As detailed in the previous instalment, after a couple of days I considered myself the textbook case of a fully vaccinated individual that has caught COVID but has pretty mild symptoms. I was starting to wonder if this was going to be a one-entry COVID diary. However, by day four it got a bit more … Continue reading COVID Frontline: A breakthrough infection and a lockdown lifts
Vaccines are highly effective at preventing death from Delta A Scottish study of 100,000 Delta-positive people has found that the AstraZeneca and Pfizer vaccines are highly effective at preventing death: 91% and 90%, respectively. The research, which is published in the New England Journal of Medicine, examined data on vaccination status, COVID testing, and mortality … Continue reading COVID Booster: Pregnancy loss, steroid side effects, and climate change
Vaccines do have side effects, but there are some social-media users peddling myths that COVID-19 vaccines cause male infertility and sexual dysfunction. This is not the case – there is no established link between COVID vaccines and male fertility, though falling ill with COVID-19 may pose a risk of sexual dysfunction. Do vaccines cause infertility … Continue reading Do COVID vaccines affect male fertility?
With Christmas looming, many Australians are keen to see international borders reopen. But how do we know the right time to do so? Politicians have leaned on Doherty modelling to build a national plan for reopening international borders, but while mathematical models are powerful tools for predicting potential surges, their predictions are still hypothetical. They … Continue reading Opening Australia: It’s not a model problem
Some people get severely sick with COVID-19. Others don’t even notice they’ve caught the infection. The phenomenon intrigued scientists, who began to probe the human genome in search of clues that could help them understand why some people quickly succumb to the coronavirus and others are unaffected by it. Over the past months, several studies … Continue reading COVID’s genetic solution?
On 17 September, CNN published an online story with the heading: “Moderna’s vaccine is the most effective, but Pfizer and J&J also protect well, CDC-led study says.” That news suited me just fine – I received my first dose of the Moderna vaccine in January, and took the second shot in February. Two days earlier, … Continue reading COVID Frontline: What’s it like to get a Moderna booster?
TGA officially approves rapid antigen tests The Therapeutic Goods Administration has officially approved three rapid antigen self-tests for COVID-19. While they’re not as accurate as the gold-standard PCR testing, these tests deliver results in 20 minutes and can be done by a non-specialist. (Cosmos has an explainer on rapid antigen tests here.) They’ve previously been … Continue reading COVID Booster: Nasal vaccines, music and donation generosity
So on Tuesday I got a text: Your COVID test is POSITIVE. That’s how I became only the second person I know well who’s caught COVID; for an Australian, that’s probably not too unusual. But let’s roll back a bit. I live between Adelaide and Melbourne; my partner Nicola moved to Victoria to take up … Continue reading COVID Frontline: Getting COVID in a lockdown city
In February 2020, São Paulo had a major street carnival. I lived in the old downtown area, where the most interesting and absurd parades were held. Even for a person like myself who is not usually into parties, it was amazing to witness the biggest South American city in its most vibrant, happy, and celebratory … Continue reading COVID Frontline: Brazil
As New South Wales approaches the 80% double-dose target, restrictions will ease in the next few weeks, and most businesses are expected to reopen. Although the high vaccination rate is highly encouraging, increasing people’s movements and mingling might result in a surge of COVID-19 cases. The NSW Government has developed COVID Safety Plans for workplaces … Continue reading How can Australia safely return to work after COVID lockdowns?
Delta variant deadlier than original COVID strain Researchers have found that the Delta variant of COVID-19 is associated with higher risk of death, hospitalisation and ICU admission. Using data from 212,326 COVID-19 cases in the Canadian province of Ontario, the study found that Delta infections were 133% deadlier than infection with the original COVID strain. … Continue reading COVID Booster: Delta deadliness, Pfizer effectiveness and drinking habits
Pandemics are a great opportunity for fraudsters. With the desperation for new treatments, a tsunami of research crashes onto preprint servers or is hurried into publication, breaching the dam wall of careful peer review. Surfing that tsunami, fraudsters have seized the opportunity to make a name for themselves, particularly when it comes to publications that … Continue reading Data detectives dig into ivermectin studies
