BioNTech-Pfizer 和 Moderna 对COVID 19近期的数据比较

之前，BioNTech说他们的疫苗对于Delta是有效的，无需更改处方。而刚刚有报道把BioNtech疫苗和Moderna的对delta病毒作比较。大家估一下那个更为有效？

BioNTech said its vaccine developed with Pfizer works against the Delta strain and does not need to be modified yet. They have shipped around 1 billion doses of their vaccines to more than 100 countries, and expect to generate US$33.5 billion in sales this year!

A recent Mayo study (in July, in Florida) shows that the risk of suffering a breakthrough COVID-19 infection with the delta variant after being fully vaccinated with the Moderna vaccine may be much lower than the risk for those who received the Pfizer vaccine! The risk of a breakthrough case was 60% lower for Moderna recipients as compared to Pfizer recipients. Another study (in Minnesota) also shows that Moderna vaccine was 76% effective at preventing infection, but the Pfizer vaccine was 42% effective. (1)

报道指Moderna疫苗是较为有效。其实，Pfizer-BioNtech也不差。
