Measles, mumps, and rubella (MMR) vaccine and COVID-19: a systematic review

This study was performed to investigate published literature about the association between measles, mumps, and rubella (MMR) vaccine and COVID-19. This is a systematic review in which the databases of Chocrane, Pubmed, Scopus, Web of Science as well as reliable journals including Lancet, New England Journal of Medicine, Jama and also Centers for Disease Control and Prevention (CDC) publications were searched.Out of 169 documents discovered during the literature review, 56 ones were somehow related to the association between MMR vaccine and COVID-19, of which 11 ones mentioned the association between these two, and 8 of them contained a hypothesis about this relationship. A quasi-trial study reported the positive effect of the MMR vaccine on reducing the severity of COVID-19 symptoms among those who received it. Also, a cross-sectional study showed an association between the level of Immunoglobulin G (IgG) mumps and COVID-19. Moreover, a genomic data analysis study also reported the effect of Rubella Immunoglobulin G (IgG) level on COVID-19. It seems that due to the similarity of respiratory diseases including measles, rubella, and mumps to COVID-19, MMR vaccine should be investigated more deeply to see if it is effective in order to deal with this novel disease.
