Why are there now separate vaccines for under 65 and 65 and over? I havn't heard a satisfactory answer to this. There is a vague statement on the NHS website saying that the adjuvanted trivalent vaccine "has been shown to be more effective in this age group" than the quadrivalent vaccine, but I would like to see the statistical analysis for this. Some pharmacies seem to have got only one type in, not realising that there are two and are turning the other type of people away. And our doctor's receptionist, thinking that there were vaccines for over 65 and under 65, told me that there wasn't one for me as I was 65 exactly.
