While mRNA vaccines are designed to last longer in the body than mRNA molecules typically would, they are also tested to ensure they are eliminated from livestock long before milking or slaughter.
Involving young patients and their parents or caregivers can help bring new research evidence into clinics.

As people flock back to offices and pack public transport, we’re seeing more cases of the flu than in recent years. The flu shot isn’t perfect but it cuts your chance of being hospitalised.
The long-awaited vaccine is a necessary tool in the fight against the most common respiratory viruses.

Polio vaccines have been a massive public health victory in the US. But purely celebratory messaging overlooks the ongoing threat if vaccination rates fall.
One in three infants is not immunised against pertussis. For Māori babies, more than half are at risk from the potentially deadly infection. But there are relatively simple things we can do.
Inflammation of the heart (shown here), known as myocarditis, can be triggered by viral infection, including COVID-19, as well as from COVID-19 vaccination, in rare cases.

Parsing the risk of myocarditis from viral infection versus vaccination is challenging, and researchers are intensely studying the various factors that are at play.
Curbing vaccine hesitancy is as much a matter of acknowledging its social, historical, and cultural roots as it is of addressing its clinical dimensions.
The northern hemisphere has seen a surge in winter viruses.

A couple of theories are popular for explaining why we’re currently seeing very high levels of respiratory viruses, but they’re not based in science.
Many viruses interact with the olfactory system, and can damage other areas of the brain through it.

Inflammation and damage to the olfactory system from shingles, COVID-19 and herpes infections may contribute to Alzheimer’s disease.
A new study has looked at more than 15,000 people across 21 countries to assess whether vaccinated and unvaccinated people discriminate against each other.

Amphibians have been devastated by a chytrid fungus pandemic. Researchers immunized California red-legged frogs in Yosemite to give them a fighting chance at survival, with surprising results.
Nasal vaccines for COVID-19 are still in early development.
