If that’s because traveling right now is a pain and wearing a mask on vacation isn’t a vacation, I get it.
If that’s because he’s afraid of giving or getting the vid, I’d assume he got his med school diploma in a CrackerJack box.

He’s had the vid and won’t travel...

Six digit accuracy? That’s an awful lot for a SWAG. Clearly you never had my chemistry instructor’s lecture on significant figures LOL.

Common human coronaviruses
- 229E (alpha coronavirus)
- NL63 (alpha coronavirus)
- OC43 (beta coronavirus)
- HKU1 (beta coronavirus)

These have been extensively studied. Typically, it takes at least six months for immunity to fade enough for someone to get a second infection with any of these coronaviruses.
In a few cases, reinfections occurred as early as 6 months (twice with HCoV-229E and once with HCoV-OC43) and 9 months (once with HCoV-NL63), but reinfections were frequently observed at 12 months (Fig. 1b). For reinfections occurring as early as 6 months, we observed no intermediate reduction in antibodies between infections (Fig. 1b, white circles), but reinfection intervals of more than 6 months did show intermediate reductions between infections (visible as peaks in Fig. 1aand Supplementary Fig. 1). The ability to detect short-term reinfections in this study was limited by the sampling interval, which was, at minimum, 3 months. However, no signs of reinfection were observed at the first subsequent follow-up visit after a 3-month interval (Fig. 1b), as only decreases in antibody levels (optical density (OD) fold changes <1.0) were found (Fig. 1c). We, therefore, concluded that, in our data, the earliest time point for reinfection by seasonal coronaviruses was 6 months.

Since the first known case of COVID-19 in the world was in November, and the numbers really didn’t start to skyrocket until April, nobody really expected to see all that many...yet.
