政府、媒体都在号召大家打疫苗,随着Omicron的蔓延,这几个礼拜,看到周围不断有人中招,都是打了疫苗+booster的,感到沦陷到自己头上也是迟早的。
现在越来越多的餐馆、健身房都在要求出示疫苗凭证,似乎有了疫苗卡令人放心了。 真的吗?
实际上,我们目前只是知道疫苗帮助减少得病后的症状,既不防止从别人那里感染上,也不防止从自己身上传染给别人。那么为什么去公共场,非要出示疫苗卡? 疫苗卡不但没有用,反而给别人false sense of security。
Most vaccines that protect from viral illnesses also reduce transmission of the virus that causes the disease by those who are vaccinated. While it is hoped this will be the case, the scientific community does not yet know if the Pfizer-BioNTech COVID-19 Vaccine will reduce such transmission.
