Poor service in Haverhill.

I support an elderly lady in Haverhill. She has not yet had a flu jab or covid booster as she is housebound. Having checked with her Gp surgery, she is on a list for flu but no info on when covid booster can be done. She has no mobile phone or internet so cannot get information easily.
There are hardly any walk in clinics for covid booster and if I book her an appointment, the closest is Cambridge or Newmarket!
