The main observations that they have ever had an vaccination against smallpox or not, as follows:
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 been inoculated against smallpox before.
3. In the case of people aged 43-47 years, born before 1980 but born after 1974, it is a crossover period. Will need to continue to check 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. In the case of an antituberculous vaccination called BCG, the scar will bulge.
Therefore, it is important to check whether you have ever had smallpox/smallpox vaccination. It uses two principles as mentioned. See if it was born before 1974 and check how the scars have formed. A wound that is smooth or slightly pitted It is considered to have been inoculated against human smallpox or smallpox.
