I had a course of three Hep B jabs in Apr/May/ October 2019. Vax was Engerix-B (Adult dose).
In August 2021 general health blood tests revealed no Hep B infection, past or present. Most worrying it went on say "no evidence of immunity to HepB"
According to hepb.org I am a non-responder so should start another course with a different vaccine. In Aug/Sept I had the first two jabs of HB-VAX 11 (Adult). The third dose is due April 2022. This vax has a short shelf life, must be kept refrigerated, not frozen, so you can't take it with you.
Can I get this brand in Thailand? I can wait a few extra weeks I suppose but after two years away stuck in Melbourne I really need a break.
