Pre-existing anti-SARS-CoV-2 immunity decreases viral spread but increase SARS-CoV-2 Omicron competitiveness in hamsters

In a new study, researchers assessed the impact of pre-existing immunity against SARS-CoV-2 acquired by previous infections (PI) or COVID-19 vaccination on the transmission of SARS-CoV-2 variants of concern such as Delta and Omicron.
