The kids are off to school. Fingers crossed. It was quiet at the bus and on the bus. I guess most parents decided to drive their kids to school for the first day as only 4% opted for online learning. We normally bring them their the first day as well, yet since 'kiss and drop' is closed we're expecting quite a bit of chaos there (bad street layout, not much parking, 2 big schools in the same location, now both starting at the same time). They'll be fine on the mostly empty bus until it can get to the school.
Oddly quiet in here this morning lol.
And now the wait starts for the schools to close. Predictions are dire and here's one of the reasons why vaccines aren't able to stop the spread

The Delta variant may have taken over as quickly as it did not only because of an increased infectivity, but because it is less affected by neutralizing antibodies produced by prior infection with COVID-19 or produced by vaccines, according to a new study that looked at the variant in a lab setting.
In the study, compared to the original strain of the virus that emerged in Wuhan, China, the Delta variant was found to be six times less sensitive to neutralizing antibodies from those who had recovered from COVID-19, and eight times less sensitive to antibodies produced in response to two doses of Pfizer-BioNTech or AstraZeneca vaccines.
It has still proven to prevent severe disease (in a recent U.K. study, out of more than 950,000 people who had received two shots, only 0.2 per cent had a breakthrough infection afterwards), but I guess not effective enough to stop you from passing Delta along while vaccinated. Just like asymptomatic cases before could still pass it on.
Another aspect of the study involved replicating the human airway in a laboratory model. Researchers found that the Delta variant could reproduce faster and more efficiently in this environment than the Alpha variant could, described in the study as having a “significant replication advantage.”
Booster shots will be needed, with some tweaks to new variants, basically like the yearly flu shot
“Strategies to boost vaccines responses against variants are warranted and attention to infection control procedures is needed in the post vaccine era,” the study concluded.
