The new mRNA vaccines target the KP. 2 variant because most recent covid cases are caused by that strain or closely related ones. The Novavax vaccine targets the JN. 1 variant that recent variants ...

“We figured out how to stabilize coronavirus spikes back in 2016, so we had all the knowledge ready when Covid-19 emerged,” McLellan said. It was ready to go “within hours,” he said.

The CDC says "cancer research has used mRNA to trigger the immune system to target specific cancer cells." Similar to other vaccines, the COVID-19 mRNA vaccines are given in the upper arm muscle.

For example, the mRNA in the novel coronavirus behind Covid-19 enables a “spike protein” that pierces cells throughout the body.

It’s true that mRNA vaccines would probably have come to market eventually, but they were on what Dieffenbach calls “a leisurely stroll.” Covid “pressure-tested” them—advancing their ...

On Tuesday, the U.S. Food and Drug Administration announced plans to limit access to future COVID-19 shots -- two of which are mRNA vaccines -- to those aged 65 and older or with high-risk conditions.

Duchenne Muscular Dystrophy, pulmonary fibrosis, scleroderma and COVID lung are all caused by a hardening of vital tissues, noted Weissman, who is now using mRNA as the basis for an experimental ...

Indeed, an mRNA vaccine has never been mass-produced and licensed to treat an infectious disease. The mRNA vaccines to treat the novel coronavirus would be the first.

Now that COVID-19 vaccines have proved the mRNA approach can work, there should be much more enthusiasm – and money – to pursue other mRNA vaccines and therapies.

Weissman’s lab is now working on a universal coronavirus vaccine that would protect against Covid-19, SARS, MERS, coronavirus that cause the common cold – and future strains.
