Two studies reporting last weekend went out into cities - one in CA, one in MA - and asked passersby at random to give a blood sample for a survey. The CA survey found 85 times as many people exposed as they expected. The MA group found almost 1/3 of the samples had exposure.

Sweden is taking a risky path. Supposedly, they’re trying to get enough Swedes exposed to develop herd immunity. Problem is, that’s a tactic that works best with vaccines.

Second problem - we don't yet know if natural exposure to the disease actually produces herd immunity for any length of time. For the flu, immunity (from exposure or vaccine) lasts maybe six months. For other coronaviruses, immunity varies. So, this is an extremely risky bet, as they could go through the pain and death and get nothing effective for it.

Wow. That's so weird to me as they don't here (or at least in my part of the States).

With so many other fast food burger competitors? Probably not worth it - burgers will require different equipment in the kitchen just for the burgers...

the reason we lose flu immunity is because the flu virus mutates quite quickly. If it stayed unmutated our immunity would last much longer.

In reading about common cold vaccines the reason we don’t have one is because there are 50 some strains of common cold floating around. Some researchers believe the past attempts at vaccines for it were effective for the particular strain they were vaccinating against and that the problem with creating an effective common cold vaccine is more about logistics than the virus or our immune systems.

One can imagine a doctor telling a parent "Give your child this pill, it's his Common Cold vaccine" and handing over something the size of a granola bar, not a Flintstones Chewable Vitamin.

also, as I read a credible article but can't re-find it, there are zero vaccines for coronaviruses. It's never been done.

And upper respiratory infections are not ideal candidates for vaccines because your lungs are more like an external facing surface akin to (but not the same as) skin than they are an internal organ where vaccines and all that biomumbo-jumbo operate.

Not necessarily. Not by a long shot. That exposure/infection = long immunity is a myth.

Infectious diseases interact with our immune systems in various ways. Not all of them, by a long shot, do so in a way that has use keeping up levels of antibodies that produce immunity for months or years.

Some researchers believe...

Belief is not a measurement. Hope is not a strategy.

First, we have to note that "strain" does not equate to "different immune response". You can have two strains that have the same protein markers for our antibodies to lock onto. So, "50 strains" does not equate to "need 50 vaccines".

However, for sake of argument, let us assume that there are 50 strains we'd have to tackle separately, and they are all out there. If they create lasing immunity, you should be becoming immune to one strain each time you have a cold! In the US, in K-12 schools, on average that's probably a couple strains a year - kids are always getting the sniffles. By the time you are 50, it should be darned near impossible for you to get a cold.

But it isn't. 50-year olds get colds all the time! That everyone can always seem to catch colds suggests rather strongly that there are significant limits to the immunity coronavirus infection grants.

Edit to add: Some folks will note that cornoaviruses aren't even the most common cause of colds. That is correct - rhinoviruses are the more common culprit. However, even with 90+ serotypes of rhinovirus out there, the argument still holds - if we generally generated lasting immunity to a virus, getting a cold should be difficult by they time you are an adult, because we are constantly exposed to these viruses.

Ergo, hoping or planning for herd immunity not generated by a vaccine is not wise at this time.

As I mentioned upthread and Umbran just reiterated, post-exposure coronavirus immunity is very variable, lasting years for some and only months for others. We don’t know yet where Covid-19 falls in the spectrum.
