we are london based and looking for a clinic that does the single measles jab? there seems to be 2 different strains, one from india and 1 from france. i believe the 1 from india is not cultivated in eggs and hence children that are allergic to eggs can have it. most of the clinics we have looked at, state that they are Quality Care Commissioned but when we go on the QCC website there don't seem to be there, which makes us a bit nervous about there practice. pls. share your experiences. thanks.
