What if you haven't notified the booster for six months?

If you have been vaccinated with COVID-19 vaccine booster, you will not receive this message.

I received the news because the third booster vaccine has been given for six months after the second dose, so the government department will send text messages to those who have not been given the vaccine due.

But if you have been vaccinated, big data comparison will show that you have been vaccinated, so you won't send a text message to remind you.
