Israeli study finds natural immunity superior to vaccination
If the findings are confirmed, the implications for Covid policy will be profound…
A major study conducted by Israeli researchers into natural immunity has found that immunity acquired via infection from Covid-19 is superior to immunity from the Pfizer vaccine.
Researchers at Maccabi Healthcare and Tel Aviv University compared the outcomes of over 76,000 Israelis in three groups: the doubly vaccinated (with the Pfizer vaccine), the previously infected but unvaccinated, and the previously infected with only a single vaccine dose.
They found that fully vaccinated but uninfected people were significantly more likely to have a “breakthrough” Covid infection than people who had previously been infected and recovered from the disease.
“This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalisation caused by the Delta variant,” the authors conclude.
