The big pharma funded corporate scientists and media have been telling us that you need to take the vaccines because our Immune systems do not recognize the Covid-19 virus as it is 'novel'. But in fact the SARS Cov 2 virus (covid19 virus) resembles SARS Cov 1 virus (that causes SARS) by 80% to 90%. Now, recent studies have shown that our immune systems recognize Covid-19 virus remarkably well and mount a strong, quick and effective response to the invader. Basics of immune response: Based on immune cells, the immune response can be lymphocyte mediated (for viruses) or neutrophil mediated (for bacteria). Based on the antibodies developed against a pathogen, the immune response could be IgM mediated (for new pathogens) or IgG/IgA mediated (for old pathogens which had already infected us). IgM (immunoglobulin M) mediated response takes weeks (around 4 weeks) to develop while IgG/IgA (recall response Igs) mediated response takes just 3 to 5 days. This is because our immune system
Science progresses by questioning the existing dogmas.
