“When you say that a disease [has] transitioned from epidemic to endemic, there are no hard and fast rules to determine that. Once COVID-19 loses that ability through enough immunity … I think the world is going to get to endemicity, but it's going to be on different timelines depending upon where you are at. I think that from the very first day in the COVID-19 pandemic, it was always going to be the case that this became an endemic respiratory virus. The main priority was to get more tools, like vaccines, antivirals, and monoclonal antibodies, that would help to reduce the strain on hospitals and health systems. Omicron has accelerated this process … we are basically at the cusp of endemicity and it may be the case that after Omicron surge washes over the countries of the world, we will be clearly in the endemic phase.”

“The lower hospitalization rate is likely due to two things: greater immunity among the public from vaccines and prior coronavirus infection, and that omicron might be slightly less severe than delta. Vaccines don't stop infections with omicron, but they do reduce the risk of hospitalization by about 70% - with a booster shot, that figure is even higher. If you're a person who has no immunity at all, no vaccination and no prior infection or your prior infection was a year and a half ago and it was mild, you're not out of the woods. There is a reasonable chance that you will get very sick with omicron.”

“Even if that immunity is not as good against Omicron, it doesn't mean that it's worthless. And that immunity is more effective against serious illness than it is against getting infected at all.”

“It is also noted that by infecting many more people, a very infectious virus may cause more severe disease and death even though the virus itself may be less pathogenic. Therefore, taken together with our recent studies showing that the Omicron variant can partially escape immunity from vaccines and past infection, the overall threat from the Omicron variant is likely to be very significant.”

“We need to achieve the first step - at least a certain percentage of vaccination coverage - before we can start considering reopening national borders. The fewer local COVID-19 cases we have, the weaker our general immunity against COVID-19 is, and our vaccination coverage is at this point lower than that of several other countries, so Taiwan has a relatively weak immunity.”

“The big picture is after the first wave, the great majority of the country didn't have evidence of protective immunity. The need for a vaccine is still very large, the data doesn't change that.”

“We can see the antibodies and we can see them declining and we know antibodies on their own are quite protective. On the balance of evidence, I would say it would look as if immunity declines away at the same rate as antibodies decline away, and that this is an indication of waning immunity.”

“Immunity is waning quite rapidly, we're only three months after our first [round of tests] and we're already showing a 26% decline in antibodies.”
