An Israeli study shows that booster doses should be permanent – for life

Israeli study more than doubles risk of COVID-19 infection 90 days after second dose of Pfizer vaccine
Researchers at Leumit Health Services in Israel and the US National Institutes of Health (NIH) examined people who had been vaccinated with the Pfizer-BioNTech vaccine.
They found that 90 days after taking the second dose, the risk of contracting the virus more than doubled and only continued to rise after six months.
What’s more, the percentage of positive test results for COVID-19 quadrupled from 2.4 percent after at least 90 days to 10.6 percent after at least 150 days.
The finding adds further evidence that while Pfizer vaccines provide protection in the early weeks, booster vaccinations are likely necessary to maintain long-term protection against Covid.
Researchers examined more than 80,000 adults who had been fully vaccinated with the Pfizer-BioNTech vaccine.
