It is essential to make sure that vaccines are safe, effective, and of good quality. In the past years, there have been some reports of adverse effects regarding vaccination. One of these adverse effects is the development of Stevens-Johnson syndrome. Stevens-Johnson syndrome is a rare, severe, skin disorder, that usually occurs after medication. In Europe, its estimated incidence is of 2-3 cases/million population/year. Therefore, the aim of this study was to investigate, through a systematic review, the association between vaccination and the development of Stevens-Johnson syndrome. We performed a systematic review using PubMed, Scopus and Web of Science databases. We included studies dated between January 2000 and February 2018. The main selection criterion was the reporting of the disease, following vaccination. Ten studies were selected, from a total of 391 studies. Of these, 5 were case reports, 3 were cohort studies and 2 were case-control. All the studies were regarding cases of Stevens-Johnson syndrome after vaccination. The selected studies reported cases following vaccines such as influenza vaccine, smallpox, anthrax and tetanus vaccine, MMR vaccine, varicella vaccine, DTaP-IPV vaccine or rabies vaccine. None of the cohort studies reported statistically significant associations between vaccination and the syndrome. In the case-control studies, it was not observed significant increased risk for the Stevens-Johnson syndrome following the administration of vaccines. Regarding the case reports, there was not sufficient evidence to form a positive association between these two factors, and more studies are needed. In this review it was not possible to establish a positive relation between vaccination and the development of Stevens-Johnson syndrome.
