No. while the Moderna and Pfizer vaccines have proven to be effective in preventing COVID-19, there is a possibility that when you get vaccinated, you can be an asymptomatic spreader, meaning you can have the disease without knowing it. Early evidence from the Moderna vaccine shows promise that it can prevent the spread of the disease (more data is needed for the Pfizer vaccine). At this time, both the CDC and public health experts advise that even if you are vaccinated, masks should continue to be worn, practice social distancing, and wash your hands frequently.
