Israel's COVID-19 vaccine rollout being monitored closely in Montreal

News out of Israel that the first dose of the Pfizer-BioNTech vaccine may not be as effective as initially hoped has caused ripples of concern among Montreal's medical community.

On Monday, Israel’s so-called coronavirus czar, Nachman Ash, reportedly said the first dose of the vaccine appeared “less effective than we had thought.” In remarks reported by Army Radio, Ash added that the protective effect of the vaccine against SARS-CoV-2, the virus that causes COVID-19, was “lower than Pfizer presented.”

“the U.K.’s Joint Committee on Vaccination and Immunization concluded that the efficacy of the vaccine was 89 per cent, starting 14 days after the first dose.”

But a “real world” analysis of the vaccine by Clalit, Israel’s largest health provider, has found that the chance of a person being infected with the coronavirus dropped by 33 per cent 14 days after they were given the first shot. The Times of Israel reported that another health provider, Maccabi, observed the vaccine caused a 60 per cent drop in the chances of infection after the first dose.

Quebec vaccine plan may be rethought after troubling Israeli data, says provincial adviser

Quebec could change its vaccine strategy based on discouraging new data out of Israel about the efficacy of the first dose, on its own, of the Pfizer COVID-19 vaccine, says a top adviser in the province.

Data on 200,000 elderly Israelis suggests that the first shot alone only lowered infections by 33 per cent—about a third of the roughly 90-per-cent rate that many experts around the world have predicted.

今天早上新闻里有位医生说，老人的免疫系统不如年轻人，辉瑞的有效率数据是整个年龄段的综合数字。

看来老年人应该按辉瑞的要求在21天之内打第二针，不能像前一阵子有的省份要把间隔延长到40多天。

看来老年人应该按辉瑞的要求在21天之内打第二针，不能像前一阵子有的省份要把间隔延长到40多天。

另一个可能是年轻人打了疫苗以后，有了部分保护，然后感染了也是无症状，结果就没有包含在辉瑞的测试中间， 而老年人抵抗力弱，依然有症状

以色列一花独秀，已经接种超过人口37%，非常希望里见成效，可是现在还很不明显，昨天死亡人数还突破纪录多达1/3，达到100人，上次纪录远在4月19日，73人。

死亡大多是老年人，而老年人应该是最先接种的，按照道理应该老年已基本接种了。
不过从感染到死亡应该有个很长时间，所以现在还不能说明问题。
估计最多三个月后，就可以看出疫苗的实际有效性

死亡的是否都是接种以后被感染的？

死亡的是否都是接种以后被感染的？

这没法知道，以色列从12月20日开始，到现在正好1个月。至于死亡的病人的细节，不知道。

希望疫苗不断发生效力，也许还需要一段时间，才能看出明显效果。

咱村目前疫苗供应紧张。想打都没。

Dr. Fauci says new data shows Covid vaccines appear to be less effective against some new strains

Even if the vaccines are less effective against new variants, they'll still likely provide enough protection to make them worth getting, Dr. Anthony Fauci said.

Dr. Fauci says Covid vaccines appear to be less effective against some new strains​

• Early data shows that the Covid-19 vaccines on the market may not be as effective in guarding against more contagious strains of the coronavirus, Dr. Anthony Fauci said on Thursday.
• Even if the drugs are less effective, they will still likely provide enough protection to make the vaccines worth getting, he said.
• A dip in the vaccines’ effectiveness would be “all the more reason why we should be vaccinating as many people as you possibly can,” Fauci added.
