RE: Coronavirus - is enough being done to contain it?

the figure you are quoting is not proven at all and in fact in the latest study to come out of SA published 2 days ago they found that 2 dose of pfizer is up to 70% effective against Omicron not the 90-95% against delta but still very good i think, and early data shows that a booster gets that back up to 90%,
its also worth pointing out that the figure you quote is about the most server of illness which will only happen in a very small % of people the same report says that the % of effectiveness at stopping people being hospitalised is likely to be much higher,
for me it again shows that we should be putting our trust in getting jabbed and not in covering faces with a bit of cotton,

RE: Coronavirus - is enough being done to contain it?
Billy Gardner and Marm Kilpatrick from the University of California, Santa Cruz developed computer models incorporating data on COVID-19 vaccines' efficacy against earlier variants and initial data on the Pfizer (PFE.N)/BioNTech vaccine against Omicron. Their models suggest that early after two doses of an mRNA vaccine from Pfizer/BioNTech or Moderna (MRNA.O), efficacy against symptomatic infection from Omicron is only about 30%, down from about 87% versus Delta, they reported on Sunday on medRxiv ahead of peer review. Protection against symptomatic infection is "essentially eliminated" for individuals vaccinated more than four months earlier. Boosters restore protection to about 48%, "which is similar to the protection of individuals with waned immunity against the Delta variant (43%)," Kilpatrick said.
"Importantly, protection against severe disease is much higher" for all categories: recently vaccinated, waned, or boosted. "We estimated that protection against severe disease was 86% for recent mRNA vaccination against Omicron, 67% for waned immunity, and 91% following 3rd dose boosters," Kilpatrick said. "There are still no direct estimates of vaccine effectiveness for severe disease from any country yet, so our estimates cannot be compared to direct estimates yet."
If you had your vaccine 4 months ago you have zero protection against Omricon ?????
