The official guidance states: “Most people who are eligible for the flu vaccine can have it.

“You only cannot have the vaccine if you’ve had a serious allergic reaction to a previous dose of the vaccine or an ingredient in the vaccine. Some of the flu vaccines used in the UK contain egg protein. Tell the person vaccinating you if you have an egg allergy.”

The vaccination may trigger some adverse effects, though these ought to be minor and improve within one to two days. This might involve tenderness at the injection site, general muscle pain and a slightly elevated temperature.

The flu jab typically requires up to a fortnight to become effective, and there remains a possibility you could contract flu following vaccination, but this will probably be a less severe form of the illness and can assist you in recovering more quickly.

The NHS observed: “Protection from the flu vaccine goes down with time and the types of flu virus the vaccine protects against are updated each year. This is why it’s important to get the flu vaccine every year.”
