I have had a rather busy day even though I have had a day off. It has been time for me to review my vaccines. Vaccines are very interesting and previously I have worked scientifically two years with immunology. A vaccine is a biological preparation that improves immunity to a particular disease. It contains an agent that resembles the particular disease-causing microorganism, and is often made from weakened or killed forms of the microbe. In brief, the microbe stimulates the body’s immune system and a memory is induced. Later, the immune system can more easily recognize and destroy any of these microorganisms that it may encounter in the body. Complex chemical cascades in the body are induced with eg various immunoglobines (antibodies).

After some time, often years, the immunological memory is decreased and a new dosage of the vaccine needs to be repeated. I had three different vaccines today, so called booster dosages. Hepatitis A, tetanus and also against cholera. Normally, you are fine after vaccination, but there might be a few side effects. However, I did my exercise this evening since I feel ok.

“Tjejmilen” is approaching and I will spend time on my vacation running. Last summer I ran 8 km every day. I know I should do more interval training, and I will do that when possible. Exercise is definitely good for the immune system. No doubt about it.
