We propose a simple rule of thumb for countries which have embarked on a vaccination campaign while still facing the need to keep non-pharmaceutical interventions (NPI) in place because of the ongoing spread of SARS-CoV-2. If the aim is to keep the death rate from increasing, NPIs can be loosened when it is possible to vaccinate more than twice the growth rate of new cases. If the aim is to keep the pressure on hospitals under control, the vaccination rate has to be about four times higher…

Relaxing restrictions at the pace of vaccination increases freedom and guards against further COVID-19 waves
Using the age-stratified model and curated epidemiological and vaccination data, it is quantified at which pace European countries can lift restrictions without overwhelming their health-care systems.
Estimating real-world COVID-19 vaccine effectiveness in Israel
Using counts of positive and hospitalized cases of vaccinated individuals, sensitive estimations of the vaccine effectiveness are provided by correcting to daily case incidence, finding high effectiveness of 66-85% in reducing SARS-CoV-2 positive cases and over 90%" in reducing severe hospitalizations.

On March 11, 2020, the World Health Organization declared the spread of a novel coronavirus to be a pandemic. Subsequently, and only 272 d afterward, the Pfizer vaccine started to be applied in the
Containment efficiency and control strategies for the corona pandemic costs
A modified epidemic model is introduced, in which the disease reproduction rate evolves dynamically in response to political and societal reactions, which forms an index that measures the efficiency of containment strategies (the CEI index).
Risk of SARS-CoV-2 infection and subsequent hospital admission and death at different time intervals since first dose of COVID-19 vaccine administration, Italy, 27 December 2020 to mid-April 2021
The results support ongoing vaccination campaigns and support the real-world impact of vaccines on COVID-19 related outcomes.
Impact of vaccination by priority group on UK deaths, hospital admissions and intensive care admissions from COVID‐19
This model suggests substantial reductions in hospital and ICU admissions will not occur until late March and into April 2021 and an inflection point, when 50% of the adult population has been vaccinated, may be a useful point for re‐evaluating vaccine prioritisation.
Tracking the Economic Impact of COVID-19 and Mitigation Policies in Europe and the United States
We use high-frequency indicators to analyze the economic impact of COVID-19 in Europe and the United States during the early phase of the pandemic. We document that European countries and U.S. states
The scale and dynamics of COVID-19 epidemics across Europe
It is found that countries reporting fewer deaths did not generally have intrinsically lower rates of transmission and epidemic growth, and flatter epidemic curves, and countries with fewer deaths locked down earlier, had shorter epidemics that peaked sooner and smaller populations.
Mathematical modelling and projecting the second wave of COVID-19 pandemic in Europe
The time-varying reproduction number of the COVID-19 pandemic has continuously exceeded 1 since 22 June in Spain, 26 June in France and 09 July in the Netherlands, and is estimated to be below 1 based on real-word reported data.
