How Much Time To Leave Between Your Two Pfizer Vaccine Doses


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.
