Study Shows Natural Immunity Prevents Delta Variant Better Than Pfizer Shot


A new study that was conducted in Israel reveals that those who have been previously  infected with Covid-19 from an earlier wave are less likely to be infected with the Delta variant than those who have been fully vaccinated by a Pfizer vaccine.

Researches from Israel came to the conclusion that  “natural immunity affords longer lasting and stronger protection against infection due to the delta variant”.

It was also reported that those who were given the Pfizer shot were 6x more likely to be infected with the Delta variant those those who have already been previously infected.

The research was published by Bloomberg which is surprising considering every mainstream media news outlet has been pushing the vaccine since day one.


Bloomberg published the research and shared these details:

People who recovered from a bout of Covid-19 during one of the earlier waves of the pandemic appear to have a lower risk of contracting the delta variant than those who got two doses of the vaccine from Pfizer Inc. and BioNTech.

The largest real-world analysis comparing natural immunity — gained from an earlier infection — to the protection provided by one of the most potent vaccines currently in use showed that reinfections were much less common. The paper from researchers in Israel contrasts with earlier studies, which showed that immunizations offered better protection than an earlier infection, though those studies were not of the delta variant.

The results are good news for patients who already successfully battled Covid-19, but show the challenge of relying exclusively on immunizations to move past the pandemic. People given both doses of the Pfizer-BioNTech vaccine were almost six-fold more likely to contract a delta infection and seven-fold more likely to have symptomatic disease than those who recovered.

“This analysis demonstrated that natural immunity affords longer lasting and stronger protection against infection, symptomatic disease and hospitalization due to the delta variant,” the researchers said.


Business Insider reported data from the University of Oxford:

Fully-vaccinated people who have previously caught COVID-19 are the group best protected against the highly infectious Delta variant, real-world UK data suggests.

The study added to the growing body of evidence that COVID-19 vaccines offer good protection against Delta after two doses, albeit slightly less protection than against Alpha, the formerly dominant coronavirus variant.

The study, led by Oxford University, the UK Office for National Statistics, and the UK health department, found that getting two COVID-19 vaccine doses was the “most effective way” to prevent infections caused by the Delta variant.

Protection against infection was higher when people had previously caught COVID-19, the study authors said in a preprint posted Thursday.
