A health care worker holds a vial of Pfizer s novel coronavirus vaccine at the Tokyo Medical Center in Meguro Ward on Feb. 17. (Pool) HELSINKI Finnish nurse Sari Roos is teaching her colleagues a vaccination technique that enables her to squeeze more doses out of COVID-19 vaccine vials, helping to stretch scarce supplies and ensure more people can be inoculated. Her air-bubble trick makes it possible to extract an elusive seventh dose from vials of the vaccine from Pfizer one more than the six approved by Europe’s health regulator that can normally only be drawn with a special needle and syringe. Such ‘low-dead-space’ shot utensils are in short supply, making Roos’ trick all the more valuable as countries seek to protect people against new, more infectious coronavirus strains that are spreading a third wave of infection.
