Where is the scientific data proving that vaccines are safe for people with Down syndrome?

The CDC admitted in Federal Court[1], in a lawsuit filed by the Institute for Autism Science and ICAN, that they have no evidence that vaccines don’t cause autism. This same regulatory agency has now recommended[2] the Covid19 vaccine for people with Down syndrome, who have a higher risk for autism. This is a shocking recommendation considering that animal trials were omitted to fast track this vaccine to the public. 

Down syndrome is considered one of the most challenging disorders to simulate in laboratory animals. Early attempts at modeling Down syndrome in mice (1974) failed because they died at birth, but in 1990 the Davisson discovery of the Ts65Dnmouse model was somewhat successful and has been used since then to begin to understand this complex disorder.  However, on June 29, 2020 John Hopkins University announced a new mouse replica of DS (TcMAC21)which was reported to eLife Sciences. This new mouse model, using mouse artificial chromosome vectors(MACs)[6], is capable of transferring a nearly complete intact copy of HSA21q and 93% of the protein coding genes (PCGs); meaning that this new humanized mouse is the most complete genetic mouse model for Down Syndrome to date. Researchers have said that mouse models have been critical to understanding of the molecular genetics of DS. The synteny between human and mouse genomes have allowed researchers to pinpoint the genes responsible for the identification of Down syndrome. (This is simply to identify them, not understand how they work), but researchers also admit that “there is no perfect animal model for a human genetic disease, less-so for a complex syndrome’.

Without animal testing to determine if the Covid19 vaccine safe for complex immune system of DS, they have no evidence that this vaccine will be preventative, or if it will be genocide.
