Vaccination intervals, routine/optional vaccinations, etc., change every year, and routine HPV vaccination resumed in April 2022.

Since textbooks from a few years ago may not be up to date,

① Vaccination timing and number of doses
② Vaccination intervals
③ Vaccination methods
④ Types of vaccines (live vaccines, inactivated vaccines, mRNA vaccines)
④ Details on MR, combination vaccines, BCG, etc.

<⚠️Points to note>

If you are administering an injectable live vaccine after an injectable live vaccine, you must wait at least 27 days. There are no restrictions for other types of vaccines.

The point to note is the case of "injectablelive vaccine to injectablelive vaccine."

In other words, there are no restrictions when going from an oral live vaccine to an injectable vaccine. (The same applies to the reverse case.)

You need to have a solid understanding of these definitions📖

Also, after immunoglobulin administration or immunoglobulin therapy (high-dose), the vaccination interval differs depending on the vaccine.

After immunoglobulin administration, live vaccines (measles, rubella, varicella, mumps) can be given after 3 months, and other vaccines can be given at any time.

As a point of caution, rotavirus and BCG are also live vaccines, but they are less affected, so there are no restrictions.


After immunoglobulin therapy (high-dose), live vaccines (measles, rubella, varicella, mumps) can be given after 6 months, and other vaccines can be given at any time.


Speaking of immunoglobulin therapy, Kawasaki disease comes to mind. You may be asked about vaccination timing in questions such as 'Which of the following is correct regarding guidance?'

Assume that vaccinations will definitely appear on the exam and make sure to grasp the key points✨
