Researchers rushed the development of the COVID-19 vaccine, so its effectiveness and safety cannot be trusted.

According to studies, the two first immunizations are both roughly 95% effective — with no major or life-threatening adverse effects. There are several reasons why COVID-19 vaccines might be created so fast. Here are a few examples:

• Pfizer/BioNTech and Moderna developed the COVID-19 vaccines using a technology that had been under development for years, allowing the firms to begin the vaccine development process early in the pandemic.
• China quickly identified and provided genetic information regarding COVID-19, allowing scientists to begin developing vaccines.
• The vaccine developers did not omit any testing phases, but instead performed several of them on an overlapping schedule in order to collect data quicker.
• Governments invested in vaccine development and/or paid for vaccinations in advance, thus vaccine initiatives had lots of money.
• Some COVID-19 vaccines were generated utilizing messenger RNA (mRNA), which provides for a speedier approach than the standard vaccine manufacturing method.
• Companies used social media to identify and engage study volunteers, and many were eager to participate with COVID-19 vaccine research.
• Because COVID-19 is so contagious and prevalent, it didn't take long to see if the vaccine worked for the vaccinated trial subjects.
• Companies began producing vaccines early in the process, even before FDA approval, so some supplies were ready when FDA approval was granted.
