Unfortunately, I cannot create a summary of the requested article because the article titled "Texas Probe Targets Pediatricians, Alleges Illegal Vaccination 'Scheme'" from MedPage Today is not found in the search results provided. The search results contain information about other investigations by Texas Attorney General Ken Paxton regarding covid vaccines and other topics, but not the specific article you requested to be summarized. In order to create an accurate and factual summary, I would need access to the full text of this particular article. If you have an article available, you can provide it to me and I will be happy to summarize it according to your requirements.
