Please send us corrections, updates, or comments. Vaccines and treatments are both extremely valuable and complementary. All
practical, effective, and safe means should be used. Elimination of COVID-19
is a race against viral evolution. No treatment, vaccine, or intervention is
100% available and effective for all current and future variants. Denying the
efficacy of any method increases the risk of COVID-19 becoming endemic; and
increases mortality, morbidity, and collateral damage. We do not provide

who can provide personalized advice and details of risks and benefits based
