title: [Intramuscular vaccine in infants. Suck or not suck?].
abstract: BACKGROUND
  The administration of vaccines has been and remains one of the most painful medical techniques for children in primary care consultations. When administering vaccines most professionals still breathing before injecting the vaccine for fear of injection into the bloodstream.
  
  
  OBJECTIVE
  To explore the literature to clarify the need to suck or not before injecting a vaccine.
  
  
  METHODS
  Literature review.
  
  
  RESULTS
  two clinical trials and two systematic reviews were reviewed. No side effects were associated with the action of no-aspiration, however pain was higher among those children who received vaccination after aspiration.
  
  
  CONCLUSIONS
  This technique has been described in the literature as responsible for increasing the pain of the child and the mentioned risk is not scientifically proven. Although there is little literature on the subject, evidence suggests that the administration of vaccines must be made quickly and without hope.
