A Study to Learn More About Prevenar 20 Once it is Out in the Korean Market

The purpose of this study is to understand the safety of Prevenar 20 (Pneumococcal 20-valent conjugate vaccine) once it is out in the Korean market. Prevenar 20 will be given to participants aged 6 weeks or older in Republic of Korea.

This study is seeking for participants who are:

* Infant, children and adolescents aged 6 weeks to under 18 years or adult who are 18 years or older
* Prescribed Prevenar 20 by their physician as per approved product label

All participants in this study will receive Prevenar 20 vaccine.

1 dose (0.5 mL) of Prevenar 20 will be given into a muscle, preferably to the shoulder muscle.

We will look at the experiences of people receiving the study medicine. This will help us see if the study medicine is safe.

Participants will take part in this study for 28 days. During this time, study doctor collects the data of subjects to understand the safety of study medicine. There is no strict fixed visit schedule. If subjects are unable to visit the study clinic 28 days after Prevenar 20 vaccine was given then the safety information will be collected by telephone or e-mail.

The study design will reflect the actual management of subjects in routine clinical practice. The study will be performed by continuous registration method. Investigators enroll subjects who receive Prevenar 20 (Pneumococcal 20-valent conjugate vaccine) for the first time after the start of the study.

Data can be collected at routine scheduled and/or unscheduled visits. There is no mandatory fixed visit schedule. Investigator collects the data of subjects from the time of the subject's first dose of study drug to a minimum of 28 days following administration of study drug, to evaluate the safety of study drug and records the information in each subject's Case Report Form.

As no additional visits or tests are required for this study, the data specified in this protocol may not be collected from all subjects.
