Recovering from Covid-19 "doesn't mean you are immunized for life," researcher warns
Get vaccinated. That’s one of the key lessons from the news that a man in Hong Kong contracted the coronavirus twice, in what has been billed as the world’s first documented case of reinfection.

The 33-year-old man tested positive for Covid-19 in late March, then again in mid-August after arriving back in Hong Kong after a trip to Europe, according to a yet-to-be peer-reviewed study from a team at the University of Hong Kong. While he had symptoms the first time around, he didn’t the second time.

The findings are the latest sign that immunity to the virus may not be long-lasting, and underline the importance of having an annual Covid-19 vaccine to boost immunity, even for people who had previously caught the virus, according to Ivan Hung, one of the research team members.

“This virus is very smart, it keeps on mutating. So that means even though you recovered from a natural infection, you still need vaccination, need a mask, and keep your social distancing,” Hung told CNN.

FDA commissioner defends authorization of convalescent plasma
Globally, only a few trials have reported out their results, “and the results are not conclusive,” Dr. Soumya Swaminathan said on Monday, a day after the US Food and Drug Administration (FDA) issued an emergency use authorization for the treatment. US President Donald Trump suggested he pressured the agency to fast-track that authorization, even though it has yet to be tested in a randomized, placebo-controlled clinical trial.

As WHO expressed concern, FDA chief Stephen Hahn wound back comments he made on Sunday, where he incorrectly said the data showed use of convalescent plasma reduced the risk of death by 35%, and said that meant if 100 people got coronavirus, 35 would survive because of the treatment. The study did not show that, and Hahn admitted he had been inaccurate on Monday.

A woman linked to the Coronavirus outbreak at a wedding reception in Maine has died
This is the first death linked to the outbreak that stemmed from a wedding ceremony and reception held in the Millinocket area. On Thursday, officials said that there were 32 positive cases associated with the gatherings. The hospital added that this was their only inpatient admission linked to this outbreak. All other individuals who tested positive were given care instructions and told to quarantine.

The Maine CDC said the wedding reception had approximately 65 guests, which is a violation of the state's requirements for large gatherings that is currently capped at 50 people for indoor events. On Thursday, the Maine CDC said they delivered an imminent health hazard citation to the owners of Big Moose Inn for this violation.
