Does anyone know the weight of 1 mRNA unit?

Asking because Pfizer seems to contain 50mcg of mRNA while Novavaxx conatins 5mcg of the actual spike protein...

Sorry pfizer is 30mcg, while moderna is 100mcg of mRNA.

Novavaxx: 5mcg Spike Protein
Pfizer: 30mcg mRNA --> ???mcg Spike Protein
Moderna: 100mcg mRNA --> ???mcg Spike Protein

It appears, based on the below, that 30mcg of Pfizer mRNA produce about 4,000mcg of Spike protein:

If that is accurate, we can say:

- Novavaxx: 5mcg Spike Protein
- Pfizer: 30mcg mRNA --> 4,000mcg Spike Protein
- Moderna: 100mcg mRNA --> 13,333mcg Spike Protein

So that would mean that the amount of spike protein your body would see is in relation to Moderna:

- Moderna: 100%
- Pfizer: 30% (3.3x less than Moderna)
- Novavaxx: 0.0375% (2,667x less than Moderna)

Important, since I think the Spike protein might be related to side effects.
