Was the SARS vaccine virus not mRNA?

• apexalpha 6y ago
  Yes, this is why these mRNA vaccines are here so fast; a lot of prework was done for SARS vaccine, which is also a Corona disease. But I think SARS died out before the vaccine was ready/needed.

    the parent is concerned regarding the appearance of ADE (Antibody-dependent enhancement) during the creation of the SARS vaccine. While we cannot totally disregard ADE, I assume we should have seen it by now (and the Oxford trial was stopped exactly because they thought they might have observed something like it). Whether it appears again on a population scale level, nobody knows.

      Yeah, I've thought about it too, but both mild reinfections and vaccine trials show that SARS-2 does not exhibit ADE.

      I don't know anything, but I've read that ADE can take 1-3 years to surface.
