A couple other items I'd like to share:

Thanks for stepping up and volunteering for the COVID-19 vaccinations and your continued COVID-19 mitigations at work and at home. The XO has been working very hard to provide EVERYONE with an opportunity to be vaccinated! I encourage everyone to get vaccinated unless your doctor advises otherwise. Please consider that by deferring the vaccine without a valid medical reason (determined by your doctor) you are making a conscious decision to become part of a chain, an enabler who will eventually spread the virus and potentially harm/hospitalize someone who doesn't have a choice. Time is not on your side. This is the chance to protect yourself, your shipmates and family...to break the chain. If you are in doubt please invest the time, seek one-on-one advice from your own medical professional.

Sounds like he might get a bonus if his command makes it to 100%.
