Hold on there Sunshine....Canada is not producing any Covid vaccines. FYI Winnie-the-Pooh was based on a real-life bear who lived in the London Zoo, and he got there thanks to a Canadian soldier and veterinarian named Harry Colebourn. If you don't want to accept the truth well then
"Congress can enact a law that makes vaccination against COVID-19 mandatory. The state can invoke its police power to justify this measure, especially in light of the pandemic’s effect on our health care system and the number of cases and deaths," Gatmaytan told Rappler. https://www.rappler.com/newsbreak/e...ne-government-make-covid-19-vaccine-mandatory I don't think we get a choice. But the only one I'd hesitate about is Sputnik 5 right now. The flu virus in it replicates at times. They seem to have a manufacturing problem.
According to some researchers, covid-19 is a genetic descendant of the WWI "Spanish" flu, which evolved among young men in crowded conditions and affected them predominantly.
“So far, there is no scientific evidence available that suggests spike proteins created in our bodies from the COVID-19 vaccines are toxic or damaging our organs,” experts at the Meedan Digital Health Lab (meedan.com/digital-health-lab) said. (here) Research shows that spike proteins (here) remain stuck to the cell surface around the injection site and do not travel to other parts of the body via the bloodstream, they added. The 1% of the vaccine that does reach the bloodstream is destroyed by liver enzymes. https://www.reuters.com/article/factcheck-vaccine-cytotoxic-idUSL2N2O01XP
Influenza (flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus first identified in 2019, and flu is caused by infection with influenza viruses. So, no, it isn't a descendant. https://www.cdc.gov/flu/symptoms/flu-vs-covid19.htm
I just read about this vaccine and nowhere does it say it has anything to do with a flu virus. It is an adenovirus vector-based vaccine and adenoviruses are one of the type of virus that cause common colds (plus some serious multi-organ diseases in those with weak immune systems). I read in Wikipedia that "Both [types of adenovirus used in the vaccine] are modified to remove the E1 gene to prevent replication. Large quantities of both adenoviruses are then produced [in a group of human cells] that have the E1 gene necessary for viral replication. Rarely, [one of the two adenoviruses] can acquire the E1 gene from the [culture] cells, restoring its ability to replicate. [The developer] has set an acceptable limit of 5,000 replicating virus particles per vaccine dose, and quality control documents state that tested batches contain less than 100 replicating virus particles per dose." Obviously, if they are not checking batches properly then replication of the original adenovirus might take place - it would not be too concerning (for most recipients) if that produced a minor common cold but organ failure in the immunocompromised would be a very serious side-effect.
There is no known link between influenza viruses and Coronaviruses BUT many mutations can change one thing into another over a long time period (or a short one if the reproduction rate is very high) ... we, after all, evolved from very simple one-celled life forms. But the first Cornaviruses (they were non-human) were discovered in the late 1920s and that seems a very short time between the flu of 1918/19 for it to have evolved into such a different form. Also, many viruses are around for a long period before they are discovered (as with HIV) and Coronaviruses may have been around way before the 'Spanish' flu pandemic. However, I would be interested to know the source of your information (unless it is from Facebook).
