After I receive both doses of the vaccine, am I still required to wear a mask at work?  

Yes.  We continue to follow CDC guidance on this subject.

The vaccines preliminary data shows it is 60-95% effective so there is a subset of the population that will not gain immunity from the vaccine.  Furthermore, the protective effect of the vaccine may take at least one month.  While experts learn more about the protection that COVID-19 vaccines provide under real-life conditions, it will be important for everyone to continue using all the tools available to us to help stop this pandemic, like covering your mouth and nose with a mask, washing hands often, and staying at least 6 feet away from others.

Unfortunately, the vaccine is not the proverbial “light switch” to turn off the COVID-19 pandemic.  It will take some time.
