Follow the science: New study confirms natural immunity more effective than vaccines

An age old known reconfirmed

In a new paper just published in “The Lancet’, titled Past SARS-CoV-2 infection protection against re-infection: a systematic review and meta-analysis, found that natural immunity after contracting Covid-19 has better efficacy than Covid-19 vaccines. The principle of natural immunity was disputed in the media and by international health authorities during the pandemic, even though this has been accepted in immunology for centuries.

Natural immunity is the general immune protection your body creates against a disease once you’ve been infected with it. Natural immunity varies according to the person and the disease. 

The study found that protection against re-infection was high, with a mean pooled estimate greater than 82% for ancestral, alpha, beta, and delta variants. By comparison, protection by past infection of earlier variants against re-infection by the omicron BA.1 variant was substantially reduced, with a pooled effectiveness of only 45·3% Protection against symptomatic disease mirrored the results for protection against re-infection. The mean pooled protection from re-infection against symptomatic disease was 82% or greater for ancestral, alpha, beta, and delta variants, and was again substantially reduced for the omicron BA.1 variant. Protection against severe disease (hospitalisation or death) was universally high, with mean protection of 78% or greater for ancestral, alpha, beta, delta, and omicron BA.1. The ancestral variant had the lowest pooled estimate, at 78·1% protection against severe disease One study assessed the protection from past omicron BA.1 against sublineages BA.4 and BA.5 with protection of 76·1.

The conclusion of the paper states:

“”Our findings show that immunity from COVID-19 infection confers substantial protection against infection from pre-omicron variants. By comparison, protection against re-infection from the omicron BA.1 variant was substantially reduced and wanes rapidly over time. Protection against severe disease, although based on scarce data, was maintained at a relatively high level up to 1 year after the initial infection for all variants. Our analysis suggests that the level of protection from past infection by variant and over time is at least equivalent if not greater than that provided by two-dose mRNA vaccines.”

This paper sponsored by the Bill and Melinda Gates Foundation, has been reported upon by mainstream media. Previously, medical media claimed that natural immunity waned much faster than vaccine induced immunity, and people after contracting Covid-19, should still have a Covid-19 vaccination. This new paper puts major doubts over that advice, since natural immunity is relatively much higher than vaccine induced immunity, and lasts much longer.
