The black-legged tick is the vector that spreads Lyme disease. Its bite can infect humans with the Borrelia burgdorferi bacterium.
The bacterium that causes Lyme disease is a master of disguise, changing its appearance to evade the immune system as it moves from the ticks that carry it to humans or animals.
Broad protection from a universal flu vaccine could replace seasonal flu shots.

Annual flu vaccines are in a constant race against a rapidly mutating virus that may one day cause the next pandemic. A one-time vaccine protecting against all variants could give humanity a leg up.
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.
Imaging the proteins on the surface of HCV has been challenging because of the virus’s shape-shifting nature.

Using a Nobel Prize-winning technique called cryo-EM, researchers were able to identify potential areas on the hepatitis C virus that a vaccine could target.
Funding research is essential to meet future health challenges.
Canadian scientists have made significant contributions during the pandemic response, including vital roles in developing COVID-19 vaccines. But underfunding puts the future of science in Canada at risk.
New boosters protect against the original COVID strain as well as Omicron. In future, we might see variant-proof vaccines or those delivered in the nose or mouth.
Inhaled vaccine delivery could take on not only COVID-19, but also other respiratory infections, including tuberculosis.
An inhaled COVID-19 vaccine would go directly to where the body would use it: the mucosal surface of the airways. This could mean less waste and more benefit, lower costs and reduced side-effects.
A new network of public clinical trials institutes is urgently needed to replenish the empty pipeline for new antibiotics.
Various strategies are being pursued to boost worldwide vaccine coverage.
It sounds too good to be true, a vaccine that can protect against future virus variants. But governments around the world are keen to learn more.
Increasing skills and the availability of raw materials would be a bigger boost for vaccine production right now.
Skyrocketing demand coupled with shortages of vital components is leading to bottlenecks in the supply chain of Pfizer’s and other mRNA vaccines.

The R21 vaccine protected three-quarters of children against malaria in trials.
We have two mRNA COVID-19 vaccines so far. But what else can this technology do?
Universities are the unsung heroes of vaccine development.

The development of the COVID-19 vaccines is part of a vast system of public subsidies and universities, not corporate ambition.
Wouldn’t it be nice if one shot could protect you for life?

You need a new shot every year because current flu vaccines provide limited and temporary protection. But researchers’ new strategy could mean a one-and-done influenza vaccine is on the way.

Tuberculosis is a global threat and a public health concern on a scale similar to COVID-19.

What normally takes decades has been achieved in 12 months, without cutting corners.
On Dec. 8, 2020, the first members of the public were given doses of a coronavirus vaccine.

The coronavirus vaccine was developed faster than any vaccine in history. It took just 332 days from the first sequencing of the virus genome to the first vaccines given to the public.
The pharmaceutical industry opposes the suspension of intellectual property rights on COVID-19 vaccines and treatments, and no pharma companies have yet contributed to the COVID-19 Technology Access Pool.
We should applaud drug companies for developing COVID-19 vaccines in record time, but let’s not be under any illusion about the profits that are motivating them.
