Yes, exemptions to the booster requirement are available here for those who completed their initial COVID-19 vaccine series. If you previously completed an exemption request and were approved for the initial COVID-19 vaccine series, you need not apply for an exemption to the booster requirement. Individuals who still have not completed their primary vaccine series and would like an exemption from the vaccination series should submit an exemption request through Vax Viewer. 

If you are out of the country and do not have access to get the booster, you should submit a request for a booster postponement, also available in Vax Viewer.
