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.

An infectious disease doctor explains the science behind COVID-19 vaccines at a level that children – and adults – of all ages can understand.
Trials are under way to ascertain whether COVID vaccines are safe and effective for children under 12. In the meantime, it’s reassuring to note that generally, young kids cope OK with the virus.
The federal government has announced the Pfizer vaccine will be available to all Australians from August 30. Though there may well be long waits.
Full FDA approval of the COVID-19 vaccines may help people feel more secure in its safety and effectiveness.

While emergency use authorization gets vaccines out to the public more quickly, it doesn’t skip any steps that full approval requires.
Doses of the Moderna vaccine will be available in Australia from mid-September. So if you’re in an eligible group you could be offered either Pfizer or Moderna. Here’s how they compare.
