Ireland is suspending use of the Oxford/AstraZeneca vaccine against Covid as a precautionary measure following further reports of blood clots in people who have received it, this time from Norway.

The deputy chief medical officer, Dr Ronan Glynn, said Ireland’s advisory body on vaccines had recommended that deployment of the AstraZeneca jab should be “temporarily deferred” with immediate effect. He stressed, though, that there was no proof that the vaccine had caused blood clots.

The pause in Ireland’s use of the AstraZeneca vaccine came as the head of the UK’s Office for National Statistics, Prof Sir Ian Diamond, said he had “no doubt” there would be a further wave of coronavirus infections in the autumn.

His comments on the BBC’s Andrew Marr Show echoed warnings from England’s chief medical officer, Prof Chris Whitty, who has said there are risks in reopening society and that the UK will experience another surge of cases at some point, potentially in late summer or through the autumn and winter.

We had to understand the data around the “wonderful” vaccine rollout, said Diamond. “But having said that, we need also to recognise that this is a virus that isn’t going to go away. And I have no doubt that in the autumn there will be a further wave of infections.”

The first reports of blood clots in people receiving the AstraZeneca vaccine came out of Austria and caused a flurry of concern, leading to a number of European countries, including Denmark, pausing their use of it pending investigations.

Ireland cited the report into a death and three hospitalisations in Norway, which came out on Saturday.

Prof Karina Butler, the head of Ireland’s National Immunisation Advisory Committee (NIAC), said it acting out of an abundance of caution but wanted to know more about the unexpected cluster of “very serious” clotting events in younger people – Norway said this happened in people under 50. In three cases, these had involved clotting in the brain. In one of them, it was fatal.

There were similarities to other cases reported elsewhere in Europe, she said. It was necessary to know “was there a possibility of a relationship with the vaccine, something which was rare but very serious and could have significant outcomes”, she told Virgin Media News.

The agency did not yet know whether more blood clots are happening than expected in the population generally. “But they do seem to have clustered together at a level and in younger people – I mean less than 65 – where we wouldn’t necessarily have expected them to happen and thus the question was should we just pause until we get that information, because above all we want to maintain confidence in the vaccine programme so that people can feel that what they are getting is safe, that any serious safety signal is being thoroughly investigated,” she said.

In a statement, Glynn said:

“It has not been concluded that there is any link between the Covid-19 vaccine AstraZeneca and these cases. However, acting on the precautionary principle, and pending receipt of further information, the NIAC has recommended the temporary deferral of the Covid-19 Vaccine AstraZeneca vaccination programme in Ireland.

Millions of people have had the AstraZeneca jab without any significant side-effects, the UK’s Medicines and Healthcare Products Regulatory Authority (MHRA) has said. Very rare events cannot be detected in clinical trials, however, which involve tens of thousands of people given a jab.

The Norwegian Medicines Agencysaid the four people under 50 who had the AstraZeneca jab all had a reduced number of blood platelets. It added: “People under the age of 50 who have received the AstraZeneca vaccine and feel increasingly unwell more than three days after vaccination, and who notice larger or smaller blue spots in the skin (skin haemorrhages) must consult a doctor or out-of-hours medical service as soon as possible.

“Similar incidents have been reported in other European countries, and the European Medicines Agency (EMA) is considering whether there may be an association with the coronavirus vaccines. So far, no conclusion has been reached.”

The MHRA said there was no reason to pause use of the vaccine in the UK. “We are aware of the action in Ireland. We are closely reviewing reports but given the large number of doses administered, and the frequency at which blood clots can occur naturally, the evidence available does not suggest the vaccine is the cause,” it said.

AstraZeneca vaccinations make up almost 20% of the 570,000 shots administered in Ireland, mainly to healthcare workers after its use was not initially recommended for those over 70.

A spokesperson for the company said that there had been no signal from their clinical trials or their own safety data covering more than 17m doses of an increased risk of pulmonary embolism, deep vein thrombosis or thrombocytopenia.” In fact, the reported numbers of these types of events for AstraZeneca jab recipients were lower than the number that would have occurred naturally in the unvaccinated population, he said.
