More than one million people have been vaccinated in the UK so far as numbers of coronavirus continue to soar.

NHS England started the mass roll out of vaccinations in December after the Pfizer-BioNTech vaccine was approved.

The second vaccine, developed by Oxford-AstraZeneca, then began its roll-out at the beginning of January.

A third, the Moderna Vaccine is currently being assessed by the MHRA.

Speaking to the BBC’s Andrew Marr on Sunday, Prime Minister Boris Johnson said the end is in sight pledging to vaccinate ten of millions of people in the coming months.

NHS England says the coronavirus (COVID-19) vaccine is safe and effective and gives the best protection against coronavirus.

Here's everything you need to know about the vaccination.

Who is in the priority list for the COVID-19 vaccine?

The NHS is currently offering the COVID-19 vaccine to people most at risk from coronavirus.

The members of the public are in this priority order:

• Residents in a care home for older adults and their carers

• All those 80 years of age and over and frontline health and social care workers

• All those 75 years of age and over

• All those 70 years of age and over and clinically extremely vulnerable individuals.

• All those 65 years of age and over

• All individuals aged 16 years to 64 years with underlying health conditions which put them at higher risk of serious disease and mortality

• All those 60 years of age and over

• All those 55 years of age and over

• All those 50 years of age and over

It is estimated that taken together, these groups represent around 99% of preventable mortality from COVID-19.

The second dose of the vaccine was to be given after 21 days, has that changed?

The latest evidence suggests the 1st dose of the COVID-19 vaccine provides protection for most people for up to 3 months.

As a result of this evidence, when you can have the 2nd dose has changed. This is also to make sure as many people can have the vaccine as possible.

The 2nd dose was previously 21 days after having the 1st dose, but has now changed to 12 weeks after.

How safe is the COVID-19 vaccine?

The vaccines approved for use in the UK have been developed by Pfizer/BioNTech and Oxford/AstraZeneca.

So far, thousands of people have been given a COVID-19 vaccine and reports of serious side effects, such as allergic reactions, have been very rare. No long-term complications have been reported.

How effective is the COVID-19 vaccine?

The 1st dose of the COVID-19 vaccine will give you some protection from coronavirus. But you need to have the 2 doses of the vaccine to give you the best protection.

There is a chance you might still get or spread coronavirus even if you have the vaccine.

How will I know when it is my turn to be vaccinated?

The NHS will send letters inviting people to book their vaccination appointment, the letter could be received from the GP practice or NHS England directly.

This letter will include all the information needed to book appointments, including their NHS number.

The public are being asked not to contact the NHS to get an appointment until they get this letter.

When will I be vaccinated?

It is expected that anyone in the highest risk groups will receive their vaccinations between January and April 2021.

As more vaccines become available, programmes will be expanded.

Where are the vaccinations taking place?

GP Surgeries and hospitals, more sites are expected to open in the coming weeks

Who cannot receive the vaccine?

• Anyone unwell with a fever

• Anyone with a history of immediate onset anaphylaxis

• If you are Pregnant or planning to become pregnant in the next 2 months or breastfeeding

• If you are taking part in a COVID-19 vaccine trial or any other investigation of a medicinal product

• If you have received the flu vaccine in the last 7 days

Can I have the vaccine if I have already had Covid?

Yes, you should get vaccinated.

A new online calculator can predict when you are likely to receive the Covid-19 vaccine in 2021.

Omni’s website hosts a calculator which will inform users how many people in the UK are likely to be ahead of them in the queue for the jab.

The coronavirus vaccine queue calculator asks a series of questions including your age, profession and whether you have any underlying health issues.

Based on the answers provided it can predict how many people in the UK will be ahead of you for the vaccine.

The calculator is completely independent and is in no way linked to the NHS or the Government.
