Take Heart - Quest for the Holy Grail RHD Vaccine

Quest for the Holy Grail RHD Vaccine The so-called Holy Grail of RHD prevention – a Group A Strep vaccine. But this dream is proving difficult to realise. “It’s clearly a disease which is associated with social deprivation. I don’t think anybody denies that that is the most significant factor relating to the condition. If a vaccine were shown to be effective, it would be the holy grail for finally eradicating this condition in Australia and New Zealand.” Professor John Frazer “Rheumatic fever and rheumatic heart disease were very common around the world. Those rates have dropped away significantly. The question you have to ask is, “Why have they dropped away significantly?” A lot of that is around the better delivery of health services, removal of the social deprivation factor in those countries that now never see a case of rheumatic heart disease. The likes of the US and the UK, for instance, you can talk to a GP, and they’ve never seen one in their entire career. Whereas, fifty years ago, it was fairly common.” Professor John Frazer In the twentieth century, all of Europe people had rheumatic heart disease. “We know what causes rheumatic fever, is it’s a Group A streptococcus. If we can eliminate Group A streptococcus, there would be no rheumatic fever, but how we get there we haven’t yet answered.” Associate Professor Nigel Wilson “One of the things that makes Streptococcus very difficult to make a vaccine against is that there are hundreds of different strains of Streptococcus,” explains Professor Michael Good. “So the individual can be exposed to one strain and they’ll develop immunity to that strain but then is totally susceptible to another strain they might encounter the following week or month. Therefore because there are so many different strains, it takes a long while to develop immunity to all of them.” Professor Michael Good. “People have been trying to make a vaccine for streptococcus for a long while. There’s been a lot of progress in recent years, and our laboratory has been testing a novel approach to a streptococcus vaccine, which we’re putting into a human trial.” Professor Michael Good. “If the vaccine proves not only to be effective, but also safe, then of course a vaccine which is primarily designed for adolescents and children then has to go through another clinical trial which focuses on whether it develops the right sort of immunity in adolescents and children, and of course is safe.” Professor John Frazer “I’m very confident that a vaccine will be created, because we know more and more now about the biology of the organism and how it avoids natural immunity, than we ever did before. Australia and New Zealand are working very closely together on the vaccine. Our indigenous populations in both countries suffer a very high rate of streptococcus pathology, and the governments in Australia and New Zealand are committed to developing this vaccine.” Professor Michael Good. As a result, the passage of a safe RHD vaccine to market, is likely to be many years away yet. If a child you know has: Sore throat Infected skin sores Sore joints OR Fever Don’t delay.
