Experts have long understood that a new polio vaccine developed to try to minimize the risks associated with the oral polio vaccine made by Albert Sabin might also cause the problem it was created to sidestep. It’s now clear that theoretical risk is a real one.

A study of parents of children aged 5-11 in Italy showed that black-and-white thinking was associated with the tendency to believe in conspiracies. This was in turn associated with a negative attitude towards vaccinating children against COVID-19. The study was published in Applied Cognitive Psychology. ...

People who frequently interact with low-quality news websites tend to express more reservations about COVID-19 vaccines, according to new research that examined behavior on the social media platform Twitter. The findings have been published in the scientific journal PNAS Nexus.

A Hong Kong-based bank is offering new and existing customers an express reservation for a complimentary BioNTech/Pfizer mRNA vaccine if they deposit at least HK$4,000,000, or about $512,200, into an account. The vaccine is being offered as mainland China lifts its cross-border restrictions with Hong Kong and is among a number of "privileges" China CITIC Bank International, which is held by Chinese state-owned CITIC Group, is rolling out until March 31.

The US has approved use of the world's first vaccine for honey bees. It was engineered to prevent fatalities from American foulbrood disease, a bacterial condition known to weaken colonies by attacking bee larvae. The US Department of Agriculture (USDA) approved a conditional license for the vaccine this week, according to the biotech firm behind its development.

BioNTech has finally dosed the first patient with its Herpes Vaccine (BNT163) in a candidate clinical trial. According to the German Vaccine maker, “The vaccine is designed to prevent genital lesions as part of a first-in-human Phase 1 clinical research study.”

Researchers say they have successfully completed a trial of a personalised cancer vaccine that uses the same messenger-RNA technology as Covid jabs. The experimental vaccine, made by Moderna and MSD, is designed to prime the immune system to seek and destroy cancerous cells. Doctors hope work such as this could lead to revolutionary new ways to fight skin, bowel and other types of cancer.

Measles vaccination coverage has steadily declined since the beginning of the COVID-19 pandemic, according to a report published on Nov. 23 by the World Health Organization (WHO), the United States Centers for Disease Control and Prevention (CDC) and several university researchers, including Matthew Ferrari, director of the Center for Infectious Disease Dynamics at Penn State. Specifically, in 2021, a record high of nearly 40 million children missed a measles vaccine dose, with 25 million children missing their first dose and an additional 14.7 million children missing their second dose.

When COVID-19 was filling emergency rooms, shuttering businesses, and turning parents and teachers into experts in Zoom, everyone hoped for a cure — or, if that wasn't possible, at least a way to avoid getting it. However, when a vaccine became available, many were wary of it. Rumors quickly spread about "the jab": It gives you cancer. It was approved before enough research could be done. It restructures your DNA. All these are false, according to Memorial Sloan-Kettering Cancer Center, but that hasn't stopped the rumor mill from grinding.

Uğur Şahin and Özlem Türeci say mRNA Covid vaccine technology could be repurposed to help destroy cancer cells.

A malaria vaccine with "world-changing" potential has been developed by scientists at the University of Oxford. The team expect it to be rolled out next year after trials showed up to 80% protection against the deadly disease.

You may have heard last week that Moderna is suing Pfizer, claiming that Pfizer’s COVID vaccine violates Moderna’s patents. You can read the legal complaint which is full of bluster abo…

To date, seasonal flu vaccines have protected against only specific strains that scientists predict will be the most widespread each year.

Among almost 43 million people in England who received at least one COVID-19 vaccine dose, the risk of myocarditis was substantially higher in the four weeks after COVID-19 infection than after a first dose of a COVID-19 vaccine, according to new study in Circulation.

Some scientists are alarmed that the agency plans to evaluate the next generation of boosters by reviewing mouse studies alone. Others say there's no time to waste waiting for human trials.

Original court documents tell a different story than the one contained in a viral blog post from a convoy-friendly National Post columnist.

Pro-vaccination messaging may be surprisingly effective when delivered through humorous internet memes, according to new findings published in the journal Computers in Human Behavior. A series of studies revealed that exposure to sarcastic memes about anti-vaxxers increased UK residents’ intention to receive a COVID-19 vaccine. The researchers suggest that the humorous memes were able to bypass the typical defense processes of people who are vaccine-hesitant.

An independent panel of experts advising the US Food and Drug Administration just voted unanimously "yes," expressing their confidence that a two dose COVID-19 vaccine from Moderna is safe, effective, and beneficial for youngsters as little as 6 months old, and that a three dose COVID shot from Pfizer is too.

Phase I study shows that mRNA-based vaccines can be used to stimulate T cells to recognise neoantigens in pancreatic cancer patients.

When the World Health Organization approved a malaria vaccine for the first time in October 2021, it was widely hailed as a milestone. “This is a historic moment,” said WHO director-general Tedros Adhanom Ghebreyesus in a statement that month. The vaccine—dubbed RTS,S—promises a 30 percent reduction in severe malaria in fully vaccinated children.
