There are few prevailing theories on what they put in the vaccines.
1. MRNA
2. Graphene and metals
3. MRNA + metals
What
@SusanB said about MRNA being killed by cooking is probably right. But what about metals?
That is in theory easy to disrupt as well. It is something called a "Microwave". Everyone has been oohing and ahhing at the mystery black box for years. What does it do? You put food in, press a few buttons, and voila!, after a nice light to illuminate your food and a humming sound to convince you it's doing something - it actually does something!
A Microwave is basically a wireless transmitter of electricity in this case. Such a amount that if you put forks and other metals in you'll see it sparking. Graphene for example is said to be a "wonder" material with amazing properties including an excellent conductor. While metals will remain, the original shape will likely be distorted. Few seconds, or maybe 10 seconds may be enough.
It's not a perfect strategy, but you may be able to disrupt whatever other reason they are putting those metals in, including simpler things such as binding to your cells, and the more far fetched creation of micro-bots in your body.
