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.
South Africans wait for access to a COVID-19 vaccine.
New research sheds light on how Canadian researchers developed a key component of the mRNA COVID-19 vaccines but failed to share it with the world
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.
Research suggests that about 20% of all prescriptions are administered “off-label.”

An infectious diseases doctor reviews the evidence, discusses hesitancy and concerns about side-effects and explains the overwhelming case for vaccinating five-to-11-year-olds, including his own son.
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.
For many parents, the long-awaited COVID-19 vaccine authorization for younger kids can’t come soon enough.

Pediatric clinical trials for the COVID-19 Pfizer vaccine for children ages 5 to 11 have shown that the Pfizer shot is safe and effective.
Discuss with your doctor whether or not you need a booster – and if so, which vaccine will work best for you.

As boosters are authorized for all three COVID-19 shots available in the US, the ability to swap out vaccine types looks to be a boon to the immune system.
With the government decision on alert levels due today, it’s clear a more radical approach to vaccination is needed — including restrictions for eligible but unvaccinated people.
The FDA and CDC are recommending use of a third shot, or “booster dose” for certain groups of people in the U.S.

Fault lines between the FDA and CDC regulatory processes have been on full display in the decisions over which groups of Americans should receive the Pfizer booster shot.
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.
