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