MYTH: The vaccines were rushed, so they are not safe.

MYTHBUSTER FACT

*Studies found that the two initial vaccines are both about 95% effective — and reported no serious or life-threatening side effects. Here are a few of the many reasons the COVID-19 vaccines could be developed safely so quickly:

  • The COVID-19 vaccines from Pfizer/BioNTech and Moderna were created with a method that has been in development for years, so the companies could start the vaccine development process early in the pandemic.
  • The vaccine developers didn’t skip any testing steps but conducted some of the steps on an overlapping schedule to gather data faster.
  • Vaccine projects had plenty of resources, as governments invested in research and/or paid for vaccines in advance.
  • Some types of COVID-19 vaccines were created using messenger RNA (mRNA), which allows a faster approach than the traditional way that vaccines are made.
  • Because COVID-19 is so contagious and widespread, it did not take long to see if the vaccine worked for the study volunteers who were vaccinated.
