8B people when faced with no food, petrol or electricity can be left to rip each others faces off.

Let's at least get Wimbledon out of the way first.

But why would you grant random access to all and sundry?

Except you can't prevent it as recent years have shown with everyone from the local council and other bodies getting access to confidential information on a person.

There is *always* mission creep and *always* access to more bodies than intended for any electronic information. This is true for everything from local address details to classified military level.
It'll happen.

Then add the risk of IT security and other parities obtaining information via direct or indirect attack on the data itself. Either the backend system or the local device.

The only way to prevent any of that is to not have that information stored at all and only submitted, if required and removing it after the event.

So no, it makes no sense at all to have access which can be abused available at all.

Once that information is made available in that format, you, AND the data controllers themselves have no guarantee of control of who or what can access that data now or in the future.

It's too late to get long-term data, by the time you get it, you're dead.

Ridiculously over-dramatic for a virus that only affects a tiny known demographic seriously.

If they'd waited long enough for Swine Flu vaccine to get long term data less people would have been dead or disabled.
Or Thalidomide.

Although i've got no issue with mRNA vaccines (they're a technological miracle and may well be amazing for cancer treatments), your argument about not waiting for long term data is absurd given the lack of severity of the thing they're there to protect against.

Consent to the purpose is needed except for National security, Crime and taxation and Domestic (i.e my own) purposes. see GDPR and its UK equivalent the Data Protection Act.

So you're safe. Parliament alone can do anything it likes.

So you're safe. Parliament alone can do anything it likes.

Again you're ignoring the governmental decisions taken to massively expand what bodies can get what data. The amount of agencies that can get data has increased 3 fold in recent years with little or no checks and balances

And the unauthorised access issue.

So no, its not safe. Only safe option is to not store it, especially centrally.
