Even Sweden is still a long way off from herd immunity.
Paul Kelly on the second-wave of coronavirus
Michelle Grattan speaks with Deputy Chief Medical Officer Paul Kelly about the second-wave of coronavirus.
If the UK relaxes social distancing now, while most of the population is still susceptible, it runs the very real risk of a second wave.
One practical exit strategy from lockdown would be identifying green zones, and progressively joining them together once it is safe to do so.
Starting to feel a little more optimistic? Look away now.
Of the four broad options for coming out of lockdown, a controlled building of ‘herd immunity’ in the population may be our best hope of recovery from the pandemic if a vaccine is not found soon.
Could the 1889-1890 pandemic have been the result of cow coronaviruses jumping to humans?
It’s based on a combination of mathematical modelling, computer simulation and historical data from other pandemics.
Without a coronavirus vaccine, a herd immunity strategy would simply lead to thousands of unnecessary deaths.
Letting the virus ‘pass through the community’ is not a good public health strategy.
Large-scale adoption of simple, individual actions — like disinfecting our germ-laden phone screens — can limit the ability of COVID-19 to get a foothold.
From fear of needles to religious beliefs, there are all sorts of reasons why people choose not to vaccinate.
When a certain percentage of a population has been vaccinated, it prevents an infectious disease from spreading. But that threshold depends on the disease.
Measles cases in the US have reached their highest in 25 years. A bioethicist argues why parents opposed to vaccination are not just wrong about the science, but about the morals.
Recent measles outbreaks show the dangers of not vaccinating – and the importance of vaccination. Is there a way to accommodate those religiously opposed to vaccination and minimize other exemptions?
Billboards spreading misinformation on the risks of vaccination have popped up around American cities. A bioethicist explains why decisions not to vaccinate children are indefensible.
Your risk of a heart attack increases 600 per cent within a week of catching the flu. The flu shot decreases that risk, whether you catch the flu or not.
Stating a majority of people won’t benefit from a vaccine ignores the purpose of immunisation programs.
The flu vaccine isn’t perfect but it’s the best way to protect against these potentially harmful viruses. Most children aged six months to five years are eligible for a free vaccine in 2018.
