Stay away from either viral vector or mRNA active vaccines. Those are the culprits here. Producing spike proteins or "harmless" copies of the virus itself in your body to trigger a response of your immune system.

That is like setting your sofa on fire in your house and try learning putting out fires that way.

Passive vaccines aka inactivated virus vaccines are the safe choice here if you absolutely need to take the shots for travel purposes.

Those are not going to command your body to produce anything but just to passively trigger with inactivated viruses a response.

That is like setting a controlled fire inside an oil barrel, knowing very slim chances of that getting out of control.
