Covid-19 vaccination offers better and more reliable protection against the SARS-CoV-2 virus than past infection, according to the latest data released by the US Centers for Disease Control and Prevention (CDC).

Based on this research, unvaccinated people who had prior Covid-19 infection are five times as likely to be reinfected compared to those who are vaccinated with the Pfizer-BioNTech or Moderna vaccines.

The team's detailed science report indicated that natural immunity and vaccine-induced immunity lasted for at least six months. However, the two mRNA vaccines were more consistent in their protection and provided a boost in antibodies –  proteins created by the immune system that fight off infection – for people who have had prior infection.
