Public Health Sudbury and Districts is following the recommendation from federal officials and extending the time interval for COVID-19 vaccines is now being extended to 16 weeks.
As the Pfizer BioNTech and the Moderna vaccines were being rolled out at the end of 2020, Pfizer said its recommended dosage interval was 21 days while Moderna said its recommended dosage interval was 28 days. because the first two months of real-world effectiveness are showing sustained high levels of protection they are extending the interval between doses as it was shown to be a good strategy.
Dr. Penny Sutcliffe, Public Health Sudbury’s medical officer of health says for certain groups, such as residents of long-term care and retirement homes, Elder Care Lodges and those in assisted living communities for seniors, the original dosing interval will apply.
She adds the change will allow the health unit to provide first doses to more people and the agency will rebook all appointments for second doses that now need to be rescheduled.
Individuals will be informed of their new appointment either through email or phone and do not need to take any actions themselves.
