[Combined or coadministred Measles, Mumps, Rubella and Varicella Vaccines? That is the question!].

In November 2011, the Medicine's Italian Agency published the Pediatric Working Group's recommendation; that is do not use the quadruple vaccine against measles, rubella, mumps and varicella as first dosage in children from 12 to 23 months, because it involves an increase of febrile convulsions risks. It caused a big discussion between international and national Scientific and Institutional Bodies. In Italy, varicella is the most common vaccine preventable disease and preventive measures are not uniform. Clear and universally accepted indication is needed.
