Wir hätten es dann mit einer Variante zu tun, die vom Potential her die vorherigen Infektionswellen in Bezug auf Anstieg und Inzidenzwerte bei gleichen Lockdown-Maßnahmen wie Kindergeburtstage aussehen lassen. Wenn dann noch eine etwas erhöhte Letalitätsrate hinzu kommt und dies auf eine psychologisch ausgelaugte Gesellschaft trifft ...

Und haben wir es mit ein solchen Variante zu tun?
Why emergence of Delta variant is a ‘game-changer’ for Covid recovery around the world
There have been at least 15 cases of the more infectious Delta strain detected in Victoria’s West Melbourne cluster, as well as up to 85 cases of the Kappa strain, which is a closely related variant. NSW also confirmed a case of Delta on Thursday.
Both strains are more infectious than the Wuhan wild-type virus that spread through Australia last year. The Delta strain in particular is worrying experts and is likely to become the dominant strain around the world.
“It completely changes the game,” Melbourne University epidemiologist Professor Tony Blakely said of the Delta variant.
Und weiter:
The appearance of the Delta variant also means increased pressure on Australians to get vaccinated with at least two doses as soon as possible.
Getting two doses of the vaccine has also become more important as neither the AstraZeneca or Pfizer vaccines have been found to work well against Delta if only one dose is given.
Even after two doses are administered, the vaccines are less effective against protecting against the Delta variant than the Wuhan wild-type or the Alpha variant, which was first identified in the UK.
When it comes to the Alpha variant, both AstraZeneca and Pfizer were found to offer about 50 per cent protection against symptomatic disease four weeks after just one vaccine dose, according to figures from Public Health England published in a pre-print paper this week.
But protection against the Delta variant dropped to 36 per cent for those who got the Pfizer jab, and 30 per cent for those who got AstraZeneca.
Fortunately, protection increases substantially once people have had two shots of either vaccine.
All das ist wenig beruhigend denn die Doppel Dosis von Impfung bringt etwas mehr Schutz aber nicht mehr und es ist notwendig das unsere Bevoelkerungen flaechendeckend 2 Impfungen erhalten wobei Pfizer mehr Schutz bietet als Astra Zeneca
