The update comes after the Welsh Government announced a change in the roll out of the AstroZeneca jab in Wales on Friday.

People under the age of 40 will now be offered an alternative vaccine to the Oxford vaccine as a "precautionary measure" following a change in advice from the Joint Committee on Vaccination and Immunisation (JCVI) and The Medicines and Healthcare products Regulatory Agency (MHRA).

Previously, the MHRA has said the balance of risk for the AstraZeneca vaccine against Covid is very favourable for older people but “more finely balanced” for younger groups, who do not tend to suffer serious coronavirus illness.

A spokesman for the Welsh Government said the change is not likely to lead to a delay to the vaccine programme in Wales.

The statement added: "Everybody who has already had a first dose of the AZ vaccine should be reassured that they should receive a second dose of the same brand, irrespective of age, in line with JVCI advice. Medical exemptions may apply to a very small minority.

"The AstraZeneca vaccine has already saved thousands of lives and remains safe and effective for the majority of the population. Over 1.2million people have received the AZ vaccine in Wales since January, with very few cases of the rare clotting with thrombocytopenia event.

"Vaccines remain the best way out of this pandemic and provide strong protection against Covid-19 – it is important that when people are called forward, they should get their jab. To date, over 1.8million people in Wales have received a first dose of vaccine and a further 800,000 have also received a second dose."

People as young as 18 have been getting their vaccines in Wales this week and all eligible adults are on track to be fully vaccinated by the end of July.

The infection rate across Wales now stands at 9.8 cases per 100,000 people for the seven days up to May 1 – as low as it was at the end of August last summer.
