The Medicines and Healthcare products Regulatory Agency on Thursday said it had received no such reports of clotting events following use of the vaccine made by BioNTech SE and Pfizer Inc.
"Until the appropriate data is available, STIKO recommends for people under 60 years old that instead of the second AstraZeneca dose, a dose of an mRNA-vaccine should be given 12 weeks after the first vaccine", STIKO said.
Professor Kidd said expected side effects from either the Pfizer or AstraZeneca jab could include fever, sore muscles, tiredness and headache and that such symptoms could start about 24 hours after receiving the vaccine and last one to two days.
He said: "The extreme rarity of these events in the context of the many millions of vaccine doses that have been administered means that the risk-benefit decision facing people who are invited to receive Covid-19 vaccines is very straightforward: receiving the vaccine is by far the safest choice in terms of minimising individual risk of serious illness or death".
"The number and nature of suspected adverse reactions reported so far are not unusual in comparison to other types of routinely used vaccines", the MHRA online statement said.
MELBOURNE, April 2 ― Australia is investigating whether a blood clotting case recorded today is related to the AstraZeneca coronavirus vaccine, a health official said, raising concern in a nation where most people are expected to receive the drugmaker's shot. The agency issued the guidance after some European countries, including Germany and France, suspended its use over blood clot fears. In total, some 400,000 people were given the AstraZeneca vaccine during the period the problems were reported. That followed reports of 31 cases of the rare clots, mostly in women.
People who have tested positive for coronavirus within the past six months will only have to have one dose of vaccine, public health institute RIVM said on Friday.
CVSTs are inherently more common in younger women and taking the pill increases the risk.
The head of the European Medicines Agency (EMA) has said that there is "no evidence" to support restricting the use of the AstraZeneca vaccine in any population. Canada recently received a shipment of 1.5 million doses of the AstraZeneca vaccine from the United States as part of a "vaccine loan" agreement.
The previously delayed shipment of 600,000 Moderna vaccine doses will arrive on Friday, with deliveries beginning on Saturday, the government's vaccine distribution czar, Canadian Army Major General Dany Fortin said.
