Stop calling Omicron "mild".
It is NOT. In fact it is a major public threat and here is why: Allow me please,
Omicron is more infectious than Delta by a factor of 2.7-3.7.
If you are recovered from previous infection, chance of reinfection w/ Omicron is 5.4 times that of Delta

Researchers at UKHSA and NHS estimate the growth and immune escape of the Omicron variant in England.
They used data from for all PCR-confirmed SARS-CoV-2 cases in England who had taken a COVID test between November 29th and December 11th 2021.
They tested for Omicron..

They tested for Omicron..
They separated all non-Omicron case.
They use S-Gene Target Failure or genotyping as Omicron ID signals.
They found the proportion of Omicron among all COVID cases was doubling every 2 days up to December 11th.
Positive patients reported disease severity (how bad they felt)

They controlled for vaccine status, age, sex, ethnicity, asymptomatic status, region and specimen date, Omicron was associated with a 5.40 (95% CI: 4.38-6.63) fold higher risk of reinfection compared with Delta.
That's 5.4 times likely to get reinfected w/Omicron Vs. Delta

Let us put this in perspective: Incredible infectivity!
The UK “SIREN” study of COVID infection in healthcare workers estimated that prior infection afforded 85% protection against a second COVID infection over 6 months.
Reinfection protection from prior infection dropped!
The UK “SIREN” study of COVID infection in healthcare workers estimated that prior infection afforded 85% protection against a second COVID infection over 6 months.
Reinfection protection from prior infection dropped!
The reinfection risk estimated in the current study suggests this protection has fallen to 19% (95%CI: 0-27%) against an Omicron infection.
That means this: If you've had a prior infection and thought that afforded you a protection level, then you are mistaken.

What about Vaccine effectiveness against Omicron?
vaccine effectiveness estimates against symptomatic Omicron infection up to 20% after two doses, and up to 80% after a booster dose.
This means Omicron found a way to EVADE OUR ACQUIRED IMMUNITY.

Therefore, based on this study it is clear to me that
2 vax doses or PI (prior Infection) is not good enough.
You need the booster.
Those who follow me know I've been highlighting Omicron's ability to evade our immunity and that we need an OSV plus continued modified booster

Prof Neil Ferguson said: “This study provides further evidence of the very substantial extent to which Omicron can evade prior immunity given by both infection or vaccination. This level of immune evasion means that Omicron poses a major, imminent threat to public health.”
Conclusion:
1. people must get the booster to optimize their protection against Omicron.
2. Omicron poses a major, imminent threat to public health.
3. Omicron is NOT mild. In fact it is scary as I see it because the next Omicron variant will likely evade our immunity even more
