My daughter had covid, and i have it now, we sleep on the same bed, but now that she's negative, can i give it to her again if i sleep with her, since i'm still positive?

Your daughter now has antibodies that are active due to her recent infection so, since you most likely have the same strain, she will be protected with these antibodies. This will prevent her from getting the infection again this soon. Good luck!

I would believe she has been boosted but she can still contract Covid since new strains are always arising. If she is exposed and becomes positive, her previous antibodies and boosters will result in a mild form. Sleeping in same bed is risky and should be avoided for 10 days.
