SARS-CoV-2 Variants: Everything you need to know

01 Feb 2023

The COVID-19 pandemic continues to evolve with the emergence of new SARS-CoV-2 variants. The variants of concern have the potential to impact the transmissibility, virulence, and clinical presentation of the disease, affecting the epidemiology, public health measures, and diagnostic and therapeutic options. Mutations in the spike protein of the virus have increased its ability to infect humans and evade neutralization by natural or immunisation-induced antibodies. The highly mutated Omicron variant of SARS-CoV-2 has multiple sublineages with varying transmissibility and immune evasion potential. Pre-exposure prophylaxis plays a crucial role in protecting the immunocompromised populations against severe disease; however, the rapidly changing landscape of the variants poses a major challenge to the current and future effectiveness of pre-exposure prophylactic monoclonal antibodies.
