VACCINE DISCRIMINATION: We need to stop vaccine requirements for US entry like almost every other country. Am finishing COVID chapter for our ID "bible" & vaccines prevented transmission early on with alpha, but not enough now with current variants to justify such discrimination
Moreover, shame, stigma, blame (remember COVIDiots?), coercion, discrimination not good public health tools. When used for HIV, public health & ID physicians decried them but tactics used a lot in COVID. This book tries to explore & correct that for future barnesandnoble.com/w/endemic-moni…
Concept of #harmreduction in pandemic responses means watching carefully if vulnerable people (like students, older people, low-income populations, migrants, sex workers, prisoners, those with disabilities, refugees, minorities) harmed more by response nature.com/articles/s4146…
Oh sorry to hear the tennis player withdrew as could not come to the US with a vaccine waiver. Very few countries beyond US requiring vaccines to enter country anymore sports.yahoo.com/novak-djokovic…

FEAR: Some media & public health officials concerned Americans aren't fearful of COVID now. But the vaccines & therapeutics DO WORK. If we can't celebrate biomedical advances & imbibe their effectiveness (we have better tools for COVID than flu), what is point of developing?
In HIV medicine, when therapies came out, we didn't say to people- stay fearful; make this the controlling principle of your life. The book #Endemic I wrote (coming out July 11, 2023) hails these biomedical advances & the age we are in to fight pandemics to reassure the world
This is a rather brilliant summary of the issue from @benryanwriter
POPULATION IMMUNITY: Nothing stresses a respiratory pathogen like winter months & this 3rd pandemic winter shows what high population immunity has done to decrease mortality rates from COVID: ourworldindata.org/covid-deaths
Place with the lowest amount of population immunity is China as less natural infection from zero COVID policies and vaccination (and boosting rates in elderly) not as high as desired. World & @WHO very rightly worried about China- need vax & therapeutics
PANORAMIC trial (ongoing) in UK will define use of Paxlovid with high population immunity- latter not there in China; China vulnerable 65 & up vax'd or unvax'd high risk need wide availability of Paxlovid (Pfizer CEO ruling out generic in China troubling) reuters.com/business/healt…)
ADOLESENTS: NIH Study (Stanford study, SF). "School shutdowns, severed social channels, and amplified stress at home and in their communities" during COVID amplified anxiety, depression, and brain aging "reflecting more lasting effects of adversity" nimh.nih.gov/news/research-…
Important piece from @NEJM this week on #harmreduction in pandemic management. Do everything in your power to minimize severe disease but stop interventions which cause harm without decreasing pathogen impact; new era in COVID 2023 w/ immunity/vaccines
A holistic view of public health during a pandemic (consider societal effects of interventions; are they really helping?), can increase trust in public health. I - like most ID MDs on this platform- am concerned about trust & less uptake of other vaccines
ONCE YEARLY? Agree with most on here that 1) yearly vaccination needed but for older & more vulnerable (co-morbidities multiple, immunocompromised); 2) May not able to adapt mRNA vax quickly enough
FDA considers major shift in COVID vaccine strategy npr.org/sections/healt…
to new subvariants (e.g. our last bivalent is against BA4/BA5 but Omicron up to XBB1.5) & not clearly better due to adaptive power of cellular immunity (see thread on B cells) so any boost probably ok. Latter in line with @WHO endemic plan put out on March 30, 2022
Immunity works beautifully. Lancet ID 30 million people UK study shows who is still at risk after 2 doses of vaccine for severe disease (>80, immunocompromised, multiple 5 comorbidities) & needed boost. B cells adapt antibodies they make - B cell thread:
Excess deaths during COVID are very complicated & vary by region & duration/degree of lockdown; this was very true at Ward 86 (our HIV clinic at county hospital); sorry to hear this for the city of San Francisco; very much appreciate hard work of addiction teams at SFGH
Good article-excess mortality in COVID likely neglect other med care: "in countries like Belgium/Sweden [highly vax'd], ratio between excess deaths & COVID deaths 1..net change mortality [from] other diseases/injuries during pandemic period minimal" there thelancet.com/article/S0140-…
In US (like article in SF), excess deaths in young people up from accidents, overdoses, suicides, homicides, and internal causes from neglect of medical care (no, not from the vaccines). Very disruptive time for other services & caused despair bloomberg.com/opinion/articl…
Yes immune system works
-Please see cellular immunity pinned tweet; so many papers! Will post more
-This is 7th human coronavirus; we know how coronaviruses work
-Retroviruses (HIV: start RNA & go to DNA) & coronaviruses (RNA virus) different
-Basic principles of immunology hold
Below simple tutorial I hope is how cellular immunity & immune memory work- there will always be variants that may evade antibodies but we are lucky immune system more than antibodies! T and B cells too for variants; Media, good science reporting please! medscape.com/viewarticle/98…
Cellular immunity (high population immunity from the vaccine, natural infection or hybrid immunity) why hospitalizations not rising MA (& why hospitalizations so linked to vaccine rates with delta & BA1; now high immunity from natural/hybrid too)
