Vaccines protect people from diseases, but don’t always prevent disease transmission; research ongoing to determine if COVID-19 vaccines stop transmission

According to the CDC and the FDA, a vaccine is a product that stimulates a person’s immune system to build defenses against a particular disease-causing microorganism, thereby preventing disease in the vaccinated individual. It is still unknown whether the COVID-19 vaccines developed by Pfizer-BioNTech and Moderna, which were approved for emergency use by the FDA, can stop transmission of the virus. Research is ongoing to address this question. Since it is currently unclear whether or not vaccinated people can still transmit the virus that causes COVID-19 to others, it remains important for people to follow preventative measures, such as washing hands frequently, wearing a face mask and practicing physical distancing.
