Several widely circulated posts claim that the spike protein mRNA in COVID-19 vaccines and the lipid nanoparticles (LNPs) that transport the RNA to the cells are harmful. One post claims that the mRNA in the vaccine “hijacks” cells, causing them to produce “poison” spike protein indefinitely.
The persistence of misleading and false claims about mRNA vaccine safety increases the risk. Emphasizing that ingredients in COVID-19 vaccines are nontoxic is recommended. COVID-19 vaccines use LNPs to deliver intact mRNA to the cells and then instruct the cells to produce a spike protein, which is not harmful to humans.
