update 4 feb 2021 -johnson and johnson announces it may have one shot vaccine storable normal refrigeration- us supply by summer
update china's 2 vaccines sinopharm, sinovac - rated between 50%-75% in stopping infection but 90+% effective in making corona virus more serioys than other flus- they only nee a normal fridge but styill need 2 doses- countries proving their efficacy include uae- who to judge on them by march-
data not fully collected on optimal time interval- 3 months is likely practical; 4-6 weeks hypothesised optimal
vaccines most likely to vaccinate largest number of people
astra zeneca, and may be johnson and johnson -on stable normal temperatorues- astra production partnership through gave massive reionally eg india
china's vaccine and russian sputnik - the west claims these have not been tested formally though population live results will soon be in
the eu has spread likely false claims about astra zeneca suggesting its not effectives for over 60s- this likely misinformation caused by less random testing of elders-again this will coon be proven by real data
generation vaccines likely to vaccinate rich people eg americans- implied as more widely effective but no definitive evidence- complicated by abnormal storage temperatures
pfizer
moderna
for uptodate info look at lancet or new england journal of medecine
major mistakes made
western govs misled that main transfusion by touch/surfaces not shared air droplets- crowded rooms-main but incomplete protection masks
failing to close down international travel early enough to prevent being a covid nations
failure to app tracing data
failure to ai model at all levels from last mile to federal
watch this space more than hudred vaccines in test - some may need to prevent new variants though as of feb 2021 it seems likely variants still work
-in reality, it may be all covid-ending vaccines need annual distribution like flu -however the hope is that dynamics such as herd immunity and full tracing may terminate the disease by 2025 but only if we can reach poor as well as rich nations
