Introduction to Travel Vaccination

This article is to help enlighten those people who are planning to travel remote locations and who want to know about various travel vaccines and their effects. In the below segments of this write up, we will understand how travel vaccinations works.
The word vaccination comes from the Latin word “Vacca” meaning cow and was invented by Edward Jenner in 1796.
Travellers always need travel vaccination to tour abroad and use the recommendation of these vaccines depend upon the following factors:
  • Country you are visiting, or which part of the same country you are visiting
  • The season and the time of travelling for example rainy season, winters etc.
  • In which area you are staying like rural area, developed area or urban area
  • What traveller will be doing during visit such as working or visiting in urban or rural areas
  • How long the traveller will be staying
  • The age of the traveller
  • The health of the traveller and so on
Plan Ahead:
Get expert advice about your travel immunization at least one month before you are due to travel.
How do travel vaccines work:
Vaccinations provide two type of immunity:
  • Active Immunity
  • Passive Immunity
Active Immunity:
Vaccine offer active immunity where human body is stimulated to create its own antibodies. Such kind of vaccines stimulate the body’s immune system to make defence antibodies, which stay in the body for a long period of time. Whereas the chemicals (antibodies) to a particular disease are present in the body, the body is protected from that kind of disease or infection.
The protection offered by such kind of travel vaccinations naturally takes some time, but their effect lasts a long time. Following are the name of some vaccines that work on the same principal of vaccination:
  • Live attenuated vaccine
  • Inactivated vaccine
  • Detoxified exotoxins
Passive immunity:
On the other hand, passive vaccines offer immediate protection. Passive immunity includes insertion in the body antibodies that have already been created rather stimulating the body into creating antibodies to an infection.
In this way, it is advantageous that the chemicals (antibodies) can go to perform actions defending the body straight away. It had also the disadvantage that the time of protection it offers is usually quite short as compared to active immunity.
For example: Hepatitis A immunoglobulin vaccine is an example of passive immunity which acts immediately but cannot work longer than three months.
The diseases for which variety of vaccinations are available are all hazardous and carry severe risks. So,it is necessary to have vaccination before travelling any remote location so to remove health risks.
