A subcommittee of the Senate Homeland Security Committee is set to scrutinize the safety and efficacy of messenger RNA (mRNA) vaccines this week, amid growing doubts about their use. The hearing comes as some US state legislatures consider banning these vaccines and the Trump administration investigates funding for mRNA research.
Critics are questioning the safety of mRNA vaccines, which were instrumental in combating the worst pandemic in a century. The vaccines have already led to a Nobel Prize win. However, concerns over myocarditis and other adverse events associated with COVID-19 vaccines have sparked intense debate.
The federal government recently announced plans to shift its focus to developing universal flu and coronavirus vaccines using chemically inactivated whole viruses. This move has raised fears that funding for mRNA research could be affected.
