Harvard Study: Natural Immunity 27% More Effective Against Delta Variant Than Vaccines

CAMBRIDGE, MA – A recently published Harvard study has found that natural immunity is, in fact, more effective against COVID-19 delta variant than a vaccine.

The study showed that people who are vaccinated are 27 times more likely to get a COVID infection that is symptomatic than someone who has developed natural immunity.

Harvard Medical School biostatistician and epidemiologist professor Martin Kulldorff said that this information points to vaccine passports being unscientific as well as discriminatory.

“Prior COVID disease (many working class),” Kulldorff said on Twitter, “provides better immunity than vaccines (many professionals), so vaccine mandates are not only scientific nonsense, they are also discriminatory and unethical.”

In Israel, vaccinated individuals had 27 times higher risk of symptomatic COVID infection compared to those with natural immunity from prior COVID disease [95%CI:13-57, adjusted for time of vaccine/disease]. No COVID deaths in either group.https://t.co/hopImCD1D0

On Thursday, the Scientific American reported, “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, according to a large Israeli study that some scientists wish came with a ‘Don’t try this at home’ label. – READ MORE
