After getting just one shot of a Covid-19 vaccine, people who were previously infected showed antibody levels equal to or above those of people who had gotten both doses but never been infected, according to a study published Monday.

After getting just one shot of a Covid-19 vaccine, people who were previously infected showed antibody levels equal to or above those of people who had gotten both doses but never been infected, according to a study published Monday.

How the research was conducted: The study involved 109 vaccine recipients, 41 of whom were previously infected with the virus.

The study does not specify which vaccine participants received or how severe their illness was when they were infected with the virus.

People who had not been infected before showed a "relatively low” antibody response in the first nine to 12 days after vaccination, researchers said.

The US Centers for Disease Control and Prevention says that people should get vaccinated even if they had Covid-19, since it’s yet unclear how long antibody protection lasts.

Speaking to CNN's Wolf Blitzer later Monday, Fauci said even if someone has had coronavirus, there's a "very high rate" of being reinfected with the new variants if they become dominant.

"If it becomes dominant, the experience of our colleagues in South Africa indicate that even if you've been infected with the original virus that there is a very high rate of reinfection to the point where previous infection does not seem to protect you against reinfection," Fauci said on CNN.

If she'd waited to get vaccinated until it was her "tier's" turn, Isabela Medina wouldn't have gotten the Covid-19 vaccine until late summer.

These vaccine seekers, spurred by reports of doses being dumped and feeling antsy for the country's vaccine rollout to pick up the pace, say they want to prevent waste -- by getting their shot early.
