On Tuesday, Davis – who hosts Dragons’ Den – said he was “living the story” after surge testing in the area where he lives revealed he had the virus.

He added he has “a record of assiduous mask-wearing and I’m weeks beyond my second vax”.

“Haven’t sat indoors at a bar or restaurant since March 2020,” he added.

He went on to say he has “a record of assiduous mask-wearing and I’m weeks beyond my second vax”.

“Haven’t sat indoors at a bar or restaurant since March 2020,” he added.

With just two days before most Covid rules are lifted, Dr Arthur Hosie, a microbiologist at Staffordshire University, answers questions for The Mirror on what really is the most effective Covid jab.

If you’re double-jabbed can you still catch coronavirus?

Yes. No vaccine is 100% effective. So although your chances of catching the infection are decreased, this is still possible.

This is why it is important that those who are double dosed still need to pay attention to other mitigations to prevent transmission.

Factors such as patient age, underlying health conditions and the length of time since vaccination all play a role.

If you’re in one of the vulnerable categories but double jabbed, is it safe to see relatives such as grandchildren, who have yet to be vaccinated?

It is certainly safer than it was before you were double jabbed, providing you have allowed sufficient time since you received the second dose.

But it is not without risk. Therefore, it is wise to take precautions such as meeting outdoors or in well-ventilated buildings and encouraging all to take a lateral-flow test prior to meeting.

Are your chances of getting Covid different, depending on which vaccine you have had?

There is no data that would support this. There are different numbers quoted about the vaccine efficacies for different vaccines but the three in use in the UK have broadly similar efficacies.

If you catch it but are double-jabbed, can it still be fatal? Does the type of vaccine you’ve had affect how ill you might be?

Sadly, there have been fatalities in those who are double-jabbed but this is far rarer than in the single-jabbed or non-vaccinated groups. Typically, the symptoms will be less severe. There is less data available on the impact on Long Covid.
