The vagaries of the COVID-19 market and the uncertainties of pandemic fatigue are hitting some biopharma companies in the pocketbook, at least for now. Due to lower-than-expected revenues from its COVID-19 Comirnaty vaccine and antiviral Paxlovid (nirmatrelvir/ritonavir), Pfizer Inc. reduced its 2023 revenue guidance by $9 billion after hours Oct. 13, saying it now anticipates full-year 2023 revenues to range from $58 billion to $61 billion – down from its previous guidance range of $67 billion to $70 billion.

In a study published in Nature on Oct. 11, coinciding with the beginning of IDWeek 2023 in Boston, researchers from Harvard Medical School described EVEscape, a method for anticipating the movements of SARS‑CoV‑2 by predicting potential mutations likely to escape current vaccines and treatments.

Due to the continual emergence of SARS-CoV-2 mutants, there is an unmet clinical need for broad-spectrum treatments for COVID-19. A potential target for novel treatments is the S2 subunit of the SARS-CoV-2 spike (S) protein, which has been highly conserved across the different variants of the virus.

Recently, researchers at Cincinnati Children’s Hospital, in collaboration with colleagues in Japan, have developed a human vascular organoid model that accurately mimics the vascular damage caused by SARS-CoV-2.
