Rare case of homozygous ifnar1 deficiency in a samoan child with disseminated varicella after vaccination

Autosomal recessive interferon alpha/beta receptor 1 (IFNAR1) deficiency increases susceptibility to live-attenuated vaccines and wild-type viruses. Currently 16 cases, half with Polynesian ancestry have been reported since the discovery in 2019. Most cases present with severe MMR or yellow fever vaccine-related disease. Some cases report severe SARS-CoV-2, herpes simplex, and enterovirus. Varicella vaccine-related disease has been hypothesized but not previously reported.
