News Ontario extends time between Pfizer vaccine doses for non-residents of LTC and retirement homes SHARE ON: Mohamed Fahim, staff Tuesday, Jan. 19th, 2021 (Supplied by Pixabay) Everyone who received a COVID-19 vaccine that doesn’t live in a long-term care home or a high-risk retirement residence has to wait for their second dose. Ontario’s Associate Medical Officer of Health has extended the time to 42 days instead of 21 days. Residents of long term care and retirement residences will still receive their second round of vaccinations in three weeks. Everyone else will get the second shot in 42 days. The decision comes in an effort to reserve the Pfizer vaccine for sites that need the inventory to provide second doses. The province will also be reallocating Moderna doses to more areas with no changes announced to the time between its doses.
