Waiving patent rights on COVID-19 vaccines and drugs is still crucial to ensure access globally, but the waiver on the table at the June World Trade Organization meeting doesn’t do the job.

Existing coronavirus vaccines are not as effective against newer variants of the virus. Two vaccine experts explain how new vaccines currently in development will likely offer better protection.
Although the COVID-19 vaccines have saved millions of lives, they have been insufficient at preventing breakthrough infections.

The COVID-19 pandemic has brought immunology terms that are typically relegated to textbooks into our everyday vernacular. These stories helped us make sense of the ever-evolving science.
Researchers are working to develop vaccines that provide long-term immune protection from COVID-19.

We’re reliant on overseas supply - and the many moving parts of delivery. Each of those parts require staff on the ground – and many workers in this system are likely being affected by Omicron.
mRNA vaccines: not just for COVID.

Some vaccine hesitancy is based on a fear of the nanoparticles used in mRNA vaccines. But humans have been interacting with nanoparticles for millennia, and we use nanotechnology-based devices every day.
A vaccine manufacturing facility will be built in Victoria to produce mRNA vaccines under an in-principle agreement between the federal government, the state government and global mRNA company Moderna
COVID-19 vaccines have been proved safe and effective. But it’s understandable to have questions.

Each dose of Pfizer has a long and complex path involving mixing, storage at temperatures colder than the South Pole and specific protocols that must be followed before it becomes a jab.

With youth ages 12 and over eligible for COVID-19 vaccination — and as trials for younger children move ahead — parental hesitancy is emerging as the new challenge for COVID-19 vaccine programs.
New Zealand’s approval of Pfizer’s COVID-19 vaccine for 12-15 year olds will bring the number of people eligible for the jab to 85% of the population, raising the chance of reaching collective immunity.
One of this and one of that might be a good strategy to coronavirus vaccination.

Various companies use different ingredients and different delivery systems in their COVID-19 vaccines. Researchers are investigating whether it’s better for individuals to mix what’s available.

Hundreds of thousands of Canadians got a shot of AstraZeneca’s COVID-19 vaccine for their first dose. They now have a choice for their second dose: AstraZeneca again, or Pfizer or Moderna mRNA vaccine?
Canadian public health organizations have run into a serious communication problem about the AstraZeneca vaccine. Crisis management and communication theories explain what’s gone wrong.
