Outstanding and similar ( so far) for protection.

Bit we need to see:

1. a better breakdown of performance in different age and ethnic groups groups

2. Amy major difference in short term side effects

3. how long protection lasts

4. whether it prevents virus from actually infecting

5. Long term side effects of RNA vaccines In general

6. how they compare to protein vaccines and vectored DNA vaccines

7. AND as noted the impact of production, transport, storage, shelf lives on long term use. and costs.

Lots to learn but ( especially given their designation as EUA) there Is still much to learn. However, they will certainly move us towards herd immunity and a more open economy.
