This article as well as many others confuses meaning of "infection" and "disease". This is a very important distinction. The Pfizer press release says it is 90% effective at preventing the disease [1], it does not say the vaccine prevents infection.

COVID-19 = the name for the disease cased by the virus

SARS-CoV-2 = the name of the strain of coronavirus that causes the COVID-19 disease.

This vaccine is 90% effective at preventing the disease, but while infected, you have replicating RNA in your body and will be contagious.
