Population-based risk compensation may have been a driving force in UK's COVID pandemic

The COVID-19 pandemic has irreversibly altered our lives in many ways. However, available COVID vaccines are effective against (symptomatic) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, hospitalizations, and even death. Despite a diminishing protective effect against infection and onward transmission after vaccination, and a slightly diminished effect with the Delta variant compared to the Alpha variant, protection against severe outcomes remains high.

UCLA study shows how COVID vaccination is critical to controlling the pandemic

A study currently available on the medRxiv* preprint server has demonstrated that the incidence and mortality rates of coronavirus disease 2019 (COVID-19) in the US can be significantly reduced at the population level by increasing vaccinate rates from 40% to 80%.
