原来这疫苗并不能防止人感染病传播病毒,只是减缓感染后的伤害
https://www.abc.net.au/news/health/2021-02-16/covid-19-how-long-will-coronavirus-vaccines-last-australia/13130530 6park.comWill the vaccine protect from COVID straight away?No. You will need two doses of the vaccine to be properly protected.
And it's worth remembering that the vaccine won't necessarily stop you from getting COVID and spreading it, but will help your body not to get sick if you do contract it.
意思就是说假使全国50%的人口已经打好疫苗了 这50%的人仍然可以染病并且传给另外的50%人口,只是没打疫苗的会有更重的症状更高的死亡率 6park.com 这么说用疫苗来扑灭病毒理论上也是不可能的了?
