Mrs. Calleja seems a poor attorney, and a worse scientist. 

If she had scientific knowledge, she would understand the unhelpful, if not detrimental effect of widespread use of a therapeutic like the COVID-19 MRNA injections within a juvenile population. Therapeutics that treat, but do not sterilize patients to an infectious pathogen fail to provide herd immunity, which is why we do not recommend giving all children mandatory antibiotics. Doing so only "educates" microbes and encourages their mutation to a form we do not have a therapeutic for. The COVID-19 injections are recommended to the old and infirm first for a reason.  Most people can understand why profligate prescription of antibiotics to children causes problems for elderly patients when bacteria become "resistant" to available antibiotics. This is no different.

If Mrs. Calleja knew the law, she would know that her daughter's convenience in attending school does not constitute a compelling governmental interest that would supersede the constitutionally-protected rights of the rest of Virginians, which is the basis for religious exemptions.   

If she knew the law of Virginia or some of its history in the Hampton Roads area, she might have read about the story of Abraham Cherrix, and the last time that governmental overreach intruding upon a family's medical decision-making met its match in the Old Dominion. I was a young attorney at the time, but I worked on briefs that vindicated parental rights against an out-of-touch bureaucrat. When the teenaged Abraham declined a doubly-aggressive treatment after a first round had failed, a temporarily-appointed J&DR judge ordered the Cherrix family to present him for treatment less than a week later. That order was countermanded at the Circuit Court, and a reasonable accommodation was reached.

What is evident is that Mrs. Calleja is politically-motivated to impose her preferences on her fellow Virginians. Despite working for the Office of the Attorney General, Mrs. Calleja appears to have an active Twitter profile, with a decided political bent that is unbecoming a public servant: twitter.com/kristencalleja. I would like to voice my request that her office will mandate that she tend to her own business and learn some humility and propriety.

Disclosure: I am a Virginia-licensed attorney, and over the last decade, I have represented approximately 200 people injured by vaccinations within the National Vaccine Injury Compensation Program at the United States Court of Federal Claims.
