Evusheld monoclonal antibody injections and the COVID-19 vaccines (Moderna, Pfizer or J&J) are not alternatives to each other. While the vaccines help YOU create antibodies against COVID-19, Evusheld actually adds/supplements COVID-19 antibodies. This is especially vital for those of us who might not (or won’t) be able to produce sufficient antibodies on our own. As advised by my doctor. I received the 4 vaccine doses (3 full strength and 1 booster). 2 weeks after my booster, I received the Evusheld injections. Then, a month later, a 2nd dose of Evusheld injections. My doctor still recommends that I should get a 2nd booster vaccination later this year. In case of doubt, talk to your doctor.
