There's a nation-wide shortage of Twinrix, the vaccine used to prevent hepatitis A and B in adults, children and infants, according to Canada's mandatory drug shortage and discontinuation reporting website. Dual vaccine not always necessaryDr. Robert Birnbaum said people shouldn't worry about the shortage because for most travellers, the dual vaccine isn't necessary because hepatitis B is often sexually transmitted. He's more concerned with a concurrent yellow fever vaccine shortage because it is required to travel to certain parts of the world. Dr. Robert Birnbaum, who specializes in travel medicine, says people shouldn't panic about the Twinrix shortage because for most travellers, the dual vaccine isn't necessary. CBC attempted to clarify the reason for the current Twinrix shortage, but didn't receive a response before publication.
