Honestly the Russian vaccine and possibly the astrazeneca Vaccine appears to be the safest bet. No mRNA just the old school modified cold virus delivery mechanism. Method been done for years .. easier and cheaper to manufacture and distribute. Call me a cynic but I think the US (and UK) will push through a somewhat experimental version by Pfizer because “money”. Hope I am wrong. But I would imagine in a year or so we will “discover” that the cheaper vaccine works great (after giving Pfizer plenty of time for $$)

Aren’t there issues with adenovirus vectors?

  Yes but these are known variables. Hypothetically the newer mrna vaccines should be safe .... but there honestly is no long term information. A MRna vaccine has never been approved for human use until now.

    I believe the same is true for adenovirus vector vaccines: none have previously been approved for human use. [1] That said, both mRNA vaccines and adenovirus vector vaccines have a history of clinical trials stretching back at least a decade. [1] [2] So in addition to there being no major long-term risk in theory, we do have some real world experience with both types of vaccines in tests.
