The mRNA metabolism passively shapes the levels of an mRNA modification called m6A within a steady-state cell and upon stress.

What we know about the safety, efficacy of mRNA vaccines amid recent scrutiny Vaccines using mRNA technology have been studied for decades, experts say.

The mRNA in the vaccine is soon destroyed by the cell – just as any other mRNA would be. The mRNA cannot get into the cell nucleus and it cannot affect a person’s DNA.

Normally, mRNA is produced in the nucleus in a process called transcription, but in the case of mRNA vaccines, it enters cells within a lipid-based protective bubble.

Infectious disease experts say mRNA vaccines have been studied for decades, they are safe and effective, and were instrumental in saving lives during the COVID pandemic.

After being demoted and forced to retire, mRNA researcher wins Nobel Katalin Karikó and Drew Weissman awarded Nobel Prize in Physiology or Medicine.

The three types of RNA are found in different locations. mRNA is made in the nucleus, with each mRNA fragment copied from its relative piece of DNA, before leaving the nucleus and entering the ...

This week, mRNA vaccines are set to face intense scrutiny from critics in Congress. Here's an explainer of how we know they are safe and effective.

Why are mRNA vaccines being used now? In the mid-2000s, scientists at the University of Pennsylvania figured out how to get foreign mRNA into human cells without it degrading first.

A viral video claims COVID vaccines change recipients’ DNA, making them no longer human. Experts say this is nonsense: mRNA cannot reach cells' DNA.
