Covid/flu jabs

My GP surgery has sent out their first invites for this winter's flu and covid jabs.

I have not replied -- for me end of August is much too early toahve the flu jab (themain one I am really do want to have). I thought these usually had a limited life (about three months). So, usually get this end of October/November hopefully to see me through the bad winter months.

Anyone else being offered these so early???
