An FDA panel has voted against recommending approval of a booster COVID-19 shot for the general population – disappointing some public health officials.
In the reluctance to vaccinate, there is a lack of trust and understanding of the scientific process. Better communication would help rebuild bridges.

Before the pandemic, the public perceived science as infallible and inaccessible. But the opening up of research to the general public has changed that perception.
Influenza virus particles.
Two different respiratory viruses were found to swap proteins when they infected the same cell.
The huge number of active coronavirus infections offers plenty of opportunity for mutations to occur and new variants to arise.

When the coronavirus copies itself, there is a chance its RNA will mutate. But new variants must jump from one host to another, and the more infections there are, the better chance this will happen.
The next months are going to remain difficult. But I’m still hopeful about the future. There will come a point when enough people are vaccinated that case numbers begin to decrease.
People getting vaccinated may still have questions about COVID-19 vaccines, like why it takes two doses — and then two weeks — to take full effect.

A medical student answers questions he gets asked at a COVID-19 vaccine clinic: Efficacy versus real-world effectiveness, immune response and how the mRNA vaccines compare to vaccines already in wide use.
By better communicating how vaccines boost the immune system’s long term “memory”, manufacturers could address vaccine hesitancy.
Cell-mediated immunity is particularly effective at eradicating viruses, and more durable. This is important in the fight against COVID-19.
It’s not spreading widely, and it’s not at Australia’s doorstep. The tools we have in place work against the coronavirus.
There are practical things you can do to make your child more comfortable if they’re ill.
COVID-19 vaccines have been proved safe and effective. But it’s understandable to have questions.

An infectious disease doctor explains the science behind COVID-19 vaccines at a level that children – and adults – of all ages can understand.
Vaccines against COVID-19 are the safest – and fastest – way to prevent the spread of variants.

A 2015 paper on chicken virus evolution is being taken out of context and used to fuel fears about COVID-19 vaccines. Its lead author aims to clarify the science in hopes of saving lives.
Children can get long COVID, but it seems to be less common than in adults. And they tend to recover quicker.
Australia plans to begin relaxing restrictions once 70% of over-16s are fully vaccinated. But as Israel shows us, it’s likely not enough to reach herd immunity, especially with the Delta variant.
Italians must now present a form of vaccine passport called a ‘Green Pass’ to enter many indoor establishments.

After enduring a devastating wave of infections, deaths and lockdowns at the start of the pandemic, Italy is putting in place tougher anti-COVID measures, including a vaccine passport.
Evolution explains why the Delta variant spreads faster than the original Wuhan strain. It explains what we might see with future variants. And it suggests how we might step up public health measures.
A$50 million could provide all NSW school classrooms with air purifiers with HEPA filters. This pales compared to the roughly $220 million-a-day cost of Sydney’s lockdown.
As troops enforce Sydney’s lockdown, two experts explain why using military rhetoric and personnel may undermine efforts to control the virus, especially among communities most vulnerable to COVID.
We found two small air cleaners in a single hospital room could clear 99% of potentially infectious COVID aerosols within 5.5 minutes.
COVID-19 vaccination in Africa is speeding up.

In Africa, it’s more rational to prioritise vaccine access, rapid rollout and community engagement, than pushing the narrative of vaccine-induced population immunity.
Many long COVID sufferers are reporting having ‘brain fog’, where they can’t concentrate as well as they used to.
