Hi,

Chinese scientists have launched a strong shield against helicobacter pylori.

(This comes from an English study book in Chinese. There is the only one sentence without more context.)

Is it OK to say "launch a strong shield"? I've searched the Internet but I didn't find one. Can I use "build a strong shield"?

Thanks in advance!

    No, it's a mixed metaphor. Space-based missile defences could be a shield and be launched, but I wouldn't apply that to metaphorical situations.

    Sorry, could you please explain it in details?
    Do you mean "a strong shield can be launched (meaning sent)"? And the use of "launch a strong shield" is not a metaphor?

    It seems to me that they have introduced a pharmaceutical product to guard against this bacterium. When you introduce a product to the market, we often call this launching the product.

    I first parsed this as helicopter pylon. :confused::)
