Umbilical cord blood is full of stem cells, so it can be transplanted into patients to treat certain types of cancers, diseases and blood disorders. Umbilical cord blood works as an alternative for many patients who can’t find bone marrow transplants. But the odds that someone will develop a disease like cancer that would require an umbilical cord blood transplant are slim, about one in 1,000 or one in 2,000, according to University of Arizona umbilical cord blood stem cell researcher David Harris in the Department of Immunobiology at the College of Medicine - Tucson.

According to Arizona's COVID-19 vaccination plan, teachers in Arizona, along with health care workers, will be among the first group of people to get the vaccine. "Schools should be the last thing to close, and they should be the first to reopen, and that should be the priority. I think we should be offering teachers the vaccine and including them as part of the first-line health care workers. Education and mental health are very important to children, and it is just as important as the physical health of our population," said Dr. Shad Marvasti, director of public health, prevention and health promotion with the University of Arizona College of Medicine – Phoenix.

Dr. Farshad Fani Marvasti, a public health expert, physician and associate professor at the University of Arizona College of Medicine Phoenix, said sporting events need to be banned statewide until the spread of COVID-19 is under control.

Dr. Shad Marvasti, director of public health, prevention and health promotion with the University of Arizona College of Medicine – Phoenix, said that news of a vaccine is cause for optimism – but he cautions that much of 2021 will still require social distancing and mask wearing. "Hopefully if we do that, if we can be strong in this resolve, then we can get back to some kind of normal life post-vaccination, later I would say in 2021," Marvasti said. "Realistically, the majority of people aren't going to have access to this vaccine until late spring or early summer."
