Sir: In my school in the 1930s no one had asthma. In my children's schools in the 60s and 70s, in a rural area, one in three or four had the disease.

The only thing not common to both groups was that we were not vaccinated as babies, whereas my children and their contemporaries had multi-vaccines at an early age. As asthma seems to be an allergic reaction I often wonder if the immune system is over-sensitised at too early an age. All sorts of other allergies seem much more prevalent.
