A new study has revealed that a longer gap between first and second doses of the Pfizer-BioNTech COVID-19 vaccine makes the body's immune system stronger. The study looked at more than 500 healthcare workers and compared groups that had a gap of about three weeks and ten weeks between injections. The findings suggested that both short and long dosing intervals of the Pfizer vaccine generated strong immune responses overall. Real-world data from Public Health England show the Pfizer vaccine is effective at reducing levels of serious disease, hospital admissions, and death, even after one dose. The Pfizer jab is one of three currently being used in the UK, along with vaccines made by Oxford-AstraZeneca and Moderna.
