 The study found that healthcare workers who had been vaccinated with the SARS-CoV-2 vaccine were less likely to be infected with the virus than those who had not been vaccinated. Additionally, the study also found that individuals who had both been vaccinated and had been exposed to the virus through natural infection had higher antibody levels than those who had only been vaccinated. This suggests that the combination of vaccination and natural exposure may offer greater protection from reinfection.
