Sorry, you are right. I didn't see the possible misinterpretation.
Am concerned what will happen in September in schools, the GF is a teacher in a group of schools that don't seem to have a joined up plan or process for covid. Seeing as this is where I caught covid from, I am concerned.
Looks like two double vaccinated people I know have had positive PCR tests. This does concern me.

Well, first of all none of the vaccines are 100% effective (and never will be).
A vaccine with 97% efficacy doesn't mean that everyone who eventually gets it will only have symptoms 3% as bad as if they weren't vaccinated. Nor does it mean that 97% of people will never get an active infection. Nor does it mean that 97% of people will never exhibit symptoms. Understanding how vaccine efficacy is measured is the key to understanding what it really means.
Timing is important too, a mate of mine has tested positive and has mild symptoms despite being double jabbed, but he started to come down with symptoms 3 or 4 days after his second jab, so he only really had the benefit of the initial jab 8 and bit weeks ago. (To be clear, he was told to self-isolate after a mate of his he'd been on a night out with had tested positive, and also get his own test, his symptoms started two or three days into his self-isolation.)
Secondly, the virus has to get into the body and start being replicated for the body to begin to mount its immune response, so it's unsurprising that double-jabbed people (even with a 100% effective vaccine) could have subsequent positive PCR tests.
Some people seem to believe that immunity takes the form of some magic barrier that prevents them from ever being infected again. It doesn't work that way.
The question, in these individual cases, is how much/well/fast does the vaccine stimulated immune response suppress the infection and suppress any (and hopefully all) symptoms.
Lastly, the PCR test is sensitive enough that a nasal swab could be picking up just enough virions to trigger a positive PCR test result even though no virus particles have actually got into the body yet (if you still consider the inside of the nostrils as "external").
(This is similar to the doubters testing random objects for Covid-19 and reporting that a piece of fruit had tested positive for Covid-19. It's not a really a test for Covid-19 as that's the disease that's caused by the virus. The PCR test is a very sensitive test for the presence of the specific coronavirus RNA, it's not a test for the specific disease, but a positive PCR test in a human has a very strong correlation with a Covid-19 infection.)

I'd disagree. The title/headline alone makes it sound like the change is going to happen now, or very soon.
It's not, it's a proposed change for the new school year starting in September.
Who knows what the Covid infection situation will be in two months after a whole load of non-school related mixing (summer holidays, holiday camps, etc).
Any problems with year wide bubbles being taken out because of the current rules is only going to get worse over the remaining 3 and a bit weeks of term due to both the countrywide growth in cases and also due to some kids deciding to have fun and deliberately submitting positive results in order to get themselves out of school.
