Previous infection with an Omicron variant of COVID-19 did not protect seniors in long-term care and retirement homes from getting reinfected within a few months, a new study published Monday has found.
In a recent study published in the journal Eurosurveillance, researchers investigated whether prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and/or coronavirus disease 2019 (COVID-19) vaccination protected against SARS-CoV-2 Omicron variant of concern (VOC) BA.4/5 sub-VOC or BA.2 sub-VOC infections.
In a recent study published in the Emerging Infectious Disease journal, researchers compared the neutralization associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.5 sublineage to Omicron BA.1/BA.2 sublineages among vaccinated and convalescent patients.
