Moderna booster side effects: 9 common symptoms of Covid vaccine – and how long they last

The UK’s Covid-19 booster vaccination drive is being accelerated in response to the outbreak of the Omicron variant, with all adults now eligible for a top-up dose.

The UK government is aiming to offer a third jab to all over 18s by the end of the year as part of a “national mission” to boost immunity levels this winter.

The urgent call to get vaccinated comes after coronavirus infection levels hit record highs, with people told to prioritise events that matter to them this Christmas as part of effort to minimise the spread.

Further restrictions are not expected to be made before Christmas Day as it is hoped current measures, including mandatory face masks, stricter isolation rules and Covid passes, coupled with the booster rollout will avoid the need for a full lockdown.

The national booking system for boosters is now open to all adults, with people able to get a jab if it has been at least three months since they had their second dose.

Walk-in centres have also been opened to allow people to get their jab without the need for an appointment as the NHS races to vaccinate as many people as possible,

If you are eligible to get a booster dose, you will be offered either the Moderna or the Pfizer vaccine.

As with the first and second doses, it is common to experience some mild side effects afterwards, but symptoms should usually only last for a few days.

If you are given the Moderna vaccine, these are the most common side effects to expect.
