Dr. Fauci, the highest paid employee of the Federal Govt, now suggests wearing 2 masks, even if you got the experimental emergency use mRNA vaccine.
He may mean especially if you got the experimental mRNA vaccine, because Dr. Fauci knows about Antibody-dependent Enhancement (ADE) and that it is a potential concern and risk factor.
If you got the experimental mRNA vaccine, you should know about it too, and probably take his advice on the masks.
"In general, virus-specific antibodies are considered antiviral and play an important role in the control of virus infections in a number of ways. However, in some instances, the presence of specific antibodies can be beneficial to the virus. This activity is known as antibody-dependent enhancement (ADE) of virus infection. The ADE of virus infection is a phenomenon in which virus-specific antibodies enhance the entry of virus, and in some cases the replication of virus."

"The simple definition of ADE is “raising antibodies that don’t protect, but actually make a viral infection even worse”. And obviously, that’s the opposite of what you want."
"At this point, I would say that the main worry for any ADE effects would be if the coronavirus mutates to the point that the antibodies generated by the current vaccines become non-neutralizing. And honestly, I don’t see that happening (it certainly doesn’t seem to have happened yet)."

Yet.
