In accordance with the WHO Prioritization Roadmap, Scientists engineer a harmless adenovirus (a common virus that, when not inactivated, can cause colds, bronchitis, and other illnesses) as a shell to carry genetic code on the spike proteins to the cells (similar to a Trojan Horse). Even though Pfizer-BioNTech and Moderna mRNA vaccines are safe and highly effective, weve heard a lot of people say the reason they've chosen not to get an mRNA vaccine is because the mRNA technology is relatively new and it hasn't been tried on a wide scale before., There are practical reasons as well. The immune system will then attack the spike protein the next time it sees one (attached to the actual SARS CoV-2 virus). "The mRNA platform is far more modifiable than what Novavax does," he said. It is simpler to make than some of the other vaccines and can be stored in a refrigerator, making it easier to distribute.
