Science Previous Covid Prevents Delta Infection Better Than Pfizer Shot - "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 [from Covid]"

  • Early data from Israel shows natural immunity wanes with time
  • People who recovered from Covid may face lower risk from delta

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 SE.

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.


The analysis also showed that protection from an earlier infection wanes with time. The risk of a vaccine-breakthrough delta case was 13-fold higher than the risk of developing a second infection when the original illness occurred during January or February 2021. That’s significantly more than the risk for people who were ill earlier in the outbreak.

Giving a single shot of the vaccine to those who had been previously infected also appeared to boost their protection. The long-term benefit of a booster dose of the inoculation, which has just recently begun in Israel, is unknown.

The data was posted as a preprint article on medRxiv, and hasn’t yet been reviewed by other researchers.

I had the previous variant of COVID just a few weeks ago.
Ver archivo adjunto 2488968
I had Covid Classic in Feb 2020 while people were still tarding out about "nooo you can't ban china citizen from coming here that's racism!" and no one was aware that it had already been spreading. They don't make 'em like they used to.
 
Get on my level, December 2019. I had it before the masses knew covid was a thing.
I was there for the threads on /pol/ talking about the Wuping Cough in late November and December of 2019, even remember all the anons talking about getting n95 masks and vitamin C supplements. Weird how its basically been ahead of the curve for the most part, so long as you filter out the noise.

What was weird for those times, was I was out of commission for 3 weeks, and the doctors where talking about how this new illness they where calling the "Canadian flu" at the time was floating about but they weren't reporting it in the news so it wouldn't cause a panic.

I mean obviously, had they not waited it would've damaged the Corporate profits of holiday season 2019 and had a vaccine already in distribution before the election. Same reason why certain subordinates deliberately misled the President as to the status of the draw downs of troops in order to prevent them from actually leaving while Trump was in office.
