It took 15 years to create the HPV (Human papilloma vaccine) Gardasil vaccination. The Covid vaccine took only one year! It’s amazing what can be accomplished under pressure with money to spare. This is the article where I grabbed the graphic in the headline.
All the Corona virus vaccines require two doses, except for one. It is the same with the HPV vaccine, 2 doses. Same with the shingles vaccine. One problem is getting people to follow up with the booster dose.
I wonder, will the public be more amenable to getting the Covid vaccine than they are to the yearly flu shot? What are your thoughts?
