nb. for those wondering why there’s such a discrepancy for israel’s effectiveness vs delta compared to uk and canada; they had a 3 week gap between vax. since very many americans also had such a short gap, there’s a strong argument for a 3rd booster vs delta. ht dr john campbell

i have heard from @nickcammarata that you can basically walk into a cvs or whatever and ask for a third vax, so if you feel like doing this please try and let me know if it worked in the comments
