Realising the potential of SARS-CoV-2 vaccines—a long shot?
The Lancet Respiratory Medicine
… The ability of SARS-CoV-2 vaccines to prevent infection or ongoing transmission remains unclear. The impact of immunisation on hospital admissions will be an important focus as countries aim to keep health-care systems running and protect those most at risk of severe disease in the face of high levels of transmission. Emerging SARS-CoV-2 variants are a cause for concern. New variants include B.1.1.7, which recently emerged in the UK, B.1.351, and P.1. These lineages appear to be more transmissible than previous strains, although there is currently no evidence that they cause more severe disease or compromise the efficacy of available vaccines. Surveillance is needed to detect escape variants at an early stage. New variants also emphasise the ongoing need for public health mitigation strategies and add to the urgency of vaccine rollout across the globe…
