The main observations that they have ever had an vaccination against smallpox or not and how they are:
1. If a person over 48 years old who was born before 1974 has a high chance of having had a smallpox vaccination. Because Thailand is a country that has mobilized a lot of vaccination during that period. Therefore, smallpox is eliminated from Thailand. Most of them are injected at school.
2. If under 42 years of age, born after 1980, it is considered to have never received a smallpox vaccination before.
3. In the case of people aged 43-47 years, born before 1980 but born after 1974, it is a crossover period. will have to continue to examine the scar
4. To check the scar Most of which are injected in the left upper arm.
In the case of vaccination against smallpox The scar is a flat or slightly pitted wound. But if it is an anti-tuberculosis vaccination called BCG, the scar will bulge.
