“Ontario was very conservative with following the Pfizer recommendations to the letter and keeping the Pfizer vaccine in a minus 70 containment space which made transport to long-term care very difficult,” said Laura Tamblyn Watts, CEO of CanAge, a national advocacy group for seniors. “Since then however, we have seen excellent evidence that it can be transported and that even one dose can be protective, so it seems that the evidence is allowing us to get the first shots into the arms of people sooner and that the Pfizer vaccine can go to long-term care.”
