WITH the need to retest 1.7 million vaccine doses - and delays to doses arriving from India - many people will be concerned about when they will now be invited to have their jab.

Health secretary Matt Hancock told MPs the vaccine supply in April will be "tighter" when there are around 12 million second doses that need to be delivered to the public.

He said: "In the last week, we've had a batch of 1.7 million doses delayed because of the need to retest its stability [...] and we have a delay in a scheduled arrival from the Serum Institute of India."

It is believed the delayed supply from the Serum Institute - amid claims of a block on exports by India's government - totals five million doses of the Oxford-AstraZeneca vaccine.

While it's not possible to get an exact idea of where your place in the queue for the jab lies - especially an estimate that takes into account these new delays - there is an online calculator to give you a rough idea if you're getting impatient to have your shot in the arm.

The Omni Calculator tells users how many people in the UK are likely to be in front of them in the queue for the jab, including when they could expect to receive their vaccine.

It's been popular for a while but it's worth checking in on it again if you're interested, as the Government is aiming to get all over-50s vaccinated by the end of April.

Vaccine queue calculator questions

The Vaccine Queue Calculator asks a series of questions, such as your age, if you are a frontline worker and if you live in a care home or work in one.

It adds if you are pregnant (or plan to be in the next three months) it is not recommended to currently have the vaccine, but states this advice could change when further trial data is available.

On their website, it says the results are worked out based on the Government's nine-point priority list and the likely rate of vaccination.

In simple mode, the tool assumes at the current rate 2.9 million people will be vaccinated a week, however this can be changed in custom mode.

The website highlights it has based its results on the assumption 70.6 per cent of the UK's population will accept the jab, using "the figure last year for people aged 64 and over who were offered the annual flu vaccine".

What happens after you answer the questions?

The calculator gives you a time range of when you might expect to be called in for the vaccine.

This is usually quite a rough estimate - perhaps of around a month - or, as our example shows below, a period of three months or more.

The NHS has warned of a month-long "significant reduction" in weekly supply of vaccines in a letter to local health leaders.

However, drug companies Pfizer and AstraZeneca both said they remain on course to meet their delivery commitments and denied they were facing disruption in supplies.

So, thousands of people are still searching for the calculator online, even if it only offers an approximate idea of vaccine timings.

Not an official calculator

According to the Evening Standard, the calculator is independent and not connected to the NHS or the vaccine rollout programme.

Omni Calculator claims to have "the most unique, crazy, knock-your-socks-off calculators on the web".

The public can use it to work out itching questions from how many years of your life you can save by picking a bike over a car to their cooking calculators.
