health authorities in the uk and europe have confirmed a possible link between the astrazeneca covid-19 vaccine and a small number of blood clot cases, but are yet to establish a definite causal relation. according to the mhra, the risk of a serious blood clot as a result of the jab is approximately one in 250,000 people vaccinated, or four in a million.
and when they do, there could still be considerable uncertainty involved, as was stated.” it has also been widely noted that the risk of blood clots for those taking the contraceptive pill is around one in 2,000 – significantly higher than the risk for people receiving the az vaccine, but cases are still so rare that no restrictions have been placed on prescribing the pill to healthy people. in addition to uk and eu health authorities advising that people continue to get vaccinated, the world health organisation (who) has said in a news briefing that the benefits of the az jab continue to outweigh the risk of rare side effects. the az jab has been proven to provide near-total protection against severe disease and death from covid-19, and therefore also against the blood clots those with the virus are at risk of experiencing.
the team – in cardiff and the us – have shown in exquisite detail how a protein in the blood is attracted to a key component of the vaccine. however, concerns about rare blood clots shaped how the vaccine has been used around the world including an alternative being offered to the under-40s in the uk. the vaccines used in the uk all try to deliver a snippet of the covid-virus’s genetic code into the body to train the immune system. the researchers thought the adenovirus might be linked to the rare clots occurring in some people. so they used a technique called cryo-electron microscopy to take images of the adenovirus in molecular-level detail.
it is thought the body starts to attack platelet factor four after confusing it for part of the foreign adenovirus to which it is stuck. these clots, known as vaccine-induced immune thrombotic thrombocytopenia, have been linked to 73 deaths out of nearly 50 million doses of astrazeneca given in the uk. astrazeneca said the vaccine is thought to have saved more than a million lives around the world and prevented 50 million cases of covid. a spokeswoman for astrazeneca stressed that clots were more likely to occur because of a covid infection than the vaccine, and that the complete explanation for why they occur had not yet been established. a university of oxford spokesperson said: “we continue to follow with interest any new developments and investigation into potential causes for these very rare side effects associated with the vaccine, whilst being reassured by real-world effectiveness data that the vaccine remains a highly effective tool for combating this pandemic.” the cardiff team hope their findings can be used to improve adenovirus-based vaccines in the future to reduce the risk of these rare events.
over 20 million doses of the az vaccine have been given in the uk so far. according to the mhra, the risk of a serious blood clot as a result of there has been a link established between the astrazeneca vaccine and a very rare but serious side effect called thrombosis in combination covid-19 is associated with a risk of hospitalisation and death. the reported combination of blood clots and low blood platelets is very rare,, .
scientists believe they have found “the trigger” that leads to extremely rare blood clots after the oxford-astrazeneca covid vaccine. 2.7 million people have received the az/oxford vaccine there, and 31 patients have been identified with cerebral venous thrombosis. blood clots are uncommon in young people, and it’s even rarer to see haematologist mitesh borad at the mayo clinic in phoenix, arizona,, .
