Covid Vaccines: The Good, The Bad, The Ugly
'The Israeli data shown indicates that the effectiveness against infection reaches levels close to zero after about half a year ..... covid vaccines do not achieve mucosal immunity (unlike natural infection)'
Souce
The Israeli data shown above indicates that effectiveness against infection and mild symptoms decreases rapidly over time and reaches near-zero levels after about half a year. Most likely, this is because covid vaccines do not achieve mucosal immunity (in contrast to natural infection) and serum antibody levels (i.e. antibodies in the blood) decrease within months (see chart below).Thus, the false promise of very high protection against “symptomatic infection”, found during official vaccine trials, was simply based on very high short-term serum antibody levels mimicking mucosal immunity. The pharmaceutical companies probably even knew that this was just a (very lucrative) “flash in the pan” and not a lasting protective effect.
