- New Strains Of COVID Could Render Vaccines Completely Useless, And 2 Dangerous New Strains Are Already Spreading
by the official CDC website…:To put this problem into perspective, let’s talk about the flu for a moment. Every year, health authorities come up with a flu vaccine that they think will be effective against the variation or variations of the flu that they believe will be dominant in that particular year. Most people simply assume that a “flu shot” will provide them with complete protection against “the flu”, but that is actually not true at all. In some years the match between the flu vaccine and the variations of the flu that are running around is pretty good, and some years that is definitely not the case. The following comes from
During years when the flu vaccine is not well matched to circulating influenza viruses, it is possible that little or no benefit from flu vaccination may be observed. During years when there is a good match between the flu vaccine and circulating viruses, it is possible to measure substantial benefits from flu vaccination in terms of preventing flu illness and complications. However, even during years when the flu vaccine match is good, the benefits of flu vaccination will vary, depending on various factors like the characteristics of the person being vaccinated, what influenza viruses are circulating that season and even, potentially, which type of flu vaccine was used.
