Blood clotting cases have concerned authorities across Europe, who have identified a loose association with the AstraZeneca jab. They have reacted with caution, attaching age limits to

dosages. The UK has followed suit, leading to warnings about compliance should ministers attempt to "walk back" advice. Although national authorities still assert the Covid jab is

safe and effective, the Joint Committee on Vaccination and Immunisation (JCVI) has led with caution. New Government policy will limit AstraZeneca rollout to over-30s only, with everyone

under the threshold offered an alternative. Authorities have advised GP-led sites to cancel incoming appointments for this same group. Professor Wei Shen Lim, The JCVI's COVID-19 Chair,

said his organisation wanted a safety-first approach. READ MORE: WHAT DOES IT FEEL LIKE WHEN YOU HAVE A BLOOD CLOT? But he added there is a clear benefit for the "majority of the

population". He said in a statement: "Safety remains our number one priority. "Based on the available data and evidence, JCVI has advised that it is preferable for adults aged

under 30 with no underlying conditions to be offered an alternative to the AstraZeneca vaccine where available. "This weighs up the risks of being seriously ill or dying from COVID-19

against the extremely small risk of a serious adverse event." Speaking to Express.co.uk, Dr Charlie Easmon, director of Your Excellent Health Service, said the AstraZeneca

vaccine's reputation has suffered in the UK. He added the Government risks low public compliance if it walks back its advice. Dr Easmon said: "I think the AZ vaccine has lost this

race in the UK in that AZ stopped their own trial in the young, and the MHRA and JCVI have advised under 30s be given a different vaccine. "You cannot 'walk back' advice like

that and expect public confidence and compliance." The incidence of thromboembolic events, specifically Cerebral Venous Sinus Thrombosis (CVST), among those who received the AstraZeneca

jab remains low. Just 79 people in the more than 20 million recipients experienced clotting issues. Of those, 19 people have died, while others spent time in the hospital. The Medicines and

Healthcare products Regulatory Agency (MHRA) estimates an incidence rate of four in one million, close to the non-vaccinated average.
