Carlton. Those with non-Japanese names like mine who are waiting to reserve for a 3rd booster shot for Covid-19, here is what you should be getting in your mailbox depending upon your vaccination status and eligibility. Kumamoto is going with the “first jabbed, first boostered” rule it would appear so if it hasn’t been 6-7 months since your 2nd shot you will need to wait for that date before you can expect a mail out. Not surprisingly this is an A4 size packet chock full of very detailed information.
