Industry News: Longer interval between Pfizer vaccine doses boosts immunity
Researchers found that longer dosing intervals led to higher antibody levels and a higher proportion of ‘helper’ T cells
23 Jul 2021
One of the world’s most in-depth studies into COVID-19 immune response to vaccines shows both short and long dosing schedules of the Pfizer COVID-19 vaccine generate strong antibody and T cell immune responses.
The new preprint study involving University of Liverpool researchers found that after two doses, the longer dosing interval led to higher antibody levels and a higher proportion of ‘helper’ T cells, which support immune memory and antibody response.

A new study published today has highlighted a “30-day window” for hospital inpatients to be vaccinated against COVID-19 to help reduce their risk of dying.
A Cardiff University-led team analysed 2,508 hospital patients across 18 sites during the first wave of the pandemic to assess the impact of being infected with COVID-19 in hospital on risk of death.
They found the risk of dying from COVID-19 was far greater for patients who catch it while already in hospital than it is for those who get the virus in the community, reflecting the vulnerable nature of these individuals.
The findings highlight a month-long window for vaccination between admission to hospital and SARS-CoV-2 infection. The study, the largest of its kind to date, is published today in the BMJ journal Thorax.
