatly reduce the number of animals needed.
