I think there's something fishy going on with VIC testing.
8 people at a drinks party 12 days ago. All close contacts.
2 unvaxxed and 6 double dose.
Guy who brought it to party was Pfizer jabbed and felt he was hit by a bus.
4 x AZ jabbed had mild cold symptoms for 2/3 days. Then clear.
1x AZ was very bad for 3 days then recovered but he is a smoker.
1 unvaxxed had mild cold symptoms and the other unvaxxed had nothing.
However at testing:
Pfizer guy goes positive with home RAT followed by positive PCR.
After notifying others they all go to get tested some RAT some PCR,
All AZ tested negative but waited up to 6 days for the PCR results? They've all done 6 days iso before even getting results? All had symptoms and all are emphatic they had Covid, but all test negative?
Perhaps the samples lose efficacy if they are left too long before testing.
