The Novavax vaccine just got approved. It’s a traditional vaccine, and not mnra.
Noravax is a sub-unit vaccine, not as new tech as mRNA but still newish. For example, the new shingles vaccine is a sub-unit vaccine. It took ten years for it to be approved.
And, Noravax works by injecting spike protein directly to trigger an immune response rather than using your own cell machinery to produce it in your body.
In other words, Noravax still exposes you to the spike protein.
