People who have previously had the novel coronavirus and have received one dose of a vaccine showed antibody levels comparable or better than those who had received two doses but have never had the virus, a new study found.
The study consisted of 109 vaccine recipients, 41 of whom have had the coronavirus, CNN reported. People previously infected with the coronavirus exhibited general side effects such as fatigue, fever and muscle pain like other individuals might show after a second dose of an mRNA vaccine, the study’s researchers said.
The researchers indicated a “relatively low” antibody response in nine to 12 days after inoculation, CNN reported.
The study reported previous infections swiftly developed high antibody titers “within days,” which measured to be 10 to 20 times higher during some intervals, CNN reported.
The Centers for Disease Control and Prevention as well as Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases and chief medical adviser to President Biden, advise people to get the vaccines even if they have had the virus, given the ambiguity of the duration of antibody protection.
