My summary of the 4 Phase 3 vaccine trials from their protocols. Some key details of the JNJ analysis plan not included in their protocol released today.

Note the table pertains to Astra Zeneca's US trial, currently on hold. There is an ongoing Phase 3 Astra Zeneca trial moving forward in the UK and many countries.

The primary endpoint defining infections are quite different for each of the 4 trials.
Also please note in the Table that freezing is incorrect, different for JNJ (not deep) but still required, i.e. not isothermal, thanks @carlzimmer for correction

Table updated with correction on freezing (JNJ still requires refrigeration, not isothermal) and 1st interim JNJ look at 20 events, the lowest number of all 4 trials
