More evidence that multiple vaccines do not weaken the immune system

A new study from the US provides further evidence that it is safe for babies and children to receive several vaccines in one go. Vaccines such as the 6-in-1, which is given in 3 doses to babies in the UK, are combination vaccines, protecting against several different diseases. Some parents have been concerned that multiple vaccines in early childhood could weaken their child's immune system.

In this new study the researchers compared two groups of children aged from 2 to 4 years. In one group, all the children had visited A&E or been hospitalised with an infection that cannot be vaccinated against (for example, many types of chest infection and stomach upsets). In the control group, none of the children had visited hospital with this sort of infection.

The researchers then looked at how many vaccines the children in each group had received in the first two years of life, and found that there was no significant difference between the two groups. (If vaccines did weaken the immune system, you would expect to find that the children hospitalised with infections had received more vaccines that the ones who were not hospitalised.)

Earlier studies have already found no evidence that childhood vaccination is linked to an increased risk of developing type 1 diabetes or conditions such as multiple sclerosis .
