Vaccine breakthrough cases in Washington State to 22nd September 2021

This week’s update from Washington State showing vaccine breakthrough cases and which Sars-CoV-2 variant is causing them up to 22nd September 2021.  Vaccine breakthrough cases caused by the Delta variant have increased substantially this week, by just over 500 cases.

As we mentioned in our update last week, the amount of genome sequencing of Sars-CoV-2 samples undertaken by Washington State is decreasing, so the figures below do not represent all vaccine breakthrough cases, just a small percentage.

Vaccine breakthrough cases in Washington State to 15th September 2021

This week’s update from Washington State showing vaccine breakthrough cases and which Sars-CoV-2 variant is causing them up to 15th September 2021.  The Delta variant continues to be the leading cause of breakthrough infections in the state, however a big drop in the number of cases being sequenced means that this data doesn’t have much statistical relevance to the actual number of breakthrough infections occurring.

The data might, however, be a useful indicator of the rising importance of new variants in the future, and on that basis we will continue to publish the information

Vaccine breakthrough cases in Washington State to 8th September 2021

This week’s update from Washington State showing vaccine breakthrough cases and which Sars-CoV-2 variant is causing them up to 8th September 2021.

There is a newer version of this post here

The Delta variant, which now accounts for 72% of all vaccine breakthrough cases in the state, has posted another large increase this week. 423 new vaccine breakthrough cases are listed for Delta, but that number is actually slightly down on last week’s figure of 443 cases.

Vaccine breakthrough cases in Washington State to 1st September 2021

This week’s update from Washington State showing vaccine breakthrough cases and which Sars-CoV-2 variant is causing them up to 1st September 2021. This week, the Delta variant has posted another large increase for vaccine breakthroughs, and, as it is now the predominant variant in the region, will presumably continue to do so for some time to come.

Much of the backlog of virus genome sequencing that built up two weeks ago appears to have been cleared, so there is a big reduction in sequences listed under the “other” category this week. Those sequences have now been largely identified and have moved mostly to the Delta row.

 

There is a newer version of this post here

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.

USA: 20% vaccine breakthrough in Snohomish County, Washington State

“In May 2021, fewer than 5% of cases were among vaccinated individuals. And, in July, now that the Delta’s strain is the overwhelmingly dominant, virus in the community, now 20% of cases in July were among vaccinated people,” said Dr. Chris Spitters, director of the Snohomish County Health District.

Delta vaccine breakthrough cases in Washington State quadruple in two weeks

This week’s update from Washington State showing vaccine breakthrough cases and which Sars-CoV-2 variant is causing them up to 18th August 2021.  The Delta variant is responsible for a big increase in vaccine breakthrough cases reported by Washington State this week. Verified Delta breakthrough cases are up by 219 on last week, but there is real cause for concern for cases with variants that have not been identified by the state – they have increased by 676 in a week!

We are guessing that the 676 breakthrough cases with an unidentified variant are mostly Delta cases. We think that Washington State are now seeing so many vaccine breakthrough cases that they are simply unable to sequence them all in one week.  At least we hope that’s the explanation, because the alternative is that there are unknown Sars-CoV-2 variants in Washington State that are causing far more breakthrough cases than even the Delta variant.

If the unidentified breakthrough cases are mostly Delta, that means the Delta vaccine breakthrough rate has almost quadrupled in 2 weeks.

On the 4th August, there were 405 verified Delta breakthrough cases.

On the 11th August, there were 629 verified Delta breakthrough cases plus perhaps 30 unverified, a total of 659, an increase from the previous week of ~64%.

On the 18th August, there were 848 verified Delta breakthrough cases plus perhaps 710 unverified, a total of 1558, an increase from the previous week of ~150%

USA: At least 125,000 vaccine breakthrough infections, 1,400 dead

At least 125,000 fully vaccinated Americans have tested positive for Covid and 1,400 of those have died, according to data collected by NBC News.  The total number of breakthrough cases is likely higher than 125,683, since nine states, including Pennsylvania and Missouri, did not provide any information, while 11, like Florida, did not provide death and hospitalization totals. Four states gave death and hospitalization numbers, but not the full tally of cases.

USA: vaccine breakthough cases in Washington State by coronavirus variant to 30th June 2021

Washington State has recently published an update on the number of vaccine breakthrough cases. Importantly, it shows which Sars-CoV-2 variant is responsible for 661 of those cases through genome sequencing. This hugely important information is not available for most states in the USA, so the fact that Washington State continues to publish this information for the Covid variants currently circulating in that state makes it all the more valuable.  Spoiler alert: Delta B.1.617.2 is NOT YET the most common variant for vaccine breakthrough cases in Washington State! That situation will almost certainly change over the next few weeks as Delta becomes more dominant across the U.S.

The most common variant currently causing vaccine breakthroughs in Washington State up to 30th June 2021 is Alpha, (B.1.1.7),  at 37%, followed by Gamma (P.1) at 17%. The Delta variant (B.1.617.2) currently only accounts for about 5% of vaccine breakthrough infections.

The Epsilon variant (B.1.429) is showing as being responsible for 15% of all breakthrough cases, yet represents just 3% of the total genome sequences for May to June, and never rose above 10% of genome samples from April 2021.

As you can see, Washington State has recorded 2,228 vaccine breakthrough cases in total which represents a tiny fraction of the 6 million people now vaccinated in that state.

Our thanks to The Washington State Department of Health for providing this vital information.
