Since no one is without a home country here on DR1...at least I hope they are not...
Everyone who may not be covered or who may be covered (but not within the time frame on the DRGOV schedule) can return to their home countries for VACVID-19
Just check the requirements to enter your home country and the availability of VACVID-19 first.
What if you have to be vaccinated to travel to your home country to get vaccinated?
