J Allergy Clin Immunol Pract. An official website of the United States government. The tests were able to detect more dilute solutions of Delta samples than Omicron samples, suggesting that the tests may be less sensitive to the new variant, Dr. Tromberg said. Once inside the muscle, the vaccine triggers an immune response. Salivas advantages may be more pronounced with Omicron, which appears to replicate more quickly in the upper respiratory tract and have a shorter incubation period than earlier variants.
