A World Health Organisation expert on vaccines has said people should feel reassured that even if health authorities find a link between blood clots and the AstraZeneca jab, such cases are “very rare”.

Dr Kate O’Brien, who heads the WHO’s department of immunisations and vaccines, said the UN health agency and the European Medicines Agency (EMA) are investigating the possibility of a link.
