The letter from Centner Academy, read in part, "...if you are considering the vaccine for your Centner Academy student(s), we ask that you hold off until the Summer when there will be time for the potential transmission or shedding onto others to decrease," WSVN reported.

"Because of the potential impact on other students and our school community, vaccinated students will need to stay at home for 30 days post-vaccination for each dose and booster they receive and may return to school after 30 days as long as the student is healthy and symptom-free," the letter added, according to WSVN's reporting.

The school had previously made unsubstantiated claims about adverse reactions non-vaccinated people could have by "interacting with people who have been vaccinated" that have not been identified in or supported by research by the Centers for Disease Control, Food and Drug Administration, National Institutes of Health or World Health Organization.

All four agencies, backed by extensive research, have confirmed that vaccines are the best method of defense against the spread of the coronavirus and severe illness and death from Covid-19.

The vaccines are being studied in younger ages.

Teachers warned in April

In April the Centner Academy asked its employees to wait until the end of the school year to get vaccinated, but still cautioned that if they did, they wouldn't be allowed to return for the next academic year.

The school's CEO and co-founder, Leila Centner, sent a letter to faculty and staff at the Centner Academy citing unsupported assertions about Covid-19 vaccines that contradicted a large body of evidence of the vaccines' safety and efficacy from health experts.
