[Contraindications to vaccinations: no news is good news].

: Contraindications to vaccinations represent an extremely debated topic. In this paper the literature revision is presented, taking into account different vaccines and aspects related to allergies. There were no significant differences compared to the Guide to contraindications to vaccinations, edited in 2009. Therefore, only a revision including new available vaccines and an updating of the citations would be necessary. This revision should be intended as an opportunity to renovate the Guide, transferring it on an informatics platform. This should enhance the usability and facilitate a constant update of the Guide.
