“An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response” – Wikipedia
It is a new type of developing vaccines. Earlier vaccines were developed in another way, it is called vector vaccine
“You take a virus [vector] – a harmless, non-intruding into the genome, with which all humanity encounters during its life – adenovirus. Then you make him even safer – you cut off a piece of his genome, or rather two.” – Deputy Director for Scientific Work of the Center. Gamalea of the Ministry of Health of Russia Denis Logunov.
Today there are two mRNA vaccines: Pfizer and Moderna. Both of them against Covid-19.
So, the important question is why this technology is so important or innovative? I will give you an answer in this blog.
Firstly, vaccines that were made in mRNA way could be easily modified for new virus stamps. Secondly, they are more effective than vector vaccines (effectiveness of Pfizer and Moderna more than 95% while vector vaccines have less than 90%). The third thing is that this technology gives us hope that in future we could get vaccines against Cancer, HIV and other serious illnesses.
The opposite view is that this technology is young, just few years. No one knows how it will affect our health in future, so that why using such vaccines should not be introduced by force or by threat. A person should introduce it if he wants to.
My personal view is that this technology started well and will provide to humanity with a lot of good things and will save great amount of people. And i was vaccinated by Pfizer , because i belive in this technology.
mRNA vaccines are the future of vaccines indeed! As a person who is very interested in medicine (even took HL Biology) I got really into the technology that stays behind that revolutionary invention in medicine.
mRNA are indeed much better alternative for people who want to get vaccinated but they can’t take the vector vaccines – that’s the case of people with autoimmune diseases for whom vector vaccines with the adenovirus in them is not a possibility – why? because it can create even bigger harm to them.
It is unbelievable how they have found a way to create mRNA COVID vaccine so fast… because for a few years so far mRNA vaccines are being created for HIV and some types of cancers but sadly with no progress so far.
