The new bivalent boosters against COVID-19 have failed to halt omicron infections. However, new technologies are being developed that pave a way forward.
Moderna is testing an mRNA vaccine in combination with pembrolizumab to treat melanoma.

Preventive and therapeutic vaccines both train the immune system to fight disease, but they are used in different ways.
In a matter of days, eligible people will be lining up to receive the newly formulated booster shot.

The CDC’s endorsement of the reformulated COVID-19 booster shots represents a major step in the effort to get more Americans boosted.
It’s natural to have questions about the risks and benefits of COVID vaccines in young children. Here’s what you need to know ahead of Australia’s rollout.
Clinical studies show that mixing and matching booster vaccines can lead to a more robust immune response.

On the horizon: A new omicron-focused version of the Moderna vaccine that may offer longer protection and a stronger immune response.
Millions of U.S. children between the ages of 6 months and 4 years will soon be eligible for COVID-19 shots.

The FDA’s authorization of COVID-19 shots for children ages 6 months to 4 years will bring relief for millions of parents. Pending CDC endorsement, shots for this group will be available within days.
Boosters and vaccinating children mean we’re relying on two pharmaceutical companies to supply Australia’s COVID vaccines. That needs to change.
The CDC recommends the second booster for those over 50 who received their initial booster shot at least four months earlier.

New data on the second booster suggests the older you are, the more you need it.
Parents can now choose Moderna to vaccinate their children against COVID. So how effective is it, and how does it compare with Pfizer?
Preliminary research suggests that the omicron variant may potentially induce a robust immune response.

Some of the omicron variant’s unique properties – such as its ability to spread rapidly while causing milder COVID-19 infections – could usher in a new phase of the pandemic.
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.
Some vaccines use mRNA to make copies of the triangular red spike proteins to induce immunity.

The new omicron variant of coronavirus has a number of mutations that may require manufacturers to update vaccines. The unique attributes of mRNA vaccines make updating them fast and easy.
There’s not enough evidence yet to support the AstraZeneca CEO’s statement. But it is theoretically plausible.
The U.S. government funded a significant portion of the R&D behind the Moderna vaccine.

Moderna claims its scientists alone invented the mRNA sequence used to produce its COVID-19 vaccine. The US government, which helped fund the drug, disagrees.
Ethics are important to vaccination decisions because while science can clarify some of the costs and benefits, it cannot tell us which costs and benefits matter most to us.

When making the decision whether to vaccinate children aged five to 11 against COVID-19, regulators in Canada must rely on sound ethics as well as sound science.
In the reluctance to vaccinate, there is a lack of trust and understanding of the scientific process. Better communication would help rebuild bridges.

Before the pandemic, the public perceived science as infallible and inaccessible. But the opening up of research to the general public has changed that perception.
mRNA technologies for vaccine production is gaining more prominence

Thanks to the collaborative efforts of governments, funding agencies, academia, biotech and pharmaceutical companies, large-scale manufacturing of mRNA drug products is becoming a reality.
People getting vaccinated may still have questions about COVID-19 vaccines, like why it takes two doses — and then two weeks — to take full effect.

A medical student answers questions he gets asked at a COVID-19 vaccine clinic: Efficacy versus real-world effectiveness, immune response and how the mRNA vaccines compare to vaccines already in wide use.
As we continue to roll out COVID-19 vaccines around the world, we’re learning people who are immunocompromised aren’t necessarily protected as well from the first two doses.
COVID-19 vaccines have been proved safe and effective. But it’s understandable to have questions.
