As a rule, I stay away from any medications as far as I can.
As for vaccines, I'm in favour of them, if it is shown that they are demonstrably safe and effective. A typical vaccine takes 5-15 years to bring to market, and even then they are not rigourously tested.
If you can find a vaccine that has been subjected to the industry standard for medications, that is the double-blind placibo test...let me know. As the vaccine industry is protected from being sued, they don't seem to bother with such tests.
If a CV vaccine was introduced (sorry, that should be when it's introduced) ...ask yourself if you want to be a guinea pig. Also ask why Bill Gates states that the manufacturers will need to be indemnified before rolling out a program. They already are, but he seems to want to stress that. Also ask why every group and entity saying that a vaccine will be necessary, is founded to some degree by Bill Gates, who's wealth has doubles since he started his 'philantropy'.
