Despite 22 active research projects aimed at advancing mRNA vaccines against various diseases, Kennedy claims the technology is ineffective against respiratory infections like COVID-19 and the flu - a stance that contradicts existing scientific evidence.

Research shows mRNA vaccines saved millions of lives during the COVID-19 pandemic.

The Department of Health and Human Services plans to cancel contracts and pull funding for some vaccines being developed to fight respiratory viruses like COVID-19 and the flu.

The Bill & Melinda Gates Foundation is announcing $40 million in funding to help develop messenger RNA vaccines in Africa.

The Nobel Prize in Medicine has been awarded to two scientists whose work led to mRNA vaccines against COVID-19.

Two scientists have won the Nobel Prize in medicine for discoveries that enabled the creation of mRNA vaccines against COVID-19 and that could be used to develop other shots in the future.

China is trying to navigate its biggest coronavirus outbreak without a tool it could have adopted many months ago, the kind of vaccines that have proven to offer the best protection against the worst outcomes from COVID-19.

In early 2020, the coronavirus was spreading across the globe and nobody knew how to stop it.

Pharmaceutical company BioNTech says it wants to use the mRNA technology behind its coronavirus vaccine to target malaria.

Texas has been administering the COVID-19 vaccine for four months and there are still myths running rampant.

In a rare acknowledgement, China’s top disease control official says current vaccines offer low protection against the coronavirus and mixing them is among strategies being considered to boost their effectiveness.

How could scientists race out COVID-19 vaccines so fast without cutting corners? A head start helped -- over a decade of behind-the-scenes research that had new vaccine technology poised for a challenge just as the coronavirus erupted. Both shots -- one made by Pfizer and BioNTech, the other by Moderna and the National Institutes of Health -- are so-called messenger RNA, or mRNA, vaccines, a brand-new technology. U.S. regulators are set to decide this month whether to allow emergency use, paving the way for rationed shots that will start with health workers and nursing home residents. Traditionally, making vaccines required growing viruses or pieces of viruses — often in giant vats of cells or, like most flu shots, in chicken eggs — and then purifying them before next steps in brewing shots.
