We’re relocating back to Ireland in February and, much as I love Trim, I’ll miss having Urangan pier in #HerveyBay as my morning walk
It was one of those rare Saturdays where I didn’t get called in to work, so we got to enjoy the local Osprey having breakfast
There are about 10 of these MASSIVE pelicans living on the pier. The locals call them all “Steve” because nobody can tell them apart 😂
Because I didn’t have to work, we were able to take a last-minute boat trip and watch the wildlife
Whales everywhere….
There’s the pier from the sky. All 850m of it. Surrounded by dolphins, turtles and if you have more modest tastes, whiting 😂 Once the borders open, I’d urge anyone who wants a big trip to head down under and visit Hervey Bay. One of the coolest places I’ve ever been

A short thread for parents, which will hopefully show why we can be confident that *nobody* is at risk of autism from the MMR vaccine. Below are some of the studies that look at the MMR and autism rates in different countries. Spoiler: The link does not exist…
….Firstly, the Lancet back in 2004, when all this was being debated, looked at people with autism and people who didn’t have autism, to see if there was any difference in their vaccination rates for MMR….
….These guys looked at both autism and the broader group of pervasive developmental disorders, of which autism is one type. They found absolutely no link between the MMR and autism or any similar conditions….
Interesting work on Hendra Virus in grey headed flying fox bats in Australia shows the presence of a new variant of Hendra (Hendra G2) in a sample of bats tested for Australian Bat Lyssavirus since 2013. For those not working in Oz, Hendra is a low-frequency high-consequence…
…infection that is responsible for the deaths of 5 people who became unwell after exposure to sick horses. The bats infect the horses, who then infect humans. Infection of horses seems to occur when they feed underneath bat colonies and are exposed to falling birth products or…
…urine and saliva, which contaminates their feed. The horses develop respiratory and/or neurological symptoms and often die. People who have close contact with them while they’re unwell can contract the disease. Up until a few years ago, we knew about one type of Hendra virus…
Incursion of European Bat Lyssavirus 1 (EBLV-1) in Serotine Bats in the United Kingdom - Interesting to see European Bat Lyssavirus (my third favourite bat lyssavirus 😂) establishing itself in another species of bat in the uk. EBLV is rabies’ brother… pubmed.ncbi.nlm.nih.gov/34696409/
…and is fatal in humans (though rare). It used to be pretty much only seen in Daubenton’s bat (which are also found in Ireland) but now seem to be establishing themselves in Serotine bats. Samples mostly taken in Southern England. Not sure if this species is seen in Ireland…
..as Serotine bats traditionally lived in continental Europe but seem to have adapted to southern UK. Surveillance is always going in in the background for low-incidence high-consequence diseases like these. Core public health work. #OneHealth
Mask-wearing cuts Covid incidence by 53%, says global study | Coronavirus | The Guardian This is all over my timeline today. I’m a fan of masks, and it is AMAZING progress to see a meta-analysis of public health interventions for covid. But….. theguardian.com/world/2021/nov…
..we need to look past headlines. This study looked at a range of measures, including masks, handwashing+disinfection. It’s well written and methodologically fine. But a meta-analysis can only analyse primary research and it’s conclusions are only as good as those studies….
…While people have been screaming at public health to “follow the science”, public health has been saying the science is blighted by confounders. So we need to be careful about interpreting the finding around masks, as the authors themselves point out. 6 studies. Big bias risk…
It’s been a real Rabies/Lyssavirus week for me. And whenever that happens, I’m always amazed how much of an absolute operator the virus is. Some of it’s basic abilities include - Fooling your body into reducing its immune response (considering these viruses are 100% fatal….
…that’s quite the evolutionary achievement). One of the ways it does this is by inhibiting your body’s ability to produce B-interferon, which is a vital part of our immune machinery. In fact the #rabies virus has a whole chunk of its genome dedicated to doing just that….
…Rabies/lyssavirus also heads straight for your brain, where it increases the concentration of nitric oxide by about 25 times. That leads to a LOT of CNS overexcitement and it decreases your ability to fight off cell death; bad news when that’s happening in your 🧠……
As an end-user of the frankly awful data in the covid public health space, the best contributions that the various scientific advocacy groups and individuals around the globe could make, in my opinion, would be proper rigorous *systematic* reviews, especially around efficacy….
…of various mitigation strategies (many of which seem to be over-sold to the public) and the actual prevalence of the now well-defined long covid in different age groups. Without certainty around these questions, it’s really difficult to conduct rigorous risk assessments….
…,which are really the key to proper health protection. Instead we just get noise, with the public believing the 99% of stuff on twitter that is pure fiction, even from people who seem very credible and post links to convincing-looking papers. Most of what I see here is wrong.
