What if there is no SMS notification on the day of vaccination?

The child is almost two years old, and there is generally no SMS notification. Generally, I calculate the time myself, one month in the early stage and longer in the later stage. Every time you finish the vaccination, you can ask the people at the epidemic prevention station when the next vaccination will be given. Generally, it doesn't matter if it is staggered for a few days. Sometimes, if the child is sick and has skin problems or something, it must be staggered. If the local epidemic prevention station does not have the vaccine you want to vaccinate, you should call the epidemic prevention station in advance to ask if there is one, and then go to vaccinate. Generally speaking, if you know the time of the next vaccination, you can set a time stamp on the mobile phone calendar, and you will be reminded in advance when it is time.
