As the one shot is probably sufficient, as there is some level of antibodies against the virus exist in people who were already infected and with one shot, they basically develop the level of antibodies that most people get with two shots of vaccine;b] Is the infection has primed the immune system and the on shot vaccine is effectively boosting those existing immune responses? This concept is also supported by a new trial on Moderna' vaccine, using the same vaccination principle, than the Pfizer vaccine, indicating that that a single dose is effective after 2 months of vaccination. However, in support of the UK decision it should be mentioned that the one dose of Pfizer/BioNTech's COVID-19 vaccine is 51% effective at preventing both symptomatic and asymptomatic SARS-CoV-2 infection and this level of efficacy meets the WHO acceptance criteria for the useful vaccine to be equal or over 50% efficacy.
