A new CDC study looked at 2,500 pregnant women who got the mRNA vaccine and found no increased risk of miscarriage. Now, the CDC is strengthening its recommendation and urging all pregnant women to get protected as the delta variant surges. Debra Guinn, MD, associate professor of obstetrics and gynecology and vice chair of research at the College of Medicine – Tucson, studies the impact of COVID-19 on pregnant women. Dr. Guinn said her research backs up the CDC's findings. "There is no evidence it causes infertility or miscarriage. The vaccine is safe. There are no apparent negative impacts on pregnancy," Dr. Guinn said.

A parent can legally ask individual teachers if they’re vaccinated, but the teacher doesn’t have to answer, said a recent advisory in Education Week, a journal of K-12 education news. “Anyone can refuse to answer the question, but they should be prepared to be treated as if they are unvaccinated,” wrote Sarah Whitley Coles, MD, a family physician and assistant professor at the College of Medicine – Phoenix, in Dear Pandemic, a website and newsletter that offers family-friendly medical advice.
