Cysylltiadau aelwydydd a ystyrir yn flaenoriaeth fyddai'r rhai dros 16 oed sy'n rhannu llety byw gydag oedolion imiwnataliedig. Ar hyn o bryd, nid yw'r JCVI yn cynghori brechu cysylltiadau cartref plant imiwnataliedig, na phlant sy'n gysylltiadau cartref ag oedolion imiwnataliedig.
Household contacts considered as a priority would be those over 16 who share living accommodation with adults who are immunosuppressed. The JCVI does not currently advise vaccination of household contacts of immunosuppressed children, or children who are household contacts of immunosuppressed adults.
