That sounds promising. Also, this article from September 2020 suggests that science existed to avoid the problem with ADE [Antibody Dependent Enhancement] which they already knew about by then, but did not make it clear whether all the vaccine manufacturers were trying to use it: .

The ADE risk commonly cited in the 2012 paper was specific to the nucleocapsid protein (N protein). With the N protein showing highest ADE potential and the S protein being critical to cellular entry via ACE2 binding, the S protein became the go-to target for nearly all the vaccine candidates at the beginning of the pandemic.

So yes, ADE was absolutely taken into account with these vaccines. If anyone is worried about antibody dependent enhancement, there is far less risk of that with the vaccines (which only expose your immune system to the S protein) than there is with getting a COVID-19 infection (which exposes your body to ALL the viral proteins).
