1. Secondary attack rates for Delta for pairs of people who are fully vaccinated with Pfizer. (I’m guessing this is relevant to someone in the Bay, as most of the people you have close contact with for more than 30 mins are fully vaccinated).
2. Long Covid rates for the fully vaccinated (both Delta and other variants).
3. Using genetics or other personal information to estimate risk of severe disease or Long Covid. (e.g. Blood type was relevant to severe disease risk for original variant.)
4. How to get access to new vaccines designed for Delta (or for “universal” Covid). Most likely route is clinical trials. Maybe some countries will approve earlier than others (e.g. UK, UAE).
5. Aside from being more infectious, is the guidance for avoiding infection from Delta any different? E.g. surfaces vs aerosol.
FWIW I’ve seen multiple double-mRNA-vaccinated people in my social circles who still got infected with delta (and in one case infected someone else who was double vaccinated). Two of the cases I know were symptomatic (but mild).
I also know of 5+ cases of symptomatic COVID among double-vaxxed people in the bay area (including one instance where most people in a group house of ~6 people got covid). These are also relatively healthy individuals in their 20s
I’d like to see investigations of the following:

Do you know which, if any, risk-reducing precautions they were following?
Some standard ones like masks, but not at all times. They probably were in close or indoor contact with infected people without precautions.
Immune response is generally associated with age and lifestyle. What can you tell us about those factors?
Age around 30 and not overweight or obviously unhealthy
How many asymptomatic? And how did people know of them?
