All currently available COVID vaccines in the United States help protect against COVID-19.
All available vaccines are highly effective, particularly against severe disease leading to hospitalization and potentially death.
As per Dr. Fauci, do not discriminate against any of the available vaccines. “I would recommend getting the first one you can get.” The best vaccine to get is whichever vaccine is available to you at the time of your appointment. The earlier an individual is vaccinated the earlier their protection starts to work.
You can’t directly compare the 3 available vaccines because the trials were done differently and during different times in the current pandemic.
