Pfizer Slow-Plays Results Of COVID Vax Trial In Pregnant Women

  • When covid-19 vaccines were granted emergency authorization in Dec 2020, there was consternation over whether pregnant women should be vaccinated.
  • In the absence of any human data, Pfizer announced it would begin recruiting volunteers for a clinical trial to examine the safety and efficacy of its mRNA vaccine in pregnant women and their newborns.
  • The trial, which began in February 2021, originally intended to enroll 4,000 women, but enrollment stopped in late 2021 with just 349 participants.
