The bacillus Calmette\u2010Gu\u00e9rin (BCG) vaccine has beneficial off\u2010target effects that might impact recurrence of HSV infections. In this systematic review, Medline, EMBASE, and PubMed were searched in June 2020; 16 articles were deemed relevant comprising eight animal and eight human studies (301 patients). In animals, BCG administration led to a 1.9 to 5.5\u2010fold increase in survival rate following HSV challenge (vaginal, corneal, or intraperitoneal inoculation). This beneficial effect was influenced by the dose of BCG (higher better), mode of administration (intradermal better than intraperitoneal), and the interval between vaccination and viral challenge (at least 6\u2009days required). In nonrandomized human studies (that failed to control for a placebo effect), BCG vaccination appeared beneficial in 78% of adults with recurrent herpes genitalis or labialis, with 37% being recurrence\u2010free for an extended period, 41% experiencing less frequent or severe episodes, and only 22% reporting no change. This clinical benefit is consistent with the findings of immunological sub\u2010studies. In the two studies restricted to recurrent herpes labialis, 94% appeared to benefit from BCG. The one randomized controlled trial used an intervention in the control group that has immunomodulatory effects thus limiting interpretation. In conclusion, BCG vaccine is a potential, safe, affordable and readily available candidate intervention to decrease the high burden of disease associated with HSV infection and recurrences, but properly controlled randomized trials are required.<\/jats:p>","DOI":"10.1002\/rmv.2151","type":"journal-article","created":{"date-parts":[[2020,9,25]],"date-time":"2020-09-25T05:47:24Z","timestamp":1601012844000},"page":"1-9","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Does bacillus <scp>Calmette\u2010Gu\u00e9rin<\/scp> vaccine prevent herpes simplex virus recurrences?
