Flu vaccine changes each year.
How can science determine long term consequences of any drug?
Have their been any studies on short term consequences of the horse dewormer on humans? Of course not, and some advocate its use.
Ridiculous in the extreme.
Let me explain why the irony of that last sentence is extraordinarily deep.
Flu vaccines are based on technologies that have been used for many decades, and they all went through
years of trials to test for longer term adverse effects. The mRNA vaccines have
never previously been used on broad populations (let alone billions of people), and were given "emergency use authorizations" without having undergone anything like the usual safety testing that other vaccines undergo.
In other words, the two are not
remotely comparable, in terms of understanding their long-terms effects, and possible dangers.
Ivermectin is not only approved for human use, but over
three and a half billion doses have been used by ~300 million people over
30 years, and with an exceptionally good safety record. In 2015, one half of the Nobel Prize in Physiology or Medicine was awarded to William C. Campbell and Satoshi Omura for “their discoveries concerning a novel therapy against infections caused by roundworm parasites” – aka Ivermectin.
In summary, please try not to regurgitate "news" that you find in echo-chambers that are rife with propaganda. Instead, take some time and do some serious research, as it will help you to avoid embarrassing yourself in the future.
