Dengue fever is much, much worse on the second infection.
This is very sweet (and well done). The kids are singing about âmemories bring back you.â This was recorded last May, 7 months and so long ago.
Dengue fever
Thanks!
Thank you for this. It brought tears to my eyes.
Not necessary. Cell phones work just fine.
I had heard something along those lines on a report several weeks ago, that they didnât know how long immunity would last simply because the trial was ongoing to determine that.
It also in some fashion plays into a ethical debate now underway about whether to give all the placebo recipients the approved vaccine now, as a group, essentially ending the trial. I gathered that the thinking is to give trial volunteers who received the placebo the vaccine quickly, knowing it will limit additional insights that might otherwise have been gained, which probably includes some measure of how effective the vaccine is long-term as compared to a control group.
Tough call, glad I donât have to make it. There is the argument that continuing as planned is for the greater good, and that those who signed on did so with the knowledge that they might get the placebo. There is also the argument that any participant at risk for a bad outcome should get the real deal now
I donât see it that way at all.
First, the major public health measures for covid include the decidedly non-traditional mask and social distancing protocols.
Second, fewer than half of the adults in this country got a flu shot during the 2018-19 season. We as a nation donât use vaccinations very effectively now, so expecting two-thirds or more of us to line up for a two-stage covid vaccine is not very realistic.
Third, acquiring immunity from having survived the disease can be costly due to the long-term issues some people suffer. Some of those lingering side effects will, in some people, outlast their immunity.
I guess weâll see what happens as time goes on, but keep this in mind: A typical year for flu deaths is about 20,000-45,000. By the time we reach March 15 2021, the one year period of 3/15/2020-3/15/2021 will probably rack up close to or over 500,000 CoViD-19 deaths.
In other words, weâre looking at roughly 15-20 times the average number of dead from the flu each year.
I think thatâs likely to significantly increase CoViD-19 vaccine participation over the usual flu vaccine.
Yeah. Isnât that what the misguided âherd immunityâ plan was based on? I realize that herd immunity is a term normally applied to vaccinated populations but it seems likely that the virus confers varying degrees of immunity because there have only been a few highly publicized cases of re-infection out of millions worldwide.
The âcommon coldâ coronaviruses do not result in long-term immunity and you can get them over and over.
The goal of the vaccines is to prevent disease. It will be nice if they also prevent infection, but itâs going to take a while before we find out about that, or how long protection lasts.
They really havenât had enough testing time to determine a longer period. Itâs kind of like saying âCats may only live three to six monthsâ when you have a four-month old kitten.
Under half is not most people. I fail to see why these people object given that they are completely comfortable being controlled by tinfoil.
