Sin­gle multi-vac­cine break­through

The Press and Journal (Aberdeenshire) - - NEWS -

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

Sci­en­tists from the Mas­sachusetts In­sti­tute of Tech­nol­ogy 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 col­lec­tions of vac­cines be­ing in­cor­po­rated into a sin­gle jab, in­clud­ing boost­ers that are re­leased af­ter a spe­cific time pe­riod.

The re­searchers de­vel­oped the “cups” from PLGA, a bio­com­pat­i­ble plas­tic-like poly­mer al­ready ap­proved for use in med­i­cal de­vices such as im­plants and pros­thetic de­vices.

The re­searchers are now test­ing the de­liv­ery par­ti­cles with a va­ri­ety of drugs in­clud­ing ex­ist­ing vac­cines.
