说到超买，就要提到说英语的阿根廷：加拿大
虽然加拿大完全无法研发制造任何武汉肺炎疫苗，口罩也无法达到充份量产供应医护，彻底
的伸手牌；但是加拿大官方自己说自己在国际上订了3亿3千8百万剂的各家武汉肺炎疫苗：

本文节录：
Moderna, which will supply up to 56 million doses of its messenger RNA (mRNA) va
ccine candidate mRNA-1273.
Pfizer, which will supply up to 76 million doses of its mRNA vaccine candidate d
eveloped with BioNTech, BNT162b2.
Medicago, which will supply up to 76 million doses of its virus-like particle va
ccine candidate.
AstraZeneca, which will supply 20 million doses of its viral vector vaccine cand
idate AZD1222.
Sanofi and GlaxoSmithKline, which will supply up to 72 million doses of their pr

Johnson & Johnson, which will supply up to 38 million doses of its viral vector
vaccine candidate Ad26.COV2.S.
Novavax, which will supply up to 76 million doses of its protein subunit vaccine
candidate NVX-CoV2373.
加拿大人口3400万人，订了将近3亿4千万剂的量，算起来一个人大概可以打十剂。而澳洲人
口2600万人，订购8000万剂，大概一人打3剂，算是很厚道了。XD
只是呀！就算订再多排挤到其它国家下单，厂商交货还是自己就国家优先。加拿大实际上目
前总共只拿到不到112万剂，少到目前无法执行一人两剂：

各省政府建议两剂施打间隔为42-90天，远长于厂商建议的14-28天。
所以讲白一点，全世界短时间内都不可能有足够的疫苗，口罩、肥皂洗手、酒精还是目前实
际解。
疫苗的话，还是自己生产最可靠，要不然就会出现加拿大这种状况：除了当伸手牌以外，完
全无解。
