No one yet knows the answer. But scientists are actively looking now.\n\nVaccines first became available in December, but only to front-line health care workers. They became more widely available in March and April. The people in the earliest clinical trials were vaccinated as early as last August. So, we are just beginning to have some 1-year-later-data about how long immunity might last. Stay tuned.\n\nOkay great I'll be watching and thank you!
