Its a cost-effective way of prevention of disease, mortality, and disability. It is a cost-effective preventive tool and valuable he...
Of course, vaccine-induced immunity is every bit as “natural” as immunity acquired after recovering from COVID-19, with the advantage that vaccine-induced immunity doesn’t require you to suffer through the disease and be at risk for the complications, long term disability, a...
An unseasonably early crush of respiratory viral infections has once again raised the spectre of an “immunity debt,” a concept described by some as an unintended boomerang effect of distancing, masking and other COVID containment measures used to slow SARS-CoV-2’s spread. Experts disagree abou...

[92]. SARS-CoV-2 infection of neurons during the early phases results in anosmia, closely resembling the loss of smell observed after COVID-19 infection. Studies suggest a correlation between disease severity and the viral infective dose in K18-hACE2 mice, which may vary with different virus...
