The object
Ana Jaklenec co-developed polymer microparticles engineered to release vaccine doses at planned intervals from one injection. MIT identifies her as a principal investigator and senior author on the 2025 work, while its technology office lists her on micromolded pulsatile-release vaccine formulations.
What Ana did
Co-developed programmable polymer vaccine microparticles with Robert Langer and their MIT team.
Why it matters
The physical microparticle system packages an immunization schedule into a manufactured injectable material, potentially reducing missed booster doses where follow-up care is difficult.
Living-status check
MIT reported Jaklenec's active principal-investigator role and senior authorship on 15 May 2025, with a November 2025 feature describing her fabrication of the vaccine microparticles.
