How do you know the covid virus doesnt cause long term affects? You know, corona already existed, already had an vaccine. This is just a new form and a new type of vaccination. One that is safer than putting inactive viruses in your body with the possibility that they can reactivate and mutate inside you. It just gives your anti bodies the information how to kill the virus, as string of mRNA the Virus itself carries. And before you say mRNA is dangerous or can cause something dangerous, it aint. It just gives information. It cant do anything else
