I have been getting a lot of questions about Omicron, the new COVID-19 variant of concern. We still have so much to learn, but I thought I would share a quick few updates on what we know – the good, the bad, and the ugly – and what we can do.
The Good:
➡ Science is amazing, and watching teams of experts across the globe share information and resources about the variant so quickly is incredible.
➡ Our tests for COVID look like they work to detect this variant. There are thousands of different tests, so more to come on this, but testing (antigen, PCR, and molecular) continues to be an important way of identifying COVID (including this variant) and slowing the spread.
➡ We are doing much more sequencing now compared to earlier in the pandemic (and Alaska continues to lead the country in sequencing data). This means better monitoring to identify this and other variants.
➡ No cases have yet been identified in Alaska or the US.
➡ We know so much more about COVID, and know that ventilation, distancing and masking work to slow the spread. We can keep using these tools.
➡ Even if vaccines prove to be less effective against this variant, some protection is better than no protection, and more than 68% of the 18+ population in Alaska have received at least one dose of vaccine.
➡ The development of effective COVID vaccines and treatments has happened at an accelerated and impressive pace these past two years. Many great people are now working on understanding this variant and how best to fight it.
The Bad:
➡The early data out of South Africa suggest it is very transmissible as they are starting to see a fourth wave after a long and hard third wave caused by the delta variant.
➡ Early cases were reported in both people who had been previously infected as well as those who had been vaccinated.
➡ We are all tired of COVID, but it’s not tired of us. This new variant will make it harder to slow it down.
The Ugly:
➡ There are a TON of new mutations in this one variant: ones we have seen before and ones we have not. Take a look at this sequencing data - The x-axis is time (from December 2019 onwards), and on the y axis is the number of mutations in the S1 gene relative to the original sequences. Omicron (red in the top right) is totally an outlier. https://nextstrain.org/ncov/gisaid/africa?d=tree&l=scatter&p=full&scatterY=S1_mutations. The S1 gene spike protein is how COVID enters our cells. It is also the target for vaccines and most treatments. What this means is still unknown, but we will continue to follow it closely.
So what to do...
➡ If you have not yet gotten vaccinated, now is a great time to start your vaccine series. If you are 18+ and it has been >6 months since your second dose of mRNA vaccine (Moderna or Pfizer) or 2 months since a J&J vaccine, please get a booster dose as soon as possible for added protection. Even imperfect protection is better than little to no protection.
➡ Take care of your physical and mental health. Get outside, stay connected, and remember we are not powerless over this pandemic. This is a new twist, but we will learn and adapt, and we are stronger when we work together. Be well and stay safe!
