With working vaccines its the matter of when not if. What makes you think otherwise?

if new variants escape inoculation by the vaccine, and keep coming about faster than new vaccines can be produced and administered.

> if new variants escape inoculation by the vaccine

Do they? I've looked for information on this, but haven't found it. Do existing vaccines protect against the new variant from the UK?

> Contracting COVID-19 may lead to long term health issues. Uh-huh. And what percentage of people who contract have "long term health issues"? This is just more scaremongering based on self-reporting and anecdotes.

/sigh 30 seconds of Googling and you can find this from the BMJ “Around 10% of patients who have tested positive for SARS-CoV-2 virus remain unwell beyond three weeks, and a smaller proportion for months (see box [1]).[7] This is based on the UK COVID Symptom Study, in which people enter their ongoing symptoms on a smartphone app. This percentage is lower than that cited in many published observational studies,[8][9]…

Only 10% of people with positive test results have "long term" health effects >= 3 weeks? Does that seem frighteningly out of the ordinary compared to other diseases?

When I had the flu or pneumonia in the past I could still feel effects over a month later.

"Wet markets" are just farmers' markets.

... that sell wild caught animals, and usually don’t have a domesticated counterpart.

A large proportion of these "wild" animals are actually farmed.

There's a difference between being exposed to dirt and being exposed to viral diseases, though. Playing outside in the leaves will likely trigger healthy immune responses. Contracting COVID-19 may lead to long term health issues.

This was just reported today.

> Researchers don’t understand exactly how the disease might trigger Type 1 or Type 2 diabetes, or whether the cases are temporary or permanent. But 14 percent of those with severe covid-19 developed a form of the disorder, one analysis found.

It's interesting to me that urban living would be included in the hygiene hypothesis. Intuitively, I would expect all the extra contact and travel to increase exposure to microbes, compared to "everyone spends most of their time on their own farm".

Different kind of microbes. Human communicable diseases in cities, dirt microbes in farms.

Someone put forth the example of polio. It was endemic but not epidemic till the rise of cities facilitated transmission.

So far they believe all the know strains are still covered. Nobody knows if that will continue to be the case. The MRNA vaccines are targeting the spike protein, which is what gives it many of it's infectious properties. If it does mutate to change or eliminate that spike, we might get lucky and those strains won't be as serious, but nobody can predict the future.

>Have you heard of any coronavirus variants coming out of South Korea, China, or New Zealand? No. That’s because they don’t have uncontrolled spread there, which leads to mutations due to the virus’s exposure to heterogenous immunity in the population. That's one hypothesis. Don't particular populations already have a degree of natural herd immunity to viruses which are commonly found in their proximity, compared to…

The term you’re looking for is cross-reactivity and it’s possible that populations have some cross reactivity to COVID. In fact, I’ve heard a hypothesis that the pandemic of 1890 was the predecessor of one of the common cold coronaviruses. Regardless, New Zealand is clearly not an Asian country.

Cross-reactivity! Thanks, TIL.

New Zealand is obviously a bit of a red herring considering it is an affluent island nation with a low population density.

On the other hand I’ve heard conjecture that exposure to other milder corona family viruses has given people some protection from COVID.

Right, I mentioned cross-reactivity in another comment. A term to google for if you’re interested.
