Thailand’s vaccination calendar may differ slightly from your home country or other countries you may be familiar with. This is important to keep in mind as the quest for a COVID-19 vaccine during the pandemic has highlighted the significance of immunization, especially during early childhood.
To ensure your child receives timely vaccines and boosters, it’s crucial to familiarize yourself with the mandatory vaccination schedule for children in Thailand.

Different countries vary in terms of which vaccines are required for young children. For example, the vaccine for tuberculosis (TB), known as BCG (Bacillus Calmette and Guerin), is not widely used in the USA, while it is a mandatory vaccine in Thailand. Also, most Asian countries, including Thailand, make vaccination against Japanese Encephalitis (a viral disease carried by mosquitoes) obligatory, while it is not required in most Western countries.
Besides these mandatory vaccines, pediatricians often recommend additional vaccine protection like Rotavirus Vaccine (contagious disease that can cause severe diarrhea and vomiting) or Varicella Vaccine (known as Chicken Pox), depending on the circumstances of each child. These include factors such as medical condition, lifestyle and travel plans. For this reason, parents should always consult their doctors before planning a course of vaccinations. This is especially important for expat families that need to move regularly for work assignments, as requirements vary from one country to another (different vaccines, doses, timeframe). If in doubt, they should seek a second medical opinion.
Since a course of vaccinations can be costly, parents can enquire about vaccination packages at their preferred hospital and see to include vaccination coverage in their health insurance policy.
