It is interesting that all the zero Covid proponents have completely forgotten about Netherlands.
A few days ago every single twitter enthusiast advocating for zero Covid was adamant that Dutch restrictions were ineffective and Netherlands did a fatal mistake by not re-instating indoor mask mandates. It is worth noting that Netherlands government and health advisors were always skeptical about masks and only introduced them under populist pressure. They changed the rules earlier this year - masks are now only required on public transport and planes.
The fast drop may also be a "temporary blip" but the Netherlands case trajectory looks very good. Netherlands vaccination rates are similar to the UK (a few percentage points lower for second doses). They have also made the decision to delay vaccinating non-CEV teenagers.
