Posterior Pharyngeal Follicles in a Woman with Breakthrough SARS-CoV-2 Infection.

Abstract

A 24-year-old previously healthy female nurse working in a surgical ward who had received the second dose of BNT162b2 (Pfizer-BioNTech COVID-19 vaccine) 2 months earlier presented with a 1-day history of fever and sore throat. On examination, she had a body temperature of 38.3°C and an oxygen saturation level of 96% breathing room air. Her pharynx was swollen and erythematous, with small red follicles on the posterior wall (Figure 1A). She tested positive for SARS-CoV-2 and negative for 21 other respiratory viruses/bacteria on a BioFire Respiratory 2.1 Panel (bioMérieux, Marcy-l’Ėtoile, France). She was diagnosed with COVID-19 and hospitalized.
