On the horizon: A new omicron-focused version of the Moderna vaccine that may offer longer protection and a stronger immune response.
A new generation of vaccines and boosters against SARS-CoV-2 may take a page from the anti-influenza playbook, with shots periodically tailored to target the most commonly circulating virus strains.
New data on the second booster suggests the older you are, the more you need it.
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.
Flu vaccines will soon be available. And this year, you can get your COVID shot at the same time.
It’s too soon to recommend booster shots for younger children. But we can watch what’s happening in the US, where children as young as 12 are receiving theirs.
Booster shots are a common necessity for vaccines to keep working. Recent research shows COVID-19 booster shots are recommended for high-risk individuals — and may benefit the rest of us too.
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.
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.
An FDA panel has voted against recommending approval of a booster COVID-19 shot for the general population – disappointing some public health officials.
Scientists debate the medical benefits of booster shots. But there’s another aspect to consider: bioethics.
You’ll read lots of different figures on this — six months, eight months, more — and that’s because the research is ongoing. We don’t yet have a concrete answer.
Some countries have started administering third doses of COVID vaccines, or booster shots. But we’re still learning about how long immunity lasts from the first two shots.
A 2015 paper on chicken virus evolution is being taken out of context and used to fuel fears about COVID-19 vaccines. Its lead author aims to clarify the science in hopes of saving lives.
People with weakened immune systems are at a high risk of severe and prolonged COVID-19 infections. An extra vaccine dose can bolster protection.
There are two ways to look at it: self-interest versus altruism.
Though currently approved COVID-19 vaccines effectively provide immunity against the virus, it’s unclear how long that protection will last.
By the time Australia is ready to deliver Novavax, we may well have completed most of the vaccine rollout with AstraZeneca, Pfizer and Moderna. That doesn’t mean Novavax won’t play an important role.
An immunologist explains that you get some protection from the first dose of the mRNA vaccines but you need two to build up strong immunity, particularly to newer coronavirus variants.
Giving smaller vaccine doses in multiple shots is often more effective than a larger single dose.
