Why monoclonal antibodies are not a substitute for COVID-19 vaccines
ABC News
Data supporting antibodies is limited compared to that for authorized vaccines.
Despite more than 187 million Americans being fully vaccinated against COVID-19 and data and attestations from researchers and public health officials that the vaccines are safe an effective, a small and in some cases vocal minority of Americans are reluctant to get the shot.
The reasons vary, but a number of those people are instead turning to treatments after they are diagnosed that have far less evidence to support their safety and effectiveness, including monoclonal antibodies -- a trend that experts say is worrying.
Currently, over 1 million doses of monoclonal antibody infusions have been given in the United States. Use of monoclonal antibodies gained steam during the delta variant surge over the summer when Florida and other states opened clinics to administer the drugs in an attempt to keep sick people out of overwhelmed hospitals.
Monoclonal antibodies have been authorized for post-exposure prophylaxis, meaning they are used shortly after someone tests positive in order to prevent progression to severe disease. The antibodies range in effectiveness depending on type, but some have been shown in to reduce COVID-related hospitalization or death by up to 85%.
