mRNA VACCINES, EXPLAINED.

Researchers working on Covid-19 vaccines have smashed speed records, bringing new vaccines from development to distribution in less than a year. They did this with the help of billions of dollars of unprecedented global investment -- but also, in some cases, with a new type of vaccine technology.

There are four traditional types of vaccines, and they all require the growing and handling of live pathogens in a lab, a time-consuming process than can add months or years to development. But two new types of vaccines skip that step altogether by moving that work from the lab to our bodies. mRNA vaccines, like the ones from Pfizer-BioNTech and Moderna; and Adenovirus vaccines, like those from Johnson & Johnson and AstraZeneca; do this by sending genetic instructions directly into our cells, which then produce the harmless protein the body needs to learn to fight Covid-19. Because these proteins are produced from within cells rather than injected from the outside, they may be less likely to provoke adverse reactions in the recipient.

The result has been a host of vaccines developed faster than ever. But it's also ushered us into a new age of vaccine technology, one in which we can send our own bodies the instructions on how to protect themselves. That technology is already being used to drive research on vaccines for HIV and cancer. These new types of vaccines are weapons we developed to fight the coronavirus - but their real impact is just beginning.

Germany and Canada have suspended the AstraZeneca due to blood clots in under 55, can you expound on that Daktari.
Those fall in the realm of what’re called adverse drug reactions. Their very nature is such that they’re often idiosyncratic and due to the small numbers of people used during clinical trials, will often not manifest at that time.

It however is worth mentioning that that drug that has no adverse effects has not yet been made. All drugs have adverse drug reactions. ALL.

A slight correction: Germany has restricted administration of the AZ vaccine to only those aged above 60yrs.

Wewe ni dakatari so I cannot argue my case with any authority. However, explain to me how is it so different to what scientist do with gmo's by introducing genes into plants using A. tumefaciens so that they express a preferred characteristic and what we are doing with mRNA vaccines.

Aren't you conditioning cells to produce foreign proteins? Won't white blood cells attack these cells? When do these cells finally stop producing these foreign proteins?

Dagitari, the above makes people like me who already took the jab weeks ago apprehensive, do they know something that we don't or it's something else.

Form 4 biology: natural and artificial immunity, active and passive in both cases.

Natural active acquired immunity is when your body forms antibodies against a disease to which you have been exposed, where you actually got ill and recovered.
Artificial active immunity is acquired via vaccination, where your body makes antibodies against an organism as intended by the vaccine.
In these cases, there's absolutely no change to the host cell DNA so the issue of GMOs does not arise.

Vaccines condition your body to produce antibodies against foreign proteins, not against self proteins. All these covid vaccines are priming the body to recognize and produce antibodies against the covid virus spike protein and thus prevent the virus from gaining access to the host cell.

Suggested further reading: look up the viral life cycle.
Note that we have two types of viruses, DNA (e.g. hepatitis B) and RNA (e.g. hepatitis C).

Mbona nilikuwa mvivu kwa shule ningekuwa na elewa nini umesema🙄
