I thought if you got an mRNA-based shot like Moderna or Pfizer, you should boost with the same type, JNJ isn’t. Is mixing and matching between the two still effective? (Question directed to anyone)

Edit: nm, you should. https://www.cnet.com/health/johnson-and-johnson-covid-booste...

Yes people that got jnj are advised in USA to boost with mRNA vax.
