It is more than just the SEALS. THis was posted on a Naval Base FB page:
UPDATE ON COVID-19 VACCINE REQUIREMENTS: NAVADMIN 225/21 dictates active duty Sailors must be fully vaccinated by Nov. 28, selected reservists by Dec. 28. Noncompliance will result in administrative separation, absent a pending or approved exemption.
Effective immediately, commands shall not allow Sailors refusing the vaccine to promote or advance, reenlist, or execute orders, with the exception of separation orders, until the COVID Consolidated Disposition Authority (CCDA) has completed disposition of their case.
The CCDA retains authority to remove warfare qualifications, additional qualification designations, Navy Enlisted Classifications, or sub-specialties. The CCDA may also seek recoupment of applicable bonuses, special and incentive pays, and the cost of training and education for service members refusing the vaccine.
Navy leaders refusing the vaccine will receive written notification that they have five days to begin a vaccination series or request exemption before being relieved.
