Sci­en­tists de­velop tech­niques for vac­cines in one jag

The Courier & Advertiser (Dundee Edition) - - NEWS -

A multi-jab that could pack­age the en­tire range of child­hood vac­cines in a sin­gle in­jec­tion may be on the way.

Sci­en­tists in the US are de­vel­op­ing a new method of con­tain­ing vac­cines in mi­cro­scopic sealed “cof­fee cups”.

They are de­signed so that their “lids” de­grade at spe­cific times, al­low­ing the con­tents to spill out.

The tech­nol­ogy could lead to a col­lec­tion of vac­cines be­ing in­cor­po­rated into a sin­gle jab, in­clud­ing boost­ers that are re­leased af­ter a spe­cific time pe­riod.

Lead sci­en­tist Pro­fes­sor Robert Langer, from the Mas­sachusetts In­sti­tute of Tech­nol­ogy, said: “We are very ex­cited about this work be­cause, for the first time, we can cre­ate a li­brary of tiny, en­cased vac­cine par­ti­cles, each pro­grammed to re­lease at a pre­cise, pre­dictable time, so that peo­ple could po­ten­tially re­ceive a sin­gle in­jec­tion that, in ef­fect, would have mul­ti­ple boost­ers al­ready built into it.

“This could have a sig­nif­i­cant im­pact on pa­tients ev­ery­where, es­pe­cially in the de­vel­op­ing world where pa­tient com­pli­ance is par­tic­u­larly poor.”
