People previously infected with the novel coronavirus responded very strongly to one dose of the Pfizer vaccine, regardless of when they were infected and whether or not they had detectable antibodies against Covid-19 prior to receiving the vaccine, a new study suggests.

According to the researchers, the strong response to one dose of the vaccine among those previously infected regardless of the duration between infection and vaccination is good news.

"This finding can help countries make informed decisions regarding vaccine policy -- for instance, whether those previously infected should be vaccinated on priority and, if so, with how many doses," said researcher Michael Edelstein from the Bar-Ilan University.

"It also offers reassurance that not having detectable antibodies after being infected does not necessarily mean that protection following infection is lost," Edelstein added.
