transmissible over time...first the "Wild Type", original version, which cloth masks could handle fairly well, especially when N95 or surgical masks were in short supply...then Delta, which cloth masks could still work against...and now Omicron, which is much more transmissible and requires N95/KN95 quality masks...things change...there is no one "Consistent" approach...we have to adapt.
As for Trump and vaccines...I'll repeat again...
>1/11/2020...China releases the genomic sequence for COVID-19
>1/13/2020...Moderna completes their 'design' for an mRNA vaccine...on the same day, Dr. Fauci fast-tracks it into Phase 1 testing...because he's been on top of the technology and has been in constant contact with all vaccine producers...he's the man behind any "Warp Speeding".
>Late Jan, 2020...Trump is briefed on the seriousness of COVID-19 (admitted to by Trump, on tape with Bob Woodward)
>2/28/2020...Trump calls COVID-19 the Democrats' "New Hoax"...
5/15/2020...Operation "Warp Speed" is announced ;-).
All Trump did was sign the checks for government production funds when the vaccines were ready...something he'd be pilloried for if he didn't...oh, and btw, Pfizer's vaccine was independently developed....
Ask yourself...who in their right mind would ever "Down Play" a pandemic like Trump did?
