加拿大华人论坛 加拿大生活信息预计数日内本省会收到新款新冠疫苗

在加拿大

BC省首席卫生官Bonnie Henry表示，一种新型的新冠疫苗将很快在本省推出。她指，这款蛋白质亚单位疫苗Novavax将在未来几天运到。加拿大卫生部描述为包含无害和纯化的病毒蛋白质是为接种者触发免疫能力抵抗病毒。

卫生部表示，这些类型的疫苗已经在本国使用，其中一个例子是乙型肝炎疫苗。Henry上周提及Novavax新冠疫苗获联邦卫生部批准使用，认为是好消息，可以为注射第一剂mRNA疫苗後出现严重不良反应的人士提供更多选择。

评论
Novavax目前仅被批准用於成人，但在临床试验中，第二次注射後一周的有效性为90%。卫生部指，此款疫苗需要注射唡针，唡针相间大约三星期。

有关部门提醒有意接种此款疫苗的人士可以致电1-833-838-2323。Henry说，目前已经有近1000人登记，疫苗一到达，就会作出安排。

这款疫苗技术比mRNA疫苗成熟，安全性会更好。

相信大家以前都打过乙肝疫苗吧。和这款用的是同一种技术，比较成熟。这有篇英文文章解释了：http://www.theatlantic.com/health/archive/2021/06/novavax-now-best-covid-19-vaccine/619276/


In this context, the success of the Novavax vaccine should be A1 news. The recent results confirm that it has roughly the same efficacy as the two authorized mRNA vaccines, with the added benefit of being based on an older, more familiar science. The protein-subunit approach used by Novavax was first implemented for the hepatitis B vaccine, which has been used in the U.S. since 1986. The pertussis vaccine, which is required for almost all children in U.S. public schools, is also made this way. Some of those people who have been wary of getting the mRNA vaccines may find Novavax more appealing.The Novavax vaccine also has a substantially lower rate of side effects than the authorized mRNA vaccines. Last week’s data showed that about 40 percent of people who receive Novavax report fatigue after the second dose, as compared with 65 percent for Moderna and more than 55 percent for Pfizer. Based on the results of Novavax’s first efficacy trial in the U.K., side effects (including but not limited to fatigue) aren’t just less frequent; they’re milder too. That’s a very big deal for people on hourly wages, who already bear a disproportionate risk of getting COVID-19, and who have been less likely to get vaccinated in part because of the risk of losing days of work to post-vaccine fever, pain, or malaise. Side effects are a big barrier for COVID-vaccine acceptance. The CDC reported on Monday that, according to a survey conducted in the spring, only about half of adults under the age of 40 have gotten the vaccine or definitely intend to do so, and that, among the rest, 56 percent say they are concerned about side effects. Lower rates of adverse events are likely to be a bigger issue still for parents, when considering vaccination for their children.
