Vaccines

A three-year study has found robust evidence that one vaccine for respiratory syncytial virus offers older adults long-term protection, even if efficacy wanes. Despite this, just one dose cut serious illness by nearly two thirds across three seasons.

Taking advantage of a unique public health policy in the UK, a new study has found that receiving the shingles vaccine reduces dementia risk by 20%. The findings bolster growing evidence linking the vaccine to lower numbers of dementia cases.

Human protection against bird flu may be easier than previously thought, thanks to new findings about the genetic makeup of the virus and one particular immune cell that all of us have. It also paves the way for fast-tracking the first H5N1 vaccine.

We've almost all been hit with a horror stomach bug. At best, it's a 24-hour nightmare, and at worst it's deadly. But huge strides are being taken towards the first Salmonella and norovirus vaccines, which could make severe illness a distant memory.

The US has recorded its first death due to avian influenza. The man had been infected by a H5N1 variant with a genetic mutation, helping it target upper respiratory tract receptors – one also seen in the Canadian teen who fell critically ill last year.

If you were given a choice of vaccine delivery method, would you rather a needle or a skin cream? Thought so. Well, the latter might be a viable option soon, as Stanford scientists have used a topical cream to strongly vaccinate mice against tetanus.

Mosquitoes do a superb job of spreading diseases like malaria – now researchers have shown it's possible to hijack these pests and distribute vaccines via mosquito bite. In human trials, these mozzie-borne vaccines proved around 90% effective.

Measles is on the rise, attributable to the anti-vaccination movement and exacerbated by the COVID-19 pandemic. Researchers have identified a new way of tackling one of the most contagious viruses around, offering protection for those at greatest risk.

Glioblastoma is one of the most deadly cancers, with few treatment options available. Now, a small human clinical trial has demonstrated an mRNA vaccine that quickly rallies the immune system to fight off the tumors, with promising results.

An oral vaccine that prevents urinary tract infections (UTIs) recurring has shown to provide protection for nearly a decade in a majority of patients, according to a new study. This easy treatment offers a safe, effective method of UTI prevention.

A single-shot vaccine that protects against multiple coronaviruses, including the one that causes COVID-19, has been developed. It erased all viral traces from the lungs of animal subjects, opening a pathway for a similar human vaccine.

The biggest tragedy of pet ownership is that they just don’t live long enough. Thankfully scientists are working on that, with a new cancer vaccine for dogs that almost doubles their survival rates in the face of certain types of the disease.
