Just got my first dose today, of the Moderna flavor, going back in 4 weeks for a second dose. The Pfizer is a 21 day time period between doses, while the J&J is single dose, but is less effective at producing useful antibodies as the Pfizer or Moderna, (85% vs 95% [after two doses]).
The differences are;

The differences are;
The COVID-19 vaccine from Johnson & Johnson uses existing technology that involves a virus called adenovirus, a common cause of respiratory infections. The DNA in the adenovirus is modified so that it produces a key part of the SARS-CoV-2 virus particle to which the body then develops an immune response. The adenovirus that delivers the SARS-CoV-2 DNA particle cannot multiply, so it does not cause infection. Because this system is based on stable DNA molecules, it does not require ultracold storage, making it easier to distribute.
The Pfizer and Moderna COVID-19 vaccine technology uses genetic material (mRNA) that code for parts of the SARS-CoV-2 virus protein. This mRNA is protected by lipid nanoparticles (fat bubbles) that, when injected, cause a person’s own cells to make pieces of viral particles to which the body develops immunity. Because the genetic material is broken down quickly, it stays in a person’s cells for only a short period of time. For this reason, these vaccines must be kept in very cold environments until they are ready to be given.
