    My new interview with Freddie Sayers: We’ve had lockdown in country after country. Would you call lockdown in the UK, India, Peru, or the US a success? I don’t see how anyone can look at lockdown and say ‘that was a successful policy’.

    Getting over this drought is one of my highest priorities. To that end, I am directing the Department of Agriculture to perform rain dances each day until the rain returns.

    Getting children back to school safely is one of my highest priorities. To that end, I am immediately directing the Department of Health to institute universal masking for anyone entering our schools.

    University presidents, provosts and deans are rarely important public intellectuals today. Should they focus on management, or be willing to lead on contentious issues with strong articulations, risking actual disagreement? We’d be better off if at least some did the latter. 👇

    For thousands of years, disease pathogens have spread from person to person. Never before have carriers been blamed for infecting the next sick person. That is a very dangerous ideology.

    Of course there are severe trust problems when and both doubt/downplay natural immunity from prior COVID infection. Public health must be honest with the public.

    To falsely claim that some political opponents are vaccine hesitant increases vaccine hesitancy. Public health is more important than scoring political points.

    Right now America is intoxicated on masking 2 year olds outside and inside ('cept when they nap - virus naps too) Soon we will be sober and look at what have we done. It won't age well, I promise.

    Missing school is a lot less damaging to a child’s development than dying in a car accident on the way to school. 🤷‍♂️

    Kids didn't have to go to school in the 19th Century so stop being so hysterical if your kids can't go to school now, announces this public health expert.

    Genuine q for ppl more concerned about schools being closed than covid: are you aware mandatory schooling is barely a century old in this country? Maybe ur all grandparents had highschool, but what about ur great-grandparents? Yes, education is important. But it’s a pandemic!

    Multiple studies show that those previously infected have robust, durable immunity w/ extremely low rates of re-infection. Trust in media & public health institutions is being undermined. We cannot "reach people" w/ lies.

    Immunity from the vaccine is better than immunity from getting Covid-19 reports

    Enormous numbers of unvaccinated hospital staff are being fired & college students are being disenrolled. We’re going to lose unvaccinated military, firefighters, teachers & many more ~50% could be avoided if the CDC followed the science & accepted natural immunity! A disgrace
