Benefit to vaccine delay
A study, supported by the UK Coronavirus Immunology Consortium, found delaying the second Pfizer vaccine dose to 12 weeks significantly increases antibody responses in older people, reported The Citizen (20 May 2021). Epidemiologist Jo Barnes said from an administrative or epidemiological standpoint, delaying the Pfizer dose interval by three months, as opposed to the initial two weeks, will give the country much-needed time to sort out glitches.
According to Prof of vaccinology, Dr Shabir Ahmed Madhi, a single dose of the Pfizer vaccine will likely induce a robust immune response that will confer reasonable protection against moderate to severe disease. However, failure to ensure that these recipients take the second dose may result in scores of wasted doses.
