Antibodies to the original Covid won’t work against the delta variant as we are seeing. The delta is now the dominant strain. Immunity to delta will require natural immunity to delta (suffering Covid delta variant) or an updated vaccine.

Very clearly NOT TRUE to anyone paying attention. Hopefully, not too many will be gullible enough to believe your nonsense.
Israel is reporting 64% effective against delta.
Pfizer will start testing its new vaccine designed specifically for delta in August. They are ahead of the pack, as usual.
Bzzzzz. wrong. No candy for you! The antibodies to Wuhan’s Original Recipe can fight delta. Proof is in the low frequency of breakthrough infections. You are right that Delta is the new dominant (in urban areas iirc), and yes, the vaccine mfgrs are working or have developed an ‘update’ for Delta that will be in the booster shots). Since you got two of three right, you can have one piece of candy :)
you might find the below interesting. Pfizer is in booster trials, using Israeli numbers of 63% effective in preventing breakthrough to justify a booster, despite those numbers being challenged by 88% effectiveness in Canada, England and Scotland. The request for FDA Emerg authorization is being panned as premature.

With the Delta Variant, Do I Need a Covid Booster Shot?
...the world’s leading vaccine experts... note that all evidence suggests that the Pfizer shots, along with the Moderna and Johnson & Johnson vaccines, continue to provide strong protection against Covid-19.”
“...While the Pfizer vaccine and others in use in the United States are slightly less effective against the Delta variant, all of them still offer significant protection against serious illness or hospitalization from Covid-19.
“Moderna has said test-tube studies using blood samples from vaccinated people show the vaccine is still highly effective against the Delta variant, which caused only a “modest reduction” in virus-fighting antibodies in the samples. And Johnson & Johnson has released two studies that show its vaccine remains effective against Delta, showing only a small drop in potency.”

Otoh, England will start booster shots in Sep, and intends to poke every living soul over age 49:
