Following a Freedom of Information Act request from attorney Elizabeth Brehm, the Centers for Disease Control and Prevention has revealed that there are no documented cases of an unvaccinated person who was reinfected with COVID-19 and transmitted the contagious virus to another individual.
In a letter from Roger Andoh, the officer of the Centers for Disease Control and Prevention and Agency for Toxic Substances and Disease Registry (CDC/ATSDR) responded to the attorney's FOIA request made on Sept. 2.
In that letter, Brehm requested "Documents reflecting any documented case of an individual who: (1) never received a COVID-19 vaccine; (2) was infected with COVID-19 once, recovered, and then later became infected again; and (3) transmitted SARS-CoV-2 to another person when reinfected."
Andoh responded that "A search of our records failed to reveal any documents pertaining to your request. The CDC Emergency Operations Center (EOC) conveyed that this information is not collected."
Natural immunity has been questioned as to whether or not it is an effective protectant from COVID-19.
An August study conducted by the CDC stated that those who were unvaccinated were twice as likely to be reinfected as those who received the virus.
Some Israeli studies though have come to a different conclusion, stating that natural immunity offers a greater protection against COVID-19 when looking at the Delta variant.
According to Science, "The natural immune protection that develops after a SARS-CoV-2 infection offers considerably more of a shield against the Delta variant of the pandemic coronavirus than two doses of the Pfizer-BioNTech vaccine."
One Israeli study found that those who received the two-dose vaccine were 13 times more likely to fall ill with the delta variant than those who were naturally immune.
