==mRNA vaccine==
* The vaccine currently being developed and studied by Pfizer is an RNA vaccine that targets the spike protein, the spiky protrusion on the SARS-CoV-2 virus that allows the virus to attach to and invade human cells, initiating infection. 
* An RNA vaccine basically consists of an mRNA strand artificially created that codes for a disease-specific antigen which when injected in to the human or animal body, creates an antibody response.
* In fact, all of the vaccines being developed by major manufacturers working with Operation Warp Speed, the U.S. government effort to fast-track vaccines, target the spike protein. 

==Preliminary analysis==
The preliminary analysis evaluated 94 confirmed cases of COVID-19 in trial participants. 
The study enrolled 43,538 participants, with 42% having diverse backgrounds, and no serious safety concerns have been observed; 
Safety and additional efficacy data continue to be collected.
