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& #39;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
