On a vaccine:
I see people putting a lot of hope in a vaccine. I would caution against that. By the time a vaccine is actually developed, there is probably going to be a fair amount of herd immunity to COVID-19 and a vaccine may not even be warranted. But even if a vaccine is warranted there are other issues: Immunity to coronaviruses does not typically last very long, may be 2 to 3 years on average. The reason we do not have vaccines for other coronaviruses is twofold: one is because they do not cause significant mortality and the other is because a vaccine is unlikely to create immunity that would last for more than 2 to 3 years. I also do not expect to see a seasonal COVID-19 vaccine because COVID-19 outbreaks are likely to become sporadic rather than seasonal like the flu and COVID-19 doesn't seasonally mutate like the flu. Lastly, the population who would benefit most from a coronavirus vaccine are the elderly and immune suppressed, and unfortunately, elderly and immune suppressed people are the ones that respond poorest to a vaccine. On a more positive note, if a vaccine is going to be developed we certainly have the best and brightest working on it. I am hopeful that this will happen. If it does, we need to encourage everyone including the young and healthy to get it in order for it to have the best chance of success.
On a treatment:
Sorry to be a Debbie-downer, but I have similar pessimism about a treatment. We have been trying to come up with a treatment for the other coronaviruses that cause the common cold for many years. All we have to show for it is Vicks vapor rub and NyQuil. I would love more than anything for a proven treatment to be developed and hopefully it is, but I am also not holding my breath on this one either.
Isn't COVID-19 just a bad cold like the other coronaviruses or the flu?:
Hell no! COVID-19 is way worse than other coronaviruses because it has a protein structure that allows it to bind to and invade respiratory epithelial cells much more effectively than its predecessors. As Red mentioned above, it is super contagious - much more contagious than MERS or SARS. The mortality rate of COVID-19 speaks for itself. Of note, the mortality rate that does not speak for itself is influenza. The number of influenza-caused deaths in this country, and therefore the mortality rate, are likely much lower than the CDC estimates. I am not some sort of weird conspiracy theorist, but I have read on its own website in detail how the CDC makes this calculation and I think it is poorly-contrived at best. They do not actually use death certificates, but they have weird formulas that make a lot of assumptions about who may have had flu and who may have died from it. I will spare you any additional comments on that but bottom line is that the flu deaths are a gross underestimate. Think about it. How many celebrities or prominent figures have you already heard of that have died of COVID-19? Now, how many have you heard of that have died of influenza this season? COVID-19 isn't just a little bit more deadly than the flu, it's way more deadly than the flu especially in the elderly and chronically ill.
