COVID-19 antibody study shows downside of not receiving second shot

A recent Northwestern University study reveals that receiving a second dose of the Pfizer or Moderna vaccine significantly boosts immunity against COVID-19. The research found that even prior exposure to SARS-CoV-2 does not guarantee high antibody levels or robust response to the first vaccine dose, contradicting common assumptions.
