Could mRNA COVID-19 vaccines be dangerous in the long-term?

The Jerusalem Post:

‘There is a race to get the public vaccinated, so we are willing to take more risk.’

Israelis celebrated on Friday when Prime Minister Benjamin Netanyahu announced that the country had signed a deal with Pfizer Inc. to buy its novel coronavirus vaccine.

But the fact remains that if Pfizer succeeds – or Moderna, with whom Israel also has a contract – these will be the first-ever messenger RNA (mRNA) vaccines brought to market for human patients.In order to receive Food and Drug Administration approval, the companies will have to prove there are no immediate or short-term negative health effects from taking the vaccines. But when the world begins inoculating itself with these completely new and revolutionary vaccines, it will know virtually nothing about their long-term effects.

“There is a race to get the public vaccinated, so we are willing to take more risks,” Tal Brosh, head of the Infectious Disease Unit at Samson Assuta Ashdod Hospital, told The Jerusalem Post. When Moderna was just finishing its Phase I trial, The Independent wrote about the vaccine and described it this way:

“It uses a sequence of genetic RNA material produced in a lab that, when injected into your body, must invade your cells and hijack your cells’ protein-making machinery called ribosomes to produce the viral components that subsequently train your immune system to fight the virus.”“In this case, Moderna’s mRNA-1273 is programmed to make your cells produce the coronavirus’ infamous coronavirus spike protein that gives the virus its crown-like appearance (corona is crown in Latin) for which it is named,” wrote The Independent.

Brosh said that this does not mean the vaccine changes people’s genetic code. Rather, he said it is more like a USB device (the mRNA) that is inserted into a computer (your body). It does not impact the hard drive of the computer but runs a certain program.

But he acknowledged that there are unique and unknown risks to messenger RNA vaccines, including local and systemic inflammatory responses that could lead to autoimmune conditions.
