One vaccine dose is perhaps sufficient for COVID-19 survivors

In a single examine of 59 healthcare employees who recovered from COVID-19 and obtained one of many vaccines, antibody ranges after the primary shot have been increased than ranges often seen after two doses in individuals with out a historical past of COVID-19.

In a separate examine, researchers discovered that 41 COVID-19 survivors developed “excessive antibody titers inside days of vaccination,” and people ranges have been 10 to twenty instances increased than in uninfected, unvaccinated volunteers after only one vaccine dose.

“The antibody response to the primary vaccine dose in people with pre-existing immunity is the same as and even exceeds” ranges present in uninfected people after the second vaccine dose, the authors of that paper stated.

“Altering the coverage to offer these people just one dose of vaccine wouldn’t negatively influence on their antibody titers, spare them from pointless ache and liberate many urgently wanted vaccine doses,” they stated.
