Natural immunity provides a stronger immune response than vaccination alone. So, there is a large group of people that have better immunity than any vaccine can give. But, they must still get vaccinated because the president says so? That is some fucked logic.
If all natural immunity people are required to get the vaccine because it gives them better immunity than they already had then by that same logic we should require all vaccinated people to get infected with COVID. Then everybody has the same immunity level.
Infecting someone with a deadly disease is not an ethical medical intervention. Vaccination is.
The requirement isn't to achieve the maximum level of immunity that is possible. It is to achieve the maximum level of immunity that is possible without incurring significant risk.
Natural immunity is better than the vaccine. There is a risk of adverse reactions to the vaccine. You are arguing that people who already have superior immunity take additional risk. This is as unethical as demanding the vaccinated get infected with COVID.
A headache isnt even listed as an adverse reaction. Please base your argument in fact. Getting the vaccine is not risk free and can rarely result in death. The chance of a natural immunity person getting COVID again and dying is lower than a vaccinated person.
