Sage adviser claims ministers trying to get as many as possible infected with Covid
Exclusive: Prof Robert West says rhetoric about caution is a way of putting blame on public
A scientist advising the government has accused ministers of allowing infections to rip through the younger population in an effort to bolster levels of immunity before the NHS faces winter pressures.
The allegation comes after Englands remaining Covid restrictions were eased on Monday, with nightclubs throwing open their doors for the first time in the pandemic and all rules on social distancing and mask wearing dropped even as infections run high.

What we are seeing is a decision by the government to get as many people infected as possible, as quickly as possible, while using rhetoric about caution as a way of putting the blame on the public for the consequences, said Prof Robert West, a health psychologist at University College London who participates in Sages behavioural science subgroup.
It looks like the government judges that the damage to health and healthcare services will be worth the political capital it will gain from this approach, West said, adding that ministers appear to believe the strategy is now sustainable unlike last year because of the vaccine rollout.
