CALGARY -- Alberta’s top doctor confirms 10 people connected to COVID-19 Delta variant outbreaks at Calgary’s Foothill Medical Centre were fully immunized before testing positive for the disease.
“What we're monitoring now is whether or not they had, as we would expect, a milder course of illness,” said Dr. Deena Hinshaw, Alberta’s chief medical officer of health, during Thursday’s provincial COVID-19 briefing.
According to Alberta Health Services, one dose of an mRNA vaccine — like Pfizer and Moderna— offers 73 per cent protection against the alpha variant. That immunity bumps up to 91 per cent with a second dose.
When it comes to the Delta variant strain, first identified in India, a first dose offers 33 per cent protection, and second dose 88 per cent. “While we can see a few cases that have broken through the vaccine, the vast majority of people who are vaccinated will have protection,” said Hinshaw. As of Wednesday, AHS confirms 16 cases of the B.1.617.2 variant in patients on two units at Foothills Medical Centre. Six healthcare workers have also tested positive for the variant.
The hospital has experienced several outbreaks over the course of the pandemic, but this is the first involving the Delta variant. The hospital remains open and has capacity to treat all patients, though AHS said the two units affected by the outbreaks are not accepting admissions. Patient transfers to long-term care centres from the two units with the Delta variant are also on hold.

根据阿省卫生官的说法,打了一针mRNA疫苗后,对印度变种(Delta毒株)提供有33%的保护率, 而打满两针对防护率为88%。
现在他们正在检测这10人病患的情况,看重症转化率为多少。 如果10人都是轻症,证明疫苗有效。
目前尚不清楚这10人是否具有传染性。

那不是阿省研究结果,好像是卡塔尔研究结果。 但是33%保护率没有说打针多长时间,是不是14天后,第一针刚打对alpha变种也只有40%不到 这10个人也没说打针多长时间后。

就是说疫苗有时间限度吗?不够一年吗

关于delta的情况,看新加坡数据就知道了。 两针后的人一百多个得的,99%都是无症状或者轻症。依然有效,只是确实降低了。三哥每次一出手就是来个大的

新闻都说过无数次了,没有变种的都不是100%保护,何况变种的。
