It's the plausible deniability card but I think there may also be another reason for it.
When over 70s were getting the vaccine and dying a few days later, it was easy to explain it away as a coincidence. Even with over 50s it was possible to use the 'coincidence, not related' excuse, because normie sheep are completely brainwashed. However, when 13 year olds start dying a few days after getting the vaccine, even normie sheep start to ask questions. They don't want the sheep waking up, and kids dying would inevitably start a mass awakening.
