Vaccinations for COVID-19 began being administered in the U.S. on Dec. 14, 2020. The quick rollout came a little more than a year after the virus was first identified in November 2019. The impressive speed with which vaccines were developed has also left a lot of people with a lot of...
The Pfizer and Moderna vaccines are bothmRNA (messenger RNA) vaccinesthat trigger an immune response. They use mRNA to instruct cells to make a harmless snippet of the spike protein that is found on the surface of the SARS-CoV-2 virus, which causes COVID-19. This protein triggers an immu...
In the case of the COVID-19 vaccines, instead of injecting a weakened or dead virus into the body, the mRNA causes the body to make a piece of the virus in order to create an immune response. The manufacturing time is only a fraction of that involved in developing a traditional vaccine...
History of mRNA vaccines mRNA vaccine is based on the principle that mRNA is an intermediate messenger to be translated to an antigen after the delivery into host cells via various routes. RNA molecules have been utilized as therapeutic and research tools for more than two decades, with the ...
one question that continues to intrigue many is how are EVs able to evade the phagocytic immune cells while also being effectively internalized by the target cell or tissue. While some of the components that facilitate this process have started to be identified, many mechanisms are yet to be di...
Thousands of vaccines are administered every day and the vast majority induce few symptoms in the recipient. Those symptoms that do occur early after vaccination are usually mild and self-limiting and rarely have serious medical consequences. Nevertheless, understanding the range of symptoms that vaccin...
(intentionally due to the spike protein) for as much as 150 months. And that after enough jabs are administered to that body it results in a total breakdown of said immune system. Now stop and consider that the recommendation is not for one shot (like with many real vaccines), you are ...
The Oxford-AstraZeneca COVID vaccine uses the viral vector method, while the Moderna and Pfizer-BioNTech vaccines use mRNA. The benefits of vaccines As you might expect given the long history of vaccinations, there have been many studies into the benefits and side effects of vaccines. ...
mRNA based vaccines have been widely used in a variety of diseases such as cancer and infectious diseases. These vaccines also encompass a considerable portion (17%) of developing vaccines, which are under clinical trials for COVID-19. The mRNAs developed against MERS-CoV and SARS-CoV mostly ...
With such an unprecedented, risky vaccine, it is not surprising to see so many unexpected serious adverse events since the launch of the first COVID-19 vaccine in early 2021. “Vaccines are safe and effective” has been the ongoing irrational mantra of the past two years, recycled ...
