But, in answer to Coffeebean's question, yes I would get the J&J version if that's all that would be available. And the congressman in the link above may remain free of symptoms but could pass on the virus.

We have to keep in mind that we do not achieve the promised immunity after both shots of either the Moderna or Pfizer vaccine for a period of time. Immunity reaches a peak level two weeks after the second dose. The congressman who contracted Covid after the second shot may have contracted the virus during the time frame that he was not completely immune. Then there is the fact that neither vaccine is 100% effective in preventing infection. The 100% efficacy is for not having severe symptoms from the infection and not needing hospitalization.
