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.
Catch-up vaccinations are free. These hints and tips will help you get started.
Intent to vaccinate cannot be used to predict uptake.

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.
California red-legged frogs are threatened with extinction.
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.

An effective nasal vaccine could stop the virus that causes COVID-19 right at its point of entry. But devising one that works has been a challenge for researchers.
Early treatment with antibiotics can be life-saving.
Paradoxically, despite the success of COVID vaccination campaigns, confidence in vaccines has dropped significantly since the onset of the pandemic.
The first malaria vaccine, Mosquirix, was approved by the WHO in 2021.

For a malaria vaccine to have an impact, health promotion is key. Awareness campaigns must address safety concerns and emphasise expected positive impacts.
The pandemic and a health workers’ strike disrupted essential health services.

Outpatient visits, screening and diagnostic services, and child immunisation were particularly negatively affected.
An immunologist looks at the evidence.
Since immunity from COVID vaccination begins to wane over time, it’s important that everyone, irrespective of age, receives their boosters as soon as they are eligible to do so.

A major lesson from the COVID-19 pandemic is the need to decolonize transnational governance so that the world is better able to handle both future and current global crises.

Countries have to weigh up the cost of vaccinating everybody versus the cost of treating the disease.
The current outbreak in non-endemic countries is being spread entirely from human to human.

The right public health measures can be very effective at curbing the virus’s spread – if executed properly.
The risk of serious disease outbreaks among NZ children is now very real. Some childhood immunisation rates have dropped from about 80% in early 2020 to 67% by June 2022, and as low as 45% for Māori.
The Jynneos monkeypox vaccine provides strong protection against infection but is in short supply.

There are two approved monkeypox vaccines in the US. Both use a related poxvirus called vaccinia to produce an immune response that protects against smallpox and monkeypox.
A health-care provider administers monkeypox vaccine at an outdoor walk-in clinic in Montréal, on July 23, 2022. It is crucial that people who have been exposed to monkeypox get vaccinated if they do not yet have symptoms, or isolate if they do have symptoms.

To control monkeypox, there is a short window — weeks, not months — in which to vaccinate the most susceptible and to encourage and support self-isolation for those who have symptoms.
