During the throes of the COVID-19 pandemic, Anne Moscona didnt feel safe going to a restaurant or catching a flight. Sci. The primary endpoint of the CARVIN study was the assessment of virus load kinetics of SARS-CoV-2 by determining the presence and amount of viral carriage via PCR. Additionally, safety follow-ups were performed at 2 time-points. Because we get infected with SARS-CoV-2 primarily by breathing it in, a nasal spray might be an easy and efficient way to offer protection against the virus, especially in crowded places.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the etiological . Secondary endpoints included the assessment of symptoms, patient status (using a 11-category ordinal score as proposed by the WHO11), body temperature and blood oxygen saturation, quality of life (reported in the SF-36 generic quality of life questionnaires) and safety (adverse events, including worsening of patient status/symptoms) over time. Many elderly people as well asindividuals who are immunodeficient for various reasons do not respond to vaccines, and are in the need of other protective measures, said Kalle Saksela, MD, PhD, senior author of the study and a virologist at the University of Helsinki.

It has been suggested that azelastine can inhibit the entry of the SARS-CoV-2 into the nasal mucosa by binding to the ACE2 receptor and also act via binding to the main protease of SARS-CoV-2 and to the host cells sigma-1 receptor, therewith facilitating both viral entry and replication-inhibiting effects6,9.
