Getting a Boost

There's a very good and comprehensive article in today’s Washington Post on whether to boost again now or later.  You can read it here.

But if you don't want to read the whole thing or can't access the paper, I mainly note this for one particular passage which I found the most interesting. And comforting –

“The decision about when, whether and who to boost has also been complicated by imperfect data. A widely quoted CDC study showed that protection against severe illness from three shots waned over four months, from 91 percent to 78 percent.

“What was lost in the messaging was that those who had been vaccinated for more than four months in that study were primarily people with poorly functioning immune systems, who typically respond less well to vaccination. When the data was instead limited to people with functioning immune systems, there was little evidence that protection against hospitalization was waning among people 65 and older, according to data presented by Ruth Link-Gelles, part of the CDC’s Epidemiology Task Force at a federal advisory committee meeting this month.”
