Medscape is very legitimate. You just don't like what they have to say here.
If you have read medscape articles...you'd know that it's incredibly professional and essentially all of their COVID related articles recently have been very favorable toward the vaccine. Heck...read their front page. Here are their headlines: "J&J Booster Reduces Hospitalizations in South Africa, Studies Show", "COVID Vaccine Rarely Lead to Serious Problems in Ages 5-11: CDC". You'd actually have to look REALLY hard to find something remotely anti-vaccine.
