NO. 6 Viral Vector Vaccine – Seven Type COVID-19 Vaccines Leave a comment

Hello friends, this is Gary, a perseverance import and export trade manager. Welcome to back our channel. Let’s continue our COVID-19 vaccines types, today we introduce, this one, the Viral Vector vaccine.

This type of vaccines working mechanism same as live attenuated vaccine, but this time use adenovirus as a carrier.

Use adenovirus to carry spike protein to stimulate our body, product antibody. Use adenovirus can not co-stimulate the immune system, but can strong immunity ability.

Ok, let check the evaluation details.

Technology maturity? Due to this vaccine technical only success on EBOLA vaccine, so give this item only three star.

The representative products, one product, one star.

Safety item, I do no know how to evaluate, due to reference tell me “have potential safety risks”, so maybe 3 star.  This just a reference, if I am wrong, please let the message tell me.


The development speed, according to reference no such mentions, so leave this blank, but production speed is faster. So I give it four stars.

According to the reference, this type of vaccine technical have high efficiency and can stimulate two immunity to respond. And can deliver to any target organs.

But the cons, have potential safety risk. And this type of vaccine needs a high operation and production technology.

The final cons, that, if you have Antibody for Adenovirus before, this maybe can not work for you.

OK, until now, we introduce five types of vaccine, two use the cell to stimulate antibody, three use the spike protein, maybe use different carrier. But the main use for spike proteins.

Next time I will discuss the mRNA and DHA, the third generation vaccine technology.

Finally, if you like our video, like and subscript,  ok see your next video.
