Abstract

Background: Vaccine-induced phantosmia is a rare adverse effect of vaccination and has not been previously reported related to the Johnson & Johnson (J&J) COVID-19 vaccine.

Case presentation: Three weeks after receiving the J&J COVID-19 vaccine, a 39-year-old veteran started smelling a burning odor in the absence of an identifiable source. At presentation to the clinic, his general and neurological examinations, brain magnetic resonance imaging, and electroencephalogram were all unremarkable. The episodes persisted for nearly 2 years (21 months postvaccination).

Conclusions: This is the only case of phantosmia reported after the use of the J&J COVID-19 vaccine and aligns with the literature that reports 1 case of phantosmia and 2 cases of hyposmia following the Pfizer-BioNTech COVID-19 mRNA vaccine. This information will help health care professionals understand the possible adverse effects of COVID-19 vaccination and be better equipped to counsel patients about the benign but potentially long-lasting adverse effects of the J&J COVID-19 vaccine.

新冠肺炎疫苗接种后的嗅觉幻觉。

背景：疫苗诱导的幻视症是一种罕见的疫苗接种不良反应，此前尚未报道与强生新冠肺炎疫苗有关。病例介绍：在接种强生新冠肺炎疫苗三周后，一名39岁的退伍军人在没有可识别来源的情况下开始闻到燃烧的气味。在诊所就诊时，他的全身和神经系统检查、脑磁共振成像和脑电图都不明显。发作持续了近2年（接种疫苗后21个月）。结论：这是使用强生新冠肺炎疫苗后报告的唯一一例幻视症病例，与Pfizer-BioNTech新冠肺炎mRNA疫苗后报告1例幻视和2例尿道下裂的文献一致。这些信息将帮助卫生保健专业人员了解新冠肺炎疫苗接种可能产生的不良影响，并更好地为患者提供关于强生新冠肺炎疫苗的良性但潜在的长期不良影响的咨询。
