CW that’s interesting could you post a link to that article so I can have a read.
The way I understand the vaccine works is that you get little immunity in the early days of receiving the vaccine and then after 10 days the immunity stated by the supplier is achieved, obviously not the full two jab protection. So it would follow that catching the virus is still possible in the early days and even after the stated 10 days. The difference is if you catch the virus after the 10 days your body will have produced antibodies to help you fight it resulting in fewer serious health issues.
Could you tell us when, within the two weeks, the cases appeared?
As I said the vaccine, even after two doses, is unlikely to stop you getting the virus it justs helps protect your body from the effects.
