COVID-19 vaccines for children: How parents are influenced by misinformation, and how they can counter it

Pediatricians and other health care providers can take some concrete steps toward building trust and counteracting anti-vaccination misinformation.

After a year of COVID-19 vaccine mandate outrage, is there more ahead?

Conversations and debates about vaccine mandates will continue well into next year as policy-makers balance individual freedom and public well-being.
While people in the wealthy West have had preferred access to multiple rounds of vaccines, vast numbers of people, especially in Africa and on the Indian subcontinent, haven’t received a single dose. (Pixabay/Canva)

COVID-19 vaccine inequity allowed Omicron to emerge

In places with low vaccination rates, COVID-19 has the chance to linger, and variants develop and travel. Without global vaccine equity, this entirely predictable pattern will repeat itself.

How can scientists update coronavirus vaccines for omicron? A microbiologist answers 5 questions about how Moderna and Pfizer could rapidly adjust mRNA vaccines

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.

Reverse vaccination technique in mice suggests new way to teach the immune system not to attack lifesaving treatments

A recent lab-stage study finds that preexposure to the proteins used to treat conditions like hemophilia A could help train the immune system to tolerate rather than attack therapies.

US vaccine rollout was close to optimal at reducing deaths and infections, according to a model comparing 17.5 million alternative approaches

With limited vaccines available in early 2021, the CDC had to decide which people received vaccines first. With the help of a supercomputer, researchers have shown that the CDC did an excellent job.

How cognitive biases and adverse events influence vaccine decisions (maybe even your own)

To help increase trust in vaccines, researchers analyzed data on adverse events to address safety concerns, and then used cognitive science to show how cognitive biases feed vaccine hesitancy.
