Vaccine breakthrough cases in Washington State to 25th August 2021
This week’s update from Washington State showing vaccine breakthrough cases and which Sars-CoV-2 variant is causing them up to 25th August 2021. It looks like Washington State have spent the last week cataloguing Delta samples from the previous week, as very few new breakthrough cases have been recorded this week.
Although Delta breakthroughs have seemingly increased over the week, they have mostly been moved from the “other” row where they were posted last week into the Delta column this week, as we predicted they would be last week.
We will continue to reprint these figures as long as Washington State continues to publish them, but, sadly, their value is increasingly doubtful due to an obvious lag in sequencing the samples.
