    leaded solder without an extractor fan

    lead does not vaporize at the temps used in soldering.
    lead free solder also needs fume extraction. even more so actually, because it is used at slightly higher temps. even with perfect fume extraction, leaded solder can still poison you, because you touch it and then touch your face without washing your hands.
    if you are prone to allergic reactions from solder fumes avoid solder with a rosin core, use synthetic flux instead.

    If you mean an Immune escape that is not a real problem for rabies because that virus has a slow evolution as you can tell from the fact that the same vaccines that were used in the 80s are still used today. Compare that for example to flu or Covid-19 vaccines where even two year old vaccine types are considered outdated and not used anymore.
