The REal-time Assessment of Community Transmission−1 study monitored the spread and clinical manifestation of SARS-CoV-2 monthly in the population in England between 1 May 2020 and 31 March 2022. Loss of sense of smell and taste and cold-like symptoms were less and more predictive of swab positivity for Omicron than for other variants, respectively. Specifically, Omicron infections were not so strongly associated with anosmia as previous variants. Likely, alterations in the viral gene sequences that regulate host responses in individuals infected with Omicron reduced the downregulation of expression of olfactory receptors, which caused anosmia following COVID-19.

Mucosal TLR2-activating protein-based vaccination induces potent pulmonary immunity and protection against SARS-CoV-2 in mice - Nature CommunicationsCurrent vaccines against SARS-CoV-2 reduce mortality but are less effective in preventing infection. Here the authors show that intranasal vaccination with a subunit vaccine including an TLR2-stimulating adjuvant induces strong neutralising antibody and T-cell responses against SARS-CoV-2 in the lungs that protect against infection.
