Speaking of mRNA and its unknown long term side effects, I chanced upon this ST report on a local research shows  that traditionally-created non-mRNA vaccines such as Sinopharm and Sinovac has a  "broader" immune response against different proteins on the virus since it is based on natural gene imprint to generate immunity than artificial mean as done in mRNA technique.

Broader immune respone is very logical to me. It is like you are teaching a young kid who has never seen a rambutan. You can cut out the rambutan "hairs" (like the protein spikes of the covid virus) and tell him to use them to recognise the fruit , but best teaching method will still be to show him/her the whole fruit.

But inactivated virus vaccine yields a lower antibody response, so one should always wear a mask to reduce the virus intake to allow time for the immune system to warm up to fight the viruses that replicates (exponentially?) within the body.
