the vaccines you need before going abroad

The end of the year is a period when Thai people commonly travel abroad, whether to Asian regions such as Japan, Hong Kong, Singapore, as well as Europe, or to explore nature and wildlife in Africa. When planning to travel abroad, besides preparing plans regarding the destination, activities, clothing, and equipment suitable for the country&#8217;s weather, another important aspect not to be overlooked is “protecting oneself from illness during travel,” which includes preparing regular medications as well as vaccinations to prevent diseases.
<h2>Vaccines… an immune booster for travelers 
</h2>
If you are wondering which vaccines you need before traveling… you need to understand this part. Currently, vaccines for travelers are divided into two categories: “required vaccines” and “recommended vaccines based on suitability.” It is advisable to get vaccinated at least 6-8 weeks before traveling to ensure comprehensive disease protection before departure.
<ol>
<li>Required vaccines before travel (Required vaccine) are vaccines that travelers must receive before traveling, according to international health regulations (WHO IHR). Currently, there is only one required vaccine: the yellow fever vaccine. Travelers going to areas with yellow fever outbreaks, such as countries in Africa and South America, must receive this vaccine at least 10 days before traveling.</li>
<li>Recommended vaccines for travelers based on suitability (Recommended vaccine for travelers)<span style="background-color: rgb(255 255 255 / var(--tw-bg-opacity)); color: var(--tw-prose-body); font-family: ui-sans-serif, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, 'Noto Sans', sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'; font-size: 1rem;"> These vaccines are recommended for certain travelers or groups based on suitability. Doctors will consider various factors such as the risk level of infection in the destination country or area, the duration of stay, activities planned (e.g., work, study, or tourism), as well as the traveler’s health and the disease itself.</li>
</ol>

Because modern fast travel allows infectious diseases or epidemics to spread rapidly across continents, vaccination to prepare the body helps prevent and reduce the severity of diseases. Travel confidently with your family next time. Don’t forget to check your own and your travel companions’ vaccination status to ensure you have received the appropriate vaccines as recommended by doctors, as well as undergo a health check before traveling, so your trip will be smooth and enjoyable without interruptions.

Every trip, planning is important. Besides preparing plans about the places to visit, activities to do, clothes, and equipment suitable for the weather of that country, another important thing not to be overlooked is "protecting yourself from getting sick while traveling."
