Very honest look at breakthrough infections amongst HCWs who are already fully vaccinated.. 1/n
nejm.org/doi/full/10.10…
Out of 1497 fully vaccinated HCWs tested, 39 had breakthrough infection.. yet most of these cases were mild or asymptomatic.

Though 19% had persistent symptoms.. 2/n
nejm.org/doi/full/10.10…
Breakdown of the 39 HCWs infected:
18 nurses
10 admin or maintenance
6 allied health
5 physicians
This might not differ much from even Hospital settings in Malaysia, in terms of case proportion by profession.. 3/n
nejm.org/doi/full/10.10…
Source of infection to these cases were also traced; at least 37 of the 39 were from an unvaccinated individual..
21 - household member
11 - fellow HCW or patient
7 of the 11 - nosocomial transmission fr px receiving positive pressure ventilation.. 4/n
nejm.org/doi/full/10.10…
Of the 39 cases..
26 - mild symptoms, with no hospitalization
13 - asymptomatic .. 5/n

And finally the discussion of serological results.. 9/n

All this also points to whether there is a need of booster jabs.. in future decision making.
