Isn't the 90 day thing old news?

This was from calculations early on based on the slope of antibody reduction immediately after infection. Longer term studies have shown that the body reacts similar to other viruses. There's an initial rapid decline of antibodies then it levels out. That's in addition to T and B cell responses. As of right now there's no data that shows we will not have long lasting immunity after coming in contact with the virus (or a vaccine when available).

On the vaccine front, JNJ enters Phase III testing. -- Hokie360 09/23/2020 09:13AM

I listened to a panel of speakers a couple of weeks ago -- GreenvilleVT 09/23/2020 10:59AM

I was told to expect shortages on syringes -- No Clue 09/23/2020 1:00PM

They talked about the advantage of one vaccine was no refrigeration needed. -- Hokie360 09/23/2020 12:34PM

Lets make sure the Hokie football and basketball players are "essential" ** -- EDGEMAN 09/23/2020 11:15AM

If they were, they wouldn't have 14 day quarantines for contact tracing. ** -- vthokieq 09/23/2020 11:24AM

Until the vaccine hits the market... ** -- EDGEMAN 09/23/2020 11:28AM

Still curious how long it lasts, current body response is 90 days -- HokieForever 09/23/2020 09:22AM

Everyone below, validity of this article? -- HokieForever 09/23/2020 10:06AM

It seems reasonable. I think at this point it's too early to tell -- jmanatVT 09/23/2020 10:59AM

Better way to say it then I did, +1 ** -- HokieForever 09/23/2020 11:15AM

Where are you getting 90 days from?? -- VTSnake 09/23/2020 10:18AM

CDC Guidance, why football teams, et. al following it -- HokieForever 09/23/2020 10:37AM

I see nothing in there about 90 day immunity. -- VTSnake 09/23/2020 10:43AM

Read the Note: at the top or the quarantine requirements -- HokieForever 09/23/2020 10:45AM

I love the "up to" part. So it really can be anything less than 3 months, ** -- 48zip 09/23/2020 10:52AM

That doesn't mean they're only immune for 90 days. ** -- vthokieq 09/23/2020 10:49AM

There have been tests showing antibodies gone after 90 days hence -- HokieForever 09/23/2020 11:15AM

This has been explained already. Nevermind. ** -- vthokieq 09/23/2020 11:17AM

Yes understand the T-cell argument I am saying why the guidance is 90 days ** -- HokieForever 09/23/2020 11:18AM

I don't think anyone questions where the guidance is coming from. -- vthokieq 09/23/2020 11:23AM

There's more to immunity than antibodies (Same as below with sciency link) -- jmanatVT 09/23/2020 09:54AM

Just my thought process here (didn't stay at a Holiday Inn Express) -- BTHokie 09/23/2020 09:35AM

Agree. The 90 days isn't a definitive time frame for immunity... -- vthokieq 09/23/2020 09:45AM

My hope, too. At least lessen impact of future variants, perhaps. ** -- HokieDiver 09/23/2020 09:44AM
