>> don’t yu know the difference between an mRNA vaccine and an adenovirus vaccine? geesh. take the propaganda elsewhere <<
That’s just it... No mRNA vaccine has ever been properly studied for safety, because it’s a brand new technology, expanding the definition of “vaccine.” J&J’s effectiveness may be unknown, but since it’s a more traditional vaccine, it’s harder to suppose unforeseeable harm.
mRNa vaccines have been researched for over 40 years, a majority of that research funded by the NIH and done by the real pioneer, Katalin Karikó:
“But here is where another decades-long scientific effort paid off: Concern about another influenza pandemic on the scale of the 1918 flu pandemic has long motivated U.S. investment in flu studies, particularly by the NIH. The NIH has also spent more than 40 years funding scientists working toward a vaccine for HIV.
“The crucial sequence information needed to target COVID-19 came from a vaccine research laboratory at the NIH. The lab had been working on HIV vaccine designs for decades and had developed algorithms to identify molecular structures optimized for vaccines. This approach also predicted a successful vaccine structure against the respiratory syncytial virus. Harnessing that experience, the NIH group rapidly identified stable molecular structures optimized for the mRNA vaccines against COVID-19.
“4. NIH investment in vaccine evaluation infrastructure pays off
For 60 years, the NIH also has maintained a group of about 10 university laboratories throughout the country to help test vaccines against pathogens...”
...America’s ability to rapidly produce COVID-19 vaccines did not result from luck or a short-term effort. The mRNA vaccines we have today were birthed from decades of investment and determination. Karikó’s tenacity still endures today...”
