Rubbish.
Firstly, a vaccine is a prophylactic, medication is for symptomatic treatment once you are sick. You could potentially take invermectin every day for "just in case" but its definitely not scalable nor viable globally for prophylaxis.
Secondly, the virus was genetically modified - that's part of what made it a vaccine.
Thirdly, HEK-293 cells were taken from aborted fetuses obtained legally over 40 years ago and infected with adenovirus, and have been cloned since for use in a wide variety of vaccines and medical research including many other vaccines.
As quoted from the Nebraska Medical Center:
"But it's important to have the full context: Fetal cell lines are not the same as fetal tissue. Fetal cell lines are cells that grow in a laboratory. They descend from cells taken from elective abortions in the 1970s and 1980s. Those individual cells from the 1970s and 1980s have since multiplied into many new cells over the past four or five decades, creating fetal cell lines. Current fetal cell lines are thousands of generations removed from the original fetal tissue.
Vaccine makers may use these fetal cell lines in any of the following three stages of vaccine development:
- Development: Identifying what works
- Confirmation: Making sure it works
- Production: Manufacturing the formula that works"
That tweet and related image above are just sensationalism and nonsense.
