The Imperial College COVID-19 Response Team in London produced two studies that influenced policy in Europe in a big way. In particular, it helped push Britain to switch its strategy from one based on ‘herd immunity’ to that of "suppression".
(1) March 16: ‘Suppression the only viable strategy’
The first study, published March 16, 2020, concluded that ‘epidemic suppression is the only viable strategy at the current time. The social and economic effects of the measures which are needed to achieve this policy goal will be profound. Many countries have adopted such measures already, but even those countries at an earlier stage of their epidemic (such as the UK) will need to do so imminently.’

(2) March 30: ‘59,000 lives saved in 11 European countries via non-pharmacologial interventions, between 7 to 43 million individuals infected -- as of March 31’
The second study, published March 30, 2020, said that ‘with current interventions remaining in place to at least the end of March, we estimate that interventions across all 11 countries will have averted 59,000 deaths up to 31 March [95% credible interval 21,000-120,000]. Many more deaths will be averted through ensuring that interventions remain in place until transmission drops to low levels.
‘We estimate that, across all 11 countries between 7 and 43 million individuals have been infected with SARS-CoV-2 up to 28th March, representing between 1.88% and 11.43% of the population. The proportion of the population infected to date – the attack rate - is estimated to be highest in Spain followed by Italy and lowest in Germany and Norway, reflecting the relative stages of the epidemics.’
