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.

Advisers to the U.S. Food and Drug Administration on Tuesday will consider whether to recommend Novavax Inc's (NVAX.O) COVID-19 vaccine for adults, which the drugmaker hopes can become the shot of choice among some American vaccine skeptics. Novavax's shot is a more traditional type of vaccine employing technology that has been used for decades to combat diseases including Hepatitis B and influenza.

The Brihanmumbai Municipal Corporation has announced that all eligible beneficiaries above the age of 18 in Mumbai have been fully vaccinated with two doses of Covid-19 vaccine. Mumbai has thus become the first major city in the country to fully vaccinate 100% of its citizens. It also has the highest vaccination coverage among all the 36 districts in Maharashtra.

The findings add further weight to the idea of mix-and-match boosting.

Two doses of COVID vaccine cut the risk of infection and mild illness from the rising BA.2 subvariant, although protection wanes quickly.

A new technology aims to stop wildlife from spreading Ebola, rabies, and other viruses. It could prevent the next pandemic by stopping pathogens from jumping from animals to people.

Phase 1 study is among first to examine mRNA technology for HIV.

Health care employees looking to skirt the federal vaccine mandate and claim a religious exemption need to do little more than submit a short request to human resources. Take Clark Fork Valley Hospital in western Montana. When the Biden administration’s vaccine requirement for health workers took effect earlier this month, roughly one-third of the hospitals’ workers were unvaccinated against Covid-19.

Amazon workers who catch COVID-19 and are not fully vaccinated against the virus will not be eligible for paid leave after March 18, according to a staff memo shared with Insider by Amazon. Thursday's memo also told workers they will no longer have to wear masks inside warehouses from Friday if they have been fully vaccinated and local regulations allow.

Gates pushed for a plan that would permit companies to hold exclusive rights to lifesaving medicines, no matter how much they benefited from public funding. Given the enormous influence Gates has in the global public health world, his vision ultimately won out in the Covax program—which enshrines monopoly patent rights and relies on the charitable whims of rich countries and pharmaceutical giants to provide vaccines to most of the world.

The US is expected to approve coronavirus vaccines for children under the age of five by the end of February. Pfizer asked officials at the Food and Drug Administration (FDA) on Tuesday to authorise two doses for the age group. The company is also researching a three-dose regimen but that data is not likely to be submitted until March.

Like most vaccines, RNA vaccines have to be injected, which can be an obstacle for people who fear needles. Now, a team of MIT researchers has developed a way to deliver RNA in a capsule that can be swallowed, which they hope could help make people more receptive to them.

A pair of studies in yesterday in Science show the substantial benefit of COVID-19 vaccination to household contacts in Israel, including unvaccinated children. But one of the studies highlighted waning protection over time.

Moderna announced Thursday that it's launched early-stage clinical trials of an HIV mRNA vaccine. The biotechnology company has teamed up with the nonprofit ​​International AIDS Vaccine Initiative to develop the shot, which uses the same technology as Moderna's successful COVID-19 vaccine.

The COVID-19 vaccines from Moderna and Pfizer are messenger ribonucleic acid (mRNA) vaccines, a relatively new form of vaccine technology. COVID-19 vaccines work by giving our cells instructions on making a SARS-CoV-2 protein. Our immune system reacts to these proteins and creates the necessary tools to deal with any future virus infection.

Howard Stern is calling on Meat Loaf’s family to speak out on vaccines following the rock icon’s death earlier this month. Meat Loaf died Jan. 20. TMZ reported at the time that the singer had been “seriously ill with COVID” and that “his condition quickly became critical.” It’s unknown at this time whether or not Meat Loaf was vaccinated against COVID.

More than two-thirds of the common side-effects people experience after a Covid jab can be attributed to a negative version of the placebo effect rather than the vaccine itself, researchers claim. Scientists in the US examined data from 12 clinical trials of Covid vaccines and found that the “nocebo effect” accounted for about 76% of all common adverse reactions after the first dose and nearly 52% after the second dose.
