Eight-week gap between first and second Pfizer vaccine doses ‘a sweet spot’

An eight-week gap between the first and second doses of the Pfizer/BioNTech Covid-19 vaccine is a “sweet spot” when it comes to generating strong immune response while protecting the UK population against the Delta variant of coronavirus, scientists have said.
In a new study, funded by the Department of Health and Social Care (DHSC), researchers have found that when compared to a four-week gap, a 10-week interval between the doses produces higher antibody levels, as well as a higher proportion of a group of infection-fighting cells in the body known as “helper” T cells.

Leaving eight weeks between your first and second dose of the Pfizer Covid-19 vaccine is the optimum gap for immunity and protection, say scientists.
A new study, funded by the Department of Health and Social Care has found that a 10-week gap between doses produces higher antibody levels, as well as a higher proportion of infection-fighting T cells, compared to just four weeks.

However, scientists involved in the study have described an eight-week dosing interval as the “sweet spot” when it comes to generating a strong immune response while also protecting the UK population against the Delta variant of coronavirus – to which people can still be vulnerable after just one jab.
