So refreshing to hear this perspective from abroad. There is heavy pressure in the U.S. to get vaccinated, regardless of age or risk level (not sure whether you feel the same pressure in Switzerland).
I should also add that I have more than half a dozen friends who have experienced some level of non-transient side effects from the vaccine (mostly myocarditis in boys in their 20s and a teenage girl who developed recurring epileptic seizures within 24 hours of vaccination). I’m sure many have been safely vaccinated, but given that I (like you) have antibodies and am otherwise healthy, I’m not interested in rolling the dice with the vaccine.
