"To make head to head comparisons, they have to be studied at the same time, in head-to-head trials," Adalja said.

That has not happened. Researchers studying the real-world use of Pfizer's and AstraZeneca's vaccines in Britain reported earlier this month that both lowered the risk of hospitalization and death in people 80 and older -- the group by far the most likely to die from infection.

The preprint study done by a team at the University of Bristol found the Pfizer/BioNTech vaccine was 71.4% effective in preventing hospitalizations and the Oxford/AstraZeneca vaccine was 80.4% effective in preventing hospitalizations in patients well into their 80s.

英国自己的研究，如果这个是真的，打了第一针没有血堵的还是打第二针吧

印度生产的，有啥问题，质检不够严格？

安省的严重不良反应报告统计，每十万剂，辉瑞和欧洲AZ1.2，M1.5-1.8，印度AZ略高，4-6。
