Among fully vaccinated people who never had COVID-19, getting a third dose
of an mRNA vaccine from Pfizer/BioNTech or Moderna would likely increase
levels of antibodies, but not antibodies that are better able to neutralize
new virus variants, Rockefeller University researchers reported on bioRxiv
ahead of peer review.
They note that in COVID-19 survivors, the immune system's antibodies evolve
during the first year, becoming more potent and better able to resist new
variants.
In 32 volunteers who never had COVID-19, they found that antibodies induced
by mRNA vaccines did evolve between the first and second shots. But five
months later, vaccine-induced antibodies were "equivalent" to those seen
after the second dose, with "little measurable improvement" in the
antibodies' ability to neutralize a broad variety of new variants, said
coauthor Michel Nussenzweig.
Therefore, he said, giving those individuals a third dose of the same
vaccine would likely result in higher levels of antibodies that remain less
effective against variants. |

反正mRNA的都完了，worst case scenario变现实了
不打boost，就等着ADE了，因为抗体效果差，浓度低。
boost唯一用途就是提高抗体浓度，防ADE，这个也有问号？
