Awesome getting the vaccine so quickly. I'll be curious to see if health officials on St. Martin will relax or waive testing requirements given the fact that you'll be fully vaccinated by 1/29. By receiving the second injection on 1/8, you should have sufficient antibodies built up in your system within two weeks after that date to prevent significant infection from contact with the virus. However, mask wearing and some degree of social distancing will likely be necessary for a while until it is determined that vaccinated individuals cannot spread COVID. With your wife in education (like my wife) you may want to check into her getting the vaccine sooner based on whatever guidelines you have in Michigan, because I believe those in education with contact with students, faculty, staff, etc. would be Phase 1B under CDC guidelines. Maybe she can get the vaccine in January.
