据媒体获悉,加拿大国家免疫咨询委员会今天将建议55岁以下的人暂停使用牛津-阿斯利康的COVID-19疫苗。


据不愿透露姓名的消息人士说,更新的指南将在今天晚些时候发布,此前在一些接种患者出现罕见的血凝块。


据报道,加拿大预计本周二将收到来自美国的150万剂阿斯利康疫苗。

周一下午,安省首席卫生官Dr. David Williams表示,安省目前已停止为55岁以下人士接种阿斯利康疫苗。


迄今为止,阿斯利康尚未在安省60岁以下居民中接种,因为之前是对60-64岁年龄段的人在药房试点接种该疫苗。


Williams表示,“迄今为止已经接受过该疫苗的人,应该没有任何问题。”


PEI已暂停给18至29岁者接种


加拿大各地目前还没有给55岁以下人士广泛接种这款疫苗。


加拿大东部省份爱德华王子岛今天宣布,已暂停对18至29岁的人群使用牛津-阿斯利康COVID-19疫苗。


爱德华王子岛于3月9日宣布将为在加油站、便利店或超市店工作的18至29岁人士提供阿斯利康疫苗。


此举是因为岛上的COVID-19病例集中于年轻人。


该省表示已收到2,000剂疫苗,并且已分发到全省的药房给年轻工人接种。


建议一改再改


加拿大卫生官员最早建议65岁以下的人群接种阿斯利康疫苗,但3月16日调整建议,称也可以给老年人接种。


加拿大公共卫生局曾表示说,这种疫苗“可能”与“血小板减少症相关的非常罕见但严重的血凝块病例”有联系。加拿大卫生部坚持认为,阿斯利康COVID-19疫苗的益处继续超过风险。

今早,安省卫生厅长Christine Elliott公开在多伦多一家药店接种阿斯利康疫苗。


她上周说:“很多居民对阿斯利康疫苗很犹豫。但其实它安全,有效,可以防止住院并且可以挽救人们的生命。如果我能说服其他人接种阿斯利康疫苗,并且能帮助保护他们以及他们和家人的健康与安全,那么我很乐意这样做。”

Clear link between AstraZeneca and rare blood clots in brain, EMA vaccine chief says​

'In my opinion, we can now say it,' said Marco Cavaleri, chair of the vaccine evaluation team at the European Medicines Agency

There is a link between AstraZeneca’s COVID-19 vaccine and very rare blood clots in the brain but the possible causes are still unknown, a senior official for the European Medicines Agency (EMA) said in an interview published on Tuesday.

“In my opinion we can now say it, it is clear that there is an association with the vaccine. However, we still do not know what causes this reaction,” Marco Cavaleri, chair of the vaccine evaluation team at the EMA, told Italian daily Il Messaggero when asked about the possible relation between the AstraZeneca shot and cases of brain blood clots.

Clear link between AstraZeneca and rare blood clots in brain, EMA vaccine chief says​


Cavaleri added that the EMA would say there is a link although the regulator would not likely be in a position this week to give an indication regarding the age of individuals to whom the AstraZeneca shot should be given.

He did not provide evidence to support his comments.

AstraZeneca was not immediately available for comment. It has said previously its studies have found no higher risk of clots because of the vaccine.

The regulator has consistently said the benefits outweigh the risks as it investigates 44 reports of an extremely rare brain clotting ailment known as cerebral venous sinus thrombosis (CVST) out of 9.2 million people in the European Economic Area who have received the AstraZeneca vaccine.

The World Health Organization has also backed the vaccine.

The EMA said last week that its review had at present not identified any specific risk factors, such as age, gender or a previous medical history of clotting disorders, for these very rare events. A causal link with the vaccine is not proven, but is possible and further analysis is continuing, the agency said.

A high proportion among the reported cases affected young and middle-aged women but that did not lead EMA to conclude this cohort was particularly at risk from AstraZeneca’s shot.

The EMA is expected to give an update of its investigation on Wednesday.

Some countries, including France, Germany and the Netherlands, have suspending the use of the vaccine in younger people while the investigations continue.

Scientists are exploring several possibilities that might explain the extremely rare brain blood clots that occurred in individuals in the days and weeks after receiving the AstraZeneca vaccine.

European investigators have put forward one theory that the vaccine triggers an unusual antibody in some rare cases; others are trying to understand whether the cases are linked with birth control pills.

But many scientists say there is no definitive evidence and it is not clear whether or why AstraZeneca’s vaccine would cause an issue not shared by other vaccines that target a similar part of the coronavirus.

In a separate interview, Armando Genazzani, a member of the EMA’s Committee for Medicinal Products for Human Use (CHMP), told La Stampa daily that it was “plausible” that the blood clots were correlated to the AstraZeneca vaccine.

Some countries limit AstraZeneca vaccine use amid concern over blood clots​

Some countries are restricting use of the AstraZeneca vaccine against COVID-19 while others have resumed inoculations, as investigations into reports of rare, and sometimes severe, blood clots continue.

The European Medicines Agency and the World Health Organization have said the benefits outweigh the risks, but are monitoring the situation.

AstraZeneca said in March its vaccine was 76% effective in preventing symptomatic infections in a U.S. trial, and that studies did not indicate higher risks of clotting.

Oxford-AstraZeneca pauses pediatric trial pending review by UK regulator​

From CNN's Jo Shelley

A pediatric trial of the Oxford-AstraZeneca vaccine has been paused pending a review by the UK’s medicines regulator over rare blood clot cases in adults, a University of Oxford spokesperson told CNN Tuesday.

“Whilst there are no safety concerns in the pediatric clinical trial, we await additional information from the Medicines and Healthcare products Regulatory Agency (MHRA) on its review of rare cases of thrombosis/thrombocytopaenia that have been reported in adults, before giving any further vaccinations in the trial,” the spokesperson said.

“Parents and children should continue to attend all scheduled visits and can contact the trial sites if they have any questions,” they added.

When contacted by CNN, AstraZeneca referred us to Oxford University.

年纪越大预期寿命越短,而且能为国家节约大量养老金……你懂的。



不对,加拿大是从最老的人开始打的。
这是违反自然规律的。
